This allows U-boot based systems to be controlled +remotely using the same PXE based techniques that many non U-boot based servers +use. + +Commands +======== + +pxe get +------- + syntax: pxe get + + follows PXELINUX's rules for retrieving configuration files from a tftp + server, and supports a subset of PXELINUX's config file syntax. + + Environment + ----------- + 'pxe get' requires two environment variables to be set: + + pxefile_addr_r - should be set to a location in RAM large enough to hold + pxe files while they're being processed. Up to 16 config files may be + held in memory at once. The exact number and size of the files varies with + how the system is being used. A typical config file is a few hundred bytes + long. + + bootfile,serverip - these two are typically set in the DHCP response + handler, and correspond to fields in the DHCP response. + + 'pxe get' optionally supports these two environment variables being set: + + ethaddr - this is the standard MAC address for the ethernet adapter in use. + 'pxe get' uses it to look for a configuration file specific to a system's + MAC address. + + pxeuuid - this is a UUID in standard form using lower case hexadecimal + digits, for example, 550e8400-e29b-41d4-a716-446655440000. 'pxe get' uses + it to look for a configuration file based on the system's UUID. + + File Paths + ---------- + 'pxe get' repeatedly tries to download config files until it either + successfully downloads one or runs out of paths to try. The order and + contents of paths it tries mirrors exactly that of PXELINUX - you can + read in more detail about it at: + + http://syslinux.zytor.com/wiki/index.php/Doc/pxelinux + +pxe boot +-------- + syntax: pxe boot [pxefile_addr_r] + + Interprets a pxe file stored in memory. + + pxefile_addr_r is an optional argument giving the location of the pxe file. + The file must be terminated with a NUL byte. + + Environment + ----------- + There are some environment variables that may need to be set, depending + on conditions. + + pxefile_addr_r - if the optional argument pxefile_addr_r is not supplied, + an environment variable named pxefile_addr_r must be supplied. This is + typically the same value as is used for the 'pxe get' command. + + bootfile - typically set in the DHCP response handler based on the + same field in the DHCP respone, this path is used to generate the base + directory that all other paths to files retrieved by 'pxe boot' will use. + If no bootfile is specified, paths used in pxe files will be used as is. + + serverip - typically set in the DHCP response handler, this is the IP + address of the tftp server from which other files will be retrieved. + + kernel_addr_r, initrd_addr_r - locations in RAM at which 'pxe boot' will + store the kernel and initrd it retrieves from tftp. These locations will + be passed to the bootm command to boot the kernel. These environment + variables are required to be set. + + fdt_addr - the location of a fdt blob. If this is set, it will be passed + to bootm when booting a kernel. + +pxe file format +=============== +The pxe file format is nearly a subset of the PXELINUX file format; see +http://syslinux.zytor.com/wiki/index.php/PXELINUX. It's composed of one line +commands - global commands, and commands specific to labels. Lines begining +with # are treated as comments. White space between and at the beginning of +lines is ignored. + +The size of pxe files and the number of labels is only limited by the amount +of RAM available to U-boot. Memory for labels is dynamically allocated as +they're parsed, and memory for pxe files is statically allocated, and its +location is given by the pxefile_addr_r environment variable. The pxe code is +not aware of the size of the pxefile memory and will outgrow it if pxe files +are too large. + +Supported global commands +------------------------- +Unrecognized commands are ignored. + +default <label> - the label named here is treated as the default and is + the first label 'pxe boot' attempts to boot. + +menu title <string> - sets a title for the menu of labels being displayed. + +menu include <path> - use tftp to retrieve the pxe file at <path>, which + is then immediately parsed as if the start of its + contents were the next line in the current file. nesting + of include up to 16 files deep is supported. + +prompt <flag> - if 1, always prompt the user to enter a label to boot + from. if 0, only prompt the user if timeout expires. + +timeout <num> - wait for user input