* fdt: send all dtc output to stderrStephen Warren2012-07-09-1/+1
| | | | | | | | | | | | | | | | | | | | | | Commit 896bbb5 "fdt: avoid bad MAKEALL status" added logic to capture the result code from dtc by echoing $? to stdout and capturing it using $(). However, dtc emits some diagnostics to stderr and some to stdout. The diagnostics send to stdout ended up getting captured via $() rather than being echo'd to the user. This caused those diagnostics to be passed to the exit command, which would then fail with the following cryptic error message: /bin/sh: line 1: exit: too many arguments Solve this by redirecting all dtc output to stderr so that $() does not capture it. This allows the user to see the actual error message from dtc.

| * ARM: cache: Move the cp15 CR register read before flushing the cache.SRICHARAN R2012-07-07-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following is the cleanup sequence in arch/arm/cpu/armv7/cpu.c int cleanup_before_linux(void) { ... ... dcache_disable(); v7_outer_cache_disable(); invalidate_dcache_all(); } 1) invalidate_dcache_all call expects that all the caches has been flushed, invalidated and there are no dirty entries prior to its execution. In the above sequence dcache_disable() flushes, invalidates the caches and turns off the mmu. But after it cleanups the cache and before the mmu is disabled there is a cp_delay() function which has STR instruction. On certain cores like the cortex-a15, cache hit and a write can happen to a cache line even when the dcache is disabled. So the above mentioned STR instruction creates a dirty entry after cleaning. The mmu gets disabled after this. 2) invalidate_dcache_all invalidates the cache lines. Again on cores like cortex-a15, invalidate instruction flushes the dirty line as well. So some times the dirty line from sequence 1 can corrupt the memory resulting in a crash. Fixing this by moving the get_cr() and cp_delay() calls before cleaning up the cache, thus avoiding the dirty entry. Signed-off-by: R Sricharan <r.sricharan@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i2c_probe() is changed to reinit the i2c bus upon read failure. This is naturally the case upon i2c bus probing. Also, some printf messages upon read failure are removed. As they would interfere with the "i2c probe" command. Additionally, i2c_set_bus_speed() now returns 0, so that the "i2c speed" command can be used.

| | | | | | | | | | | | | | | | | | | | | | | | Add support for the M41T82 RTC to the m41t62 driver. The only difference that needs to be handled by this driver, is to clear the HT (Halt Update) bit upon reset. This bit is not used on the M41T62, so its save to clear this bit always.

| | | | | | | | | | | | | | | | | | | | | | | | | | On x600 (SPEAr600) U-Boot is appended to U-Boot SPL. Both images are created using mkimage (crc etc), so that the ROM bootloader can check its integrity. Padding needs to be done to the SPL image (with mkimage header) and not the binary. Otherwise the resulting image which is loaded/copied by the ROM bootloader to SRAM doesn't fit. The resulting image containing both U-Boot images is called u-boot.spr.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the following changes to designware ethernet driver found on the ST SPEAr SoC: - Don't init MAC & PHY upon startup. This causes a delay, waiting for the auto negotiation to complete. And we don't want this delay to always happen. Especially not on platforms where ethernet is not used at all (e.g. booting via flash). Instead postpone the MAC / PHY configuration to the stage, where ethernet is first used. - Add possibility for board specific PHY init code. This is needed for example on the X600 board, where the Vitesse PHY needs to be configured for GMII mode. This board specific PHY init is done via the function designware_board_phy_init(). And this driver now adds a weak default which can be overridden by board code. - Use common functions miiphy_speed() & miiphy_duplex() to read link status from PHY. - Print status and progress of auto negotiation. - Print link status (speed, dupex) upon first usage.

This feature is enabled only for flashing operation i.e. when CONFIG_SPEAR_USBTTY is enabled. This has been tested on SPEAr320, SPEAr600 and SPEAr900 evaluation boards. Following figures show an estimate on the performance improvements. The test setup was a Linux host (not Windows) and involved measurement of only binary transfer time, through kermit. The flash erase and flash copy time would be unaffected by these patches. Another thing is this that the timings remained more or less same across ARM9 and Cortex based devices, hence reporting only one of the cases.

| * SPEAr: Initialize SNOR in early_board_init_fAmit Virdi2012-07-07-0/+9
| | | | | | | | | | | | | | | | | | | | flash reading is required earlier than flash_init is called since the env_init is called before flash_init.

| * SPEAr: Change the default environment variablesVipin KUMAR2012-07-07-9/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies the default environment variables as: 1. Default bootargs: - console=ttyAMA0,115200 - For environment present in NOR flash root=/dev/mtdblock3 - For environment present in NAND flash root=/dev/mtdblock7 - Removes "mem=" option 2. Introduces CONFIG_EXTRA_ENV_USBTTY as default usbtty env var even when usbtty is not selected 3. Add default definitions for nfsboot and ramboot 4. Add a new default environment variable(CONFIG_EXTRA_ENV_UNLOCK) for SPEAr310 and SPEAr320 Signifacance of CONFIG_EXTRA_ENV_USBTTY: This environment variable is important for flashing utility to work. So if somebody accidently erases the env sector then also this variable must be preserved so that flashing utility functions properly. Signifacance of CONFIG_EXTRA_ENV_UNLOCK: This env variable is read by the cfi driver to unlock all flash sectors. This is necessary because the Parallel NOR flash connected on the spear310 and spear320 boards, M28W64, has all its sectors in locked state at reset and these have to be unlocked explicitly before being erased or written.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds options for all the below mentioned configurations and subsequently renames the include/configs/spearxxx.h files to spear3xx_evb.h, spear6xx_evb.h etc to depict evaluation board configuration. SPEAr3xx and SPEAr6xx boards can be compiled in following configurations 1. Environment placed in NAND 2. Console on usb device 3. Console on usb device with environment placed in NAND 4. SPEAr310 and SPEAr320 support environment variables in parallel NOR flash.

| * SPEAr: Eliminate dependency on Xloader tableAmit Virdi2012-07-07-115/+0
| | | | | | | | | | | | | | | | | | | | Xloader table was used primarily to inform u-boot about the DDR size. However, now the ddr size is calculated at runtime which eliminates any need for the Xloader table. So removing this unnecessary code.

| * SPEAr: Fix ARM relocation supportAmit Virdi2012-07-07-19/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While the u-boot code is running from the flash, it is essential that no access is made to the bss segment. This is due to the fact that .rel.dyn and .bss areas overlap and former contains information used in relocation. In SPEAr, this was not taken into consideration. As a result, while the relocation wasn't complete, dram_init populated an uninitialized global variable resulting in corruption of .rel.dyn area, which resulted in u-boot crash. This commit fixes this problem by removing code that accesses bss segment Signed-off-by: Amit Virdi <amit.virdi@st.com> Acked-by: Stefan Roese <sr@denx.de> Signed-off-by: Stefan Roese <sr@denx.de>
