2011-07-16Add uboot "fdt_high" enviroment variableDavid A. Long
Add a new "fdt_high" enviroment variable. This can be used to control (or prevent) the relocation of the flattened device tree on boot. It can be used to prevent relocation of the fdt into highmem. The variable behaves similarly to the existing "initrd_high" variable. Signed-off-by: David A. Long <dave.long@linaro.org>

2011-07-04armv7: add PL310 support to u-bootAneesh V
PL310 is the L2$ controller from ARM used in many SoCs including the Cortex-A9 based OMAP4430 Add support for some of the key PL310 operations - Invalidate all - Invalidate range - Flush(clean & invalidate) all - Flush range Signed-off-by: Aneesh V <aneesh@ti.com>
2011-07-04armv7: cache maintenance operations for armv7Aneesh V
- Add a framework for layered cache maintenance - separate out SOC specific outer cache maintenance from maintenance of caches known to CPU - Add generic ARMv7 cache maintenance operations that affect all caches known to ARMv7 CPUs. For instance in Cortex-A8 these opertions will affect both L1 and L2 caches. In Cortex-A9 these will affect only L1 cache - D-cache operations supported: - Invalidate entire D-cache - Invalidate D-cache range - Flush(clean & invalidate) entire D-cache - Flush D-cache range - I-cache operations supported: - Invalidate entire I-cache - Add maintenance functions for TLB, branch predictor array etc. - Enable -march=armv7-a so that armv7 assembly instructions can be used Signed-off-by: Aneesh V <aneesh@ti.com>
2011-07-01NAND: Add 16bit NAND support for the NDFCAlex Waterman
This patch adds support for 16 bit NAND devices attached to the NDFC on ppc4xx processors. Two config entries were added: CONFIG_SYS_NDFC_16 - Setting this tells the NDFC that a 16 bit device is attached. CONFIG_SYS_NDFC_EBC0_CFG - This is for the External Bus Controller configuration register. Also, a new ndfc_read_byte() function was added which does not first convert the data to little endian. The NAND SPL was also modified to do 16bit bad block testing when a 16 bit chip is being used. Signed-off-by: Alex Waterman <awaterman@dawning.com> Signed-off-by: Scott Wood <scottwood@freescale.com>

2011-05-20powerpc/fsl_pci: Fix device tree fixups for newer platformsKumar Gala
We assumed that only a small set of compatiable strings would be needed to find the PCIe device tree nodes to be fixed up. However on newer platforms the simple rules no longer work. We need to allow specifying the PCIe compatiable string for each individual SoC. We introduce CONFIG_SYS_FSL_PCIE_COMPAT for this purpose and set it if the default isn't sufficient.

2011-04-30cmd_ide: enhance new feature "CONFIG_IDE_AHB"Macpaul Lin
Although most IDE controller is designed to be connected to PCI bridge, there are still some IDE controller support AHB interface for SoC design. The driver implementation of these IDE-AHB controllers differ from other IDE-PCI controller, some additional registers and commands access is required during CMD/DATA I/O. Hence a configuration "CONFIG_IDE_AHB" in cmd_ide.c is required to be defined to support these kinds of SoC controllers. Such as Faraday's FTIDE020 series and Global Unichip's UINF-0301.