for <num>/10 seconds before + auto-booting a node. + +label <name> - begin a label definition. labels continue until + a command not recognized as a label command is seen, + or EOF is reached. + +Supported label commands +------------------------ +labels end when a command not recognized as a label command is reached, or EOF. + +menu default - set this label as the default label to boot; this is + the same behavior as the global default command but + specified in a different way + +kernel <path> - if this label is chosen, use tftp to retrieve the kernel + at <path>. it will be stored at the address indicated in + the kernel_addr_r environment variable, and that address + will be passed to bootm to boot this kernel. + +append <string> - use <string> as the kernel command line when booting this + label. + +initrd <path> - if this label is chosen, use tftp to retrieve the initrd + at <path>. it will be stored at the address indicated in + the initrd_addr_r environment variable, and that address + will be passed to bootm. + +localboot <flag> - Run the command defined by "localcmd" in the environment. + <flag> is ignored and is only here to match the syntax of + PXELINUX config files. + +Example +------- +Here's a couple of example files to show how this works. + +------------/tftpboot/pxelinux.cfg/menus/linux.list---------- +menu title Linux selections + +# This is the default label +label install + menu label Default Install Image + kernel kernels/install.bin + append console=ttyAMA0,38400 debug earlyprintk + initrd initrds/uzInitrdDebInstall + +# Just another label +label linux-2.6.38 + kernel kernels/linux-2.6.38.bin + append root=/dev/sdb1 + +# The locally installed kernel +label local + menu label Locally installed kernel + append root=/dev/sdb1 + localboot 1 +------------------------------------------------------------- + +------------/tftpboot/pxelinux.cfg/default------------------- +menu include pxelinux.cfg/menus/base.menu +timeout 500 + +default linux-2.6.38 +------------------------------------------------------------- + +When a pxe client retrieves and boots the default pxe file, +'pxe boot' will wait for user input for 5 seconds before booting +the linux-2.6.38 label, which will cause /tftpboot/kernels/linux-2.6.38.bin +to be downloaded, and boot with the command line "root=/dev/sdb1" + +Differences with PXELINUX +========================= +The biggest difference between U-boot's pxe and PXELINUX is that since +U-boot's pxe support is written entirely in C, it can run on any platform +with network support in U-boot. Here are some other differences between +PXELINUX and U-boot's pxe support. + +- U-boot's pxe does not support the PXELINUX DHCP option codes specified + in RFC 5071, but could be extended to do so. + +- when U-boot's pxe fails to boot, it will return control to U-boot, + allowing another command to run, other U-boot command, instead of resetting + the machine like PXELINUX. + +- U-boot's pxe doesn't rely on or provide an UNDI/PXE stack in memory, it + only uses U-boot. + +- U-boot's pxe doesn't provide the full menu implementation that PXELINUX + does, only a simple text based menu using the commands described in + this README. With PXELINUX, it's possible to have a graphical boot + menu, submenus, passwords, etc. U-boot's pxe could be extended to support + a more robust menuing system like that of PXELINUX's. + +- U-boot's pxe expects U-boot uimg's as kernels. Anything that would work + with the 'bootm' command in U-boot could work with the 'pxe boot' command. + +- U-boot's pxe doesn't recognize initrd options in the append command - you + must specify initrd files using the initrd command. + +- U-boot's pxe only recognizes a single file on the initrd command line. It + could be extended to support multiple. + +- in U-boot's pxe, the localboot command doesn't necessarily cause a local + disk boot - it will do whatever is defined in the 'localcmd' env + variable. And since it doesn't support a full UNDI/PXE stack, the + type field is ignored. + +- the interactive prompt in U-boot's pxe only allows you to choose a label + from the menu. If you want to boot something not listed, you can ctrl+c + out of 'pxe boot' and use existing U-boot commands to accomplish it. diff --git a/doc/README.sandbox b/doc/README.sandbox new file mode 100644 index 0000000000..04692b34fa --- /dev/null +++ b/doc/README.sandbox @@ -0,0 +1,53 @@ +/* + * Copyright (c) 2011 The Chromium OS Authors. + * + * See file CREDITS for list of people who contributed to this + * project. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License as + * published by the Free Software Foundation; either version 2 of + * the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

