2014-11-21x86: ifdtool: Allow creation of an empty ROMSimon Glass
Allow an empty ROM to be created, without needing to provide a descriptor. The descriptor is not needed on some x86 boards. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-11-21x86: Allow timer calibration to work on ivybridgeSimon Glass
Unfortunately MSR_FSB_FREQ is not available on this CPU, and the PIT method seems to take up to 50ms which is much too long. For this CPU we know the frequency, so add another special case for now. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: use CONFIG_SYS_COREBOOT to descend into coreboot/ directoryMasahiro Yamada
The references of CONFIG_SYS_COREBOOT in arch/x86/cpu/coreboot/Makefile are redundant because the build system descends into the directory only when CONFIG_SYS_COREBOOT is defined.

2014-11-21x86: Replace fill_processor_name() with cpu_get_name()Simon Glass
This implementation has a 'cpu' prefix and returns a pointer to the string, avoiding the need for copying. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2014-11-21x86: config: Move common x86 configs to a common fileSimon Glass
Many of the x86 CONFIG options will be common across different boards. Move them to a common file. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: Add ifdtool for working with Intel Flash Descriptor ROM imagesSimon Glass
Newer Intel chips require a Management Engine which requires a particular format for the SPI flash that contains the boot loader. Add a tool that supports creating and modifying these ROM images. This tool is from Chrome OS but has been cleaned up to use U-Boot style and to add comments. A few features have been added also. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-11-21dm: gpio: Add a function to read an ID from a list of GPIOsSimon Glass
For board IDs a common approach is to set aside several GPIOs for use in determining the board ID. This can provide information about board features and the revision. Add a function that turns a list of GPIOs into an integer by assigning each GPIO to a single bit. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-11-21dm: serial: Move current serial port pointer to global_dataSimon Glass
In general we can't store things in the data section until we have inited SDRAM. Some platforms allow this (e.g. those with SPL) but some don't. Move the pointer to global_data so that it will work on all platforms. Without this fix the serial port will not work prior to relocation with driver model on some platforms.

2014-11-21fdt: Add a function to decode a variable-sized u32 arraySimon Glass
Sometimes an array can be of variable size up to a maximum. Add a helper function to decode this. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-11-21Move early malloc() to before arch_cpu_init()Simon Glass
For some CPUs, having malloc() available very early is useful. There is no reason to delay this since early malloc is allocated before board_init_f() is called. Move early malloc() init nearer to the start of the init sequence. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-11-21x86: Fix a warning with gcc 4.4.4Simon Glass
This warning appears even though it seems that the compiler could work it out. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>

2014-11-21x86: Do TSC MSR calibration only for known/supported CPUsBin Meng
Using MSR_PLATFORM_INFO (0xCE) to calibrate TSR will cause #GP on processors which do not have this MSR. Instead only doing the MSR calibration for known/supported CPUs. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
2014-11-21x86: Do CPU identification in the early phaseBin Meng
The CPU identification happens in x86_cpu_init_f() and corresponding fields are saved in the global data for later use. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: Save the BIST value on resetSimon Glass
The built in self test value is available in register eax on start-up. Save it so that it can be accessed later. Unfortunately we must wait until the global_data is available before we can do this, so there is a little bit of shuffling to keep it around.

2014-11-19powerpc: mpc52xx: Clear GD in the main U-Boot stage for SPL usageStefan Roese
When an MPC5200 based board is used with SPL support, the main U-Boot needs to clear the GD (global data) struct again. Otherwise the generic board init code in board_init_f (when CONFIG_SYS_GENERIC_BOARD is defined) will not initialize all GD variables correctly. Resulting in a hangup on the a4m2k board.

As in SAMA5D4 SoC, the gf table in ROM code can not be seen. So, when we try to use PMECC, we need to build it when do initialization. Add a macro NO_GALOIS_TABLE_IN_ROM in soc header file. If it is defined we will build gf table runtime. The PMECC use the BCH algorithm, so based on the build_gf_tables() function in lib/bch.c, we can build the Galois Field lookup table.