2011-04-28powerpc: use 'video-mode' environment variable to configure DIUTimur Tabi
Use the 'video-mode' environment variable (for Freescale chips that have a DIU display controller) to designate the full video configuration. Previously, the DIU driver used the 'monitor' variable, and it was used only to determine the output video port. The old definition of the "monitor" environment variable only determines which video port to use for output. This variable was set to a number (0, 1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port. The resolution was hard-coded into board-specific code. The Linux command-line arguments needed to be hard-coded to the proper video definition string. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Anatolij Gustschin <agust@denx.de>
2011-04-28common: add a grepenv commandKim Phillips
u-boot environments, esp. when boards are shared across multiple users, can get pretty large and time consuming to visually parse. The grepenv command this patch adds can be used in lieu of printenv to facilitate searching. grepenv works like printenv but limits its output only to environment strings (variable name and value pairs) that match the user specified substring. the following examples are on a board with a 5313 byte environment that spans multiple screen pages: Example 1: summarize ethernet configuration: => grepenv eth TSEC etact=FM1@DTSEC2 eth=FM1@DTSEC4 ethact=FM1@DTSEC2 eth1addr=00:E0:0C:00:8b:01 eth2addr=00:E0:0C:00:8b:02 eth3addr=00:E0:0C:00:8b:03 eth4addr=00:E0:0C:00:8b:04 eth5addr=00:E0:0C:00:8b:05 eth6addr=00:E0:0C:00:8b:06 eth7addr=00:E0:0C:00:8b:07 eth8addr=00:E0:0C:00:8b:08 eth9addr=00:E0:0C:00:8b:09 ethaddr=00:E0:0C:00:8b:00 netdev=eth0 uprcw=setenv ethact $eth;setenv filename p4080ds/R_PPSXX_0xe/rcw_0xe_2sgmii_rev2_high.bin;setenv start 0xe8000000;protect off all;run upimage;protect on all upuboot=setenv ethact $eth;setenv filename u-boot.bin;setenv start eff80000;protect off all;run upimage;protect on all upucode=setenv ethact $eth;setenv filename fsl_fman_ucode_P4080_101_6.bin;setenv start 0xef000000;protect off all;run upimage;protect on all usdboot=setenv ethact $eth;tftp 1000000 $dir/$bootfile;tftp 2000000 $dir/initramfs.cpio.gz.uboot;tftp c00000 $dir/p4080ds-usdpaa.dtb;setenv bootargs root=/dev/ram rw console=ttyS0,115200 $othbootargs;bootm 1000000 2000000 c00000; => Example 2: detect unused env vars: => grepenv etact etact=FM1@DTSEC2 => Example 3: reveal hardcoded variables; e.g., for fdtaddr: => grepenv fdtaddr fdtaddr=c00000 nfsboot=setenv bootargs root=/dev/nfs rw nfsroot=$serverip:$rootpath ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname:$netdev:off console=$consoledev,$baudrate $othbootargs;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr - $fdtaddr ramboot=setenv bootargs root=/dev/ram rw console=$consoledev,$baudrate $othbootargs;tftp $ramdiskaddr $ramdiskfile;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr $ramdiskaddr $fdtaddr => grep $fdtaddr fdtaddr=c00000 my_boot=bootm 0x40000000 0x41000000 0x00c00000 my_dtb=tftp 0x00c00000 $prefix/p4080ds.dtb nohvboot=tftp 1000000 $dir/$bootfile;tftp 2000000 $dir/$ramdiskfile;tftp c00000 $dir/$fdtfile;setenv bootargs root=/dev/ram rw ramdisk_size=0x10000000 console=ttyS0,115200;bootm 1000000 2000000 c00000; => This patch also enables the grepenv command by default on corenet_ds based boards (and repositions the DHCP command entry to keep the list sorted).

This patch adds a function getenv_bootm_mapsize() for obtaining the size of the early mapped region accessible by the kernel during early boot. It defaults to CONFIG_SYS_BOOTMAPSZ, or if not defined, defaults to getenv_bootm_size(), which in turn defaults to the size of RAM. getenv_bootm_mapsize() can also be overridden with a "bootm_mapsize" environmental variable.

2011-01-14powerpc/8xxx: Refactor SRIO initialization into common codeKumar Gala
Moved the SRIO init out of corenet_ds and into common code for 8xxx/QorIQ processors that have SRIO. We mimic what we do with PCIe controllers for SRIO. We utilize the fact that SRIO is over serdes to determine if its configured or not and thus can setup the LAWs needed for it dynamically. We additionally update the device tree (to remove the SRIO nodes) if the board doesn't have SRIO enabled. Introduced the following standard defines for board config.h: CONFIG_SYS_SRIO - Chip has SRIO or not CONFIG_SRIO1 - Board has SRIO 1 port available CONFIG_SRIO2 - Board has SRIO 2 port available (where 'n' is the port #) CONFIG_SYS_SRIOn_MEM_VIRT - virtual address in u-boot CONFIG_SYS_SRIOn_MEM_PHYS - physical address (for law setup) CONFIG_SYS_SRIOn_MEM_SIZE - size of window (for law setup) [ These mimic what we have for PCI and PCIe controllers ] Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Wolfgang Denk <wd@denx.de>

This adds support for for the PCA9535/PCA9539 family of gpio devices which have 16 output pins. To let the driver know which devices are 16-pin it is necessary to define CONFIG_SYS_I2C_PCA953X_WIDTH in your board config file. This is used to create an array of {chip, ngpio} tuples that are used to determine the width of a particular chip. For backwards compatibility it is assumed that any chip not defined in CONFIG_SYS_I2C_PCA953X_WIDTH has 8 pins.
