* arm: implement ELF relocationsAlbert Aribaud2010-10-13-290/+156
| | | | | | | | ELF relocation tables generated with linker option -pie can be used to fixup code and data in a single loop at relocation, removing the need for manual fixups anywhere else in the code. Signed-off-by: Albert Aribaud <albert.aribaud@free.fr>
* board/armltd/integrator/split_by_variant.sh: fix 'echo -n'Andreas Bießmann2010-10-13-72/+57
| | | | | | | | | | | | | | This patch fixes an error when running MAKEALL for ARM9. On OS X /bin/sh uses builtin echo which does not utilise '-n' switch. GNU manual for builtins recomend to use here-document style to solve this portability issue. This patch removes the usage of 'echo -n' and replace by here-document style or a oneline echo command.

* ARMV7: Fixed baudrate setting in pl01x driverMatt Waddel2010-10-13-55/+38
| | | | | | | | | The pl01x serial driver was lacking the code to switch baudrates from the command line. Fixed by simply saving the new baudrate and calling serial_init() again. Also fixed CamelCase variables, I/O accessors and comment style. Signed-off-by: Matt Waddel <matt.waddel@linaro.org>
* ARMV7: Versatile Express Coretile CortexA9x4 supportMatt Waddel2010-10-13-0/+734
| | | | | | | | | | | | | | | Adds support for the ARM quad-core Cortex-A9 processor This system includes a motherboard(Versatile Express), daughterboard (Coretile), and SOC(Cortex-A9 quad core). The serial port, ethernet, and flash systems work with these additions. The naming convention is: SOC -> CortexA9 quad core = ca9x4 daughterboard -> Coretile = ct motherboard -> Versatile Express = vxp This gives ca9x4_ct_vxp.c as the board support file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is observed that, in most of the board configs the code is being duplicated, also for any common change all board files needs update This issue was under discussion from long on mailing list and we converge on introducing common config file. With this patch- 1. Total Kirkwood specific configuration code is reduced by 210 lines 2. All common configuration can be shared by multiple boards 3. Easy to manage common updates like ARM relocation changes mv-common.h file is added to include/configs/ It contains all common configuration supported for all Kirkwood boards The respective board configs are updated for its usage Build tested for guruplug, mv88f6281gtw_ge, openrd_base, rd6281a and sheevaplug Binary execution tested for sheevaplug Todo: 1. Other custom Kirkwood boards to be synced 2. The support to be extended for Orion5X based boards Signed-off-by: Prafulla Wadaskar <prafulla@marvell.com>

| * at91: Add arch_preboot_os which disables PIT in a faster wayAlexander Stein2010-10-05-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | When disabled the PIT runs until it reaches the CPIV value. The Linux PIT driver stops the PIT and waits until it stopped. This can take over 100ms. Simply stopping in u-boot isn't sufficient as the PIT will still be running when Linux is waiting until it stopped. So, we stop it in u-boot by setting the compare value to a value slightly greater than the current running counter to make the PIT stopped in short time.

| * | MXC: Fix byte-ordering in SPI driver for i.MX31/i.MX51Stefano Babic2010-09-30-41/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The actual SPI driver for i.MX31 and i.MX51 controller use a wrong byte ordering, because it is supposed to work only with Freescale's devices, as the Power Controllers (PMIC). The driver is not suitable for general purposes, because the buffers passed to spi_xfer must be 32-bit aligned, as it is used mainly to send integer to PMIC devices. The patch drops any kind of limitation and makes the driver useful with devices controlled sending commands composed by single bytes (or by a odd number of bytes), such as spi flash, sensor, etc. Because the byte ordering is changed, any current driver using this controller must be adapted, too.

| * | MXC: Correct SPI_CPOL setting in SPI driverStefano Babic2010-09-30-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The handling of the SPI_CPOL bit inside the SPI driver was wrong. As reported by the manual, the meaning of the SSPOL inside the configuration register is the same as reported by SPI specification (0 if low in idle, 1 is high on idle). The driver inverts this logic. Because this patch sets the logic as specified, it is required to clear the CPOL bit in the configuration file to adapt to the correct logic.

| * | | x86: Implement fully relocatable imageGraeme Russ2010-10-07-24/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | u-boot.bin can be loaded at any 4-byte aligned memory location and directly 'jumped' to using the 'go' command using the load address as the start address. Doing so performs a 'warm boot' which skips memory initialisation and other low-level initialisations, relocates U-Boot to upper memory and starts U-Boot in RAM as per normal 'cold boot'
| * | | x86: Use loops instead of memcpy/memset in board_init_fGraeme Russ2010-10-07-17/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Provides a small speed increase and prepares for fully relocatable image. Downside is the TEXT_BASE, bss, load address etc must ALL be aligned on a a 4-byte boundary which is not such a terrible restriction as everything is already 4-byte aligned anyway

| | | | | | | | | | | | | | | | | | | | | | | | | | | | By reserving space for the Global Data immediately below the stack during assembly level initialisation, the C declaration of the static global data can be removed, along with the 'RAM Bootstrap' function. This results in cleaner code, and the ability to pass boot-up flags from assembler into C

| | | | | | | | | | | | | | | | %ebx will hold low-level boot flags and must be preserved
| * | | x86: Remove usage of %ebp as a return pointerGraeme Russ2010-10-07-13/+12
| | | | | | | | | | | | | | | | Using %ebp as a return pointer prevents creating 'load anywhere' images
