2011-10-17sandbox: Add bootm supportSimon Glass
This adds sandbox architecture support to bootm, although it is probably not useful to load sandbox code into the address space and execute it. This change at least make the file build correctly on 64-bit machines. Signed-off-by: Simon Glass <sjg@chromium.org>

2011-10-17Add pxe commandJason Hobbs
Add pxe command, which is intended to mimic PXELINUX functionality. 'pxe get' uses tftp to retrieve a file based on UUID, MAC address or IP address. 'pxe boot' interprets the contents of PXELINUX config like file to boot using a specific initrd, kernel and kernel command line. This patch also adds a README.pxe file - see it for more details on the pxe command. Signed-off-by: Jason Hobbs <jason.hobbs@calxeda.com>

2011-10-15common: fix missing function pointer relocation in fixup_cmdtable()Daniel Schwierzeck
The command auto-completion does not work on architectures relying on CONFIG_NEEDS_MANUAL_RELOC like MIPS. Cause is the missing function pointer fixup for cmd_tbl_t::complete function in fixup_cmdtable(). This patch adds the missing pointer fixup in case of CONFIG_AUTO_COMPLETE is defined.

2011-10-15fdt: update fdt_alloc_phandle to use fdt_get_phandleTimur Tabi
The device tree compiler, dtc, can use "phandle" and/or "linux,phandle" properties to specify the phandle for any node. By default, it uses both, but "linux,phandle" is deprecated. One day, we'd like to stop using "linux,phandle", but U-boot needs to support both properties equally first. fdt_alloc_phandle() generates a unique phandle, but it was only checking the "linux,phandle" properties. Instead, we use fdt_get_phandle(), which checks both properties automatically. This ensures that we support dtbs that only use "phandle". The side-effect is that fdt_alloc_phandle() now takes twice as long, since it has to check for two properties instead of one in each node that it searches. Signed-off-by: Timur Tabi <timur@freescale.com>
2011-10-15fdt: check for fdt errors in fdt_create_phandleTimur Tabi
fdt_create_phandle() was ignoring errors from fdt_set_phandle(). If an error occurs, print an error message and return 0, which is an invalid phandle. We also need to change the return type for fdt_create_phandle() to indicate that it cannot return an error code. Signed-off-by: Timur Tabi <timur@freescale.com>

2011-10-05console: Implement pre-console bufferGraeme Russ
Allow redirection of console output prior to console initialisation to a temporary buffer. To enable this functionality, the board (or arch) must define: - CONFIG_PRE_CONSOLE_BUFFER - Enable pre-console buffer - CONFIG_PRE_CON_BUF_ADDR - Base address of pre-console buffer - CONFIG_PRE_CON_BUF_SZ - Size of pre-console buffer (in bytes) The pre-console buffer will buffer the last CONFIG_PRE_CON_BUF_SZ bytes Any earlier characters are silently dropped.

2011-10-04Revert "GCC4.6: Convert various empty macros to inline functions"Wolfgang Denk
This reverts commit 60ce53cf9f408d9ad721f8e7a87d6a564e6d5bac. The commit causes build breakage for a number of boards. This results from the fact that now the arguments of debug() actually get referenced (even if there is hope that the compiler will optimize away the debug() call). The obvious fix to that probem (change the code to always declare the referenced variables and data structures) increases the code size, and was this rejected. So it was decided to revert this commit until a better solution is found.

2011-09-29powerpc/mpc83xx: Migrate from spd_sdram to unified DDR driverYork Sun
Unified DDR driver is maintained for better performance, robustness and bug fixes. Upgrading to use unified DDR driver for MPC83xx takes advantage of overall improvement. It requires changes for board files to customize platform-dependent parameters. To utilize the unified DDR driver, a board needs to define CONFIG_FSL_DDRx in the header file. No more boards will be accepted without such definition. Note: the workaround for erratum DDR6 for the very old MPC834x Rev 1.0/1.1 and MPC8360 Rev 1.1/1.2 parts is not migrated to unified driver.

2011-09-10Add assert() for debug assertionsSimon Glass
assert() is like BUG_ON() but compiles to nothing unless DEBUG is defined. This is useful when a condition is an error but a board reset is unlikely to fix it, so it is better to soldier on in hope. Assertion failures should be caught during development/test. It turns out that assert() is defined separately in a few places in U-Boot with various meanings. This patch cleans up some of these. Build errors exposed by this change (and defining DEBUG) are also fixed in this patch. Signed-off-by: Simon Glass <sjg@chromium.org>

2011-09-07common: fix behavior of ROUND macro when input is already roundedAnton Staaf
Currently when you call ROUND with a value that is already a multiple of the second parameter it will return a value that is one multiple larger, instead of returning the value passed in. There are only two types of usage of ROUND currently, one in various config files to round CONFIG_SYS_MALLOC_LEN to a multiple of 4096 bytes. The other in cmd_sf.c where the incorrect behavior of ROUND is worked around be subtracting one from the length argument before passing it to ROUND. This patch fixes ROUND and removes the workaround from cmd_sf. It also results in all of the malloc pools that use ROUND to compute their size shrinking by 4KB.

2011-09-05Flush cache after the OS image is loaded into the memory.Diana CRACIUN
Since we are loading an executable image into memory we need flush it out of the cache to possible maintain coherence on CPUs with split instruction and data caches. We do this for other executable image loading command. On PowerPC once we do this we no longer need to explicitly flush the dcache on multi-core systems in the BOOTM_STATE_OS_PREP phase. We now treat the BOOTM_STATE_OS_PREP as a no-op to maintain backwards compatibility with the bootm subcommand.