To achieve this it builds U-Boot (so far as possible) +as a normal C application with a main() and normal C libraries. + +All of U-Boot's architecture-specific code therefore cannot be built as part +of the sandbox U-Boot. The purpose of running U-Boot under Linux is to test +all the generic code, not specific to any one architecture. The idea is to +create unit tests which we can run to test this upper level code. + +CONFIG_SANDBOX is defined when building a native board. + +The chosen vendor and board names are also 'sandbox', so there is a single +board in board/sandbox/sandbox. + +CONFIG_SANDBOX_BIG_ENDIAN should be defined when running on big-endian +machines. + +Note that standalone/API support is not available at present. + +The serial driver is a very simple implementation which reads and writes to +the console. It does not set the terminal into raw mode, so cursor keys and +history will not work yet. + + +Tests +----- + +So far we have no tests, but when we do these will be documented here. diff --git a/drivers/bios_emulator/x86emu/debug.c b/drivers/bios_emulator/x86emu/debug.c index 241acf3a89..6417d09998 100644 --- a/drivers/bios_emulator/x86emu/debug.c +++ b/drivers/bios_emulator/x86emu/debug.c @@ -39,6 +39,7 @@ #include <stdarg.h> #include <common.h> +#include <linux/ctype.h> #include "x86emu/x86emui.h" /*----------------------------- Implementation ----------------------------*/ @@ -333,7 +334,7 @@ static int x86emu_parse_line(char *s, int *ps, int *n) int cmd; *n = 0; - while (*s == ' ' || *s == '\t') + while (isblank(*s)) s++; ps[*n] = *s; switch (*s) { @@ -346,13 +347,13 @@ static int x86emu_parse_line(char *s, int *ps, int *n) } while (1) { - while (*s != ' ' && *s != '\t' && *s != '\n') + while (!isblank(*s) && *s != '\n') s++; if (*s == '\n') return cmd; - while (*s == ' ' || *s == '\t') + while (isblank(*s)) s++; *n += 1; diff --git a/drivers/gpio/kw_gpio.c b/drivers/gpio/kw_gpio.c index 56383c2875..2de179e827 100644 --- a/drivers/gpio/kw_gpio.c +++ b/drivers/gpio/kw_gpio.c @@ -109,7 +109,7 @@ void kw_gpio_set_valid(unsigned pin, int mode) */ int kw_gpio_direction_input(unsigned pin) { - if (!kw_gpio_is_valid(pin, GPIO_INPUT_OK)) + if (kw_gpio_is_valid(pin, GPIO_INPUT_OK) != 0) return 1; /* Configure GPIO direction. */ diff --git a/drivers/net/dm9000x.c b/drivers/net/dm9000x.c index b5c55738f7..04241109cc 100644 --- a/drivers/net/dm9000x.c +++ b/drivers/net/dm9000x.c @@ -116,13 +116,21 @@ static u8 DM9000_ior(int); static void DM9000_iow(int reg, u8 value); /* DM9000 network board routine ---------------------------- */ - +#ifndef CONFIG_DM9000_BYTE_SWAPPED #define DM9000_outb(d,r) writeb(d, (volatile u8 *)(r)) #define DM9000_outw(d,r) writew(d, (volatile u16 *)(r)) #define DM9000_outl(d,r) writel(d, (volatile u32 *)(r)) #define DM9000_inb(r) readb((volatile u8 *)(r)) #define DM9000_inw(r) readw((volatile u16 *)(r)) #define DM9000_inl(r) readl((volatile u32 *)(r)) +#else +#define DM9000_outb(d, r) __raw_writeb(d, r) +#define DM9000_outw(d, r) __raw_writew(d, r) +#define DM9000_outl(d, r) __raw_writel(d, r) +#define DM9000_inb(r) __raw_readb(r) +#define DM9000_inw(r) __raw_readw(r) +#define DM9000_inl(r) __raw_readl(r) +#endif #ifdef CONFIG_DM9000_DEBUG static void diff --git a/drivers/serial/Makefile b/drivers/serial/Makefile index 1dcc1c7f6a..6309549fce 100644 --- a/drivers/serial/Makefile +++ b/drivers/serial/Makefile @@ -53,6 +53,7 @@ COBJS-$(CONFIG_SA1100_SERIAL) += serial_sa1100.o COBJS-$(CONFIG_S3C24X0_SERIAL) += serial_s3c24x0.o COBJS-$(CONFIG_S3C44B0_SERIAL) += serial_s3c44b0.o COBJS-$(CONFIG_XILINX_UARTLITE) += serial_xuartlite.o +COBJS-$(CONFIG_SANDBOX_SERIAL) += sandbox.o COBJS-$(CONFIG_SCIF_CONSOLE) += serial_sh.o COBJS-$(CONFIG_TEGRA2) += serial_tegra2.o diff --git a/drivers/serial/sandbox.c b/drivers/serial/sandbox.c new file mode 100644 index 0000000000..0d65587f71 --- /dev/null +++ b/drivers/serial/sandbox.c @@ -0,0 +1,63 @@ +/* + * Copyright (c) 2011 The Chromium OS Authors. + * See file CREDITS for list of people who contributed to this + * project. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License as + * published by the Free Software Foundation; either version 2 of + * the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
