2014-11-21x86: Add processor functions to halt and get stack pointerSimon Glass
Add a function to get the stack pointer and another to halt the CPU. 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. Signed-off-by: Simon Glass <sjg@chromium.org>
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: Save TSC frequency in the global dataBin Meng
Return the saved TSC frequency in get_tbclk_mhz(). 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: Add quick TSC calibration via PITBin Meng
Use the same way that Linux does for quick TSC calibration via PIT when calibration via MSR fails. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-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.

2014-11-21x86: Fix up some missing prototypesSimon Glass
Some functions are missing prototypes. Fix those that are specific to x86. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: Use the standard arch_cpu_init() functionSimon Glass
Instead of an x86-specific cpu_init_f() function, use the normal U-Boot one for this purpose. Also remove a useless/misleading comment. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: Use the standard dram_init() functionSimon Glass
Instead of having an x86-specific DRAM init function, adjust things so we can use the normal one. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: Tidy up global descriptor table setupSimon Glass
This code is a little muddled, so tidy it up. Make sure that we put the GDT in the right place and set it up properly. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: Invalidate TLB as early as possibleSimon Glass
We should invalidate the TLB right at the start to ensure that we don't get false address translations even though paging is disabled. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: Remove board_init16() call which is not usedSimon Glass
This allows a board to do very early init, but no boards need to do this. We may as well drop this feature. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: Remove REALMODE_BASE which is no longer usedSimon Glass
This was missed when the real mode support was dropped. Remove it. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-20linux/kernel.h: add typechecking to roundup macroMasahiro Yamada
This commit replaces roundup macro with the one from Linux Kernel. DEFINE_ALIGN_BUFFER must be fixed because typechecking can not be used in this context. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-11-20linux/kernel.h: import more macrosMasahiro Yamada
These macros seem to be useful for U-Boot too (or at least harmless). Imported from Linux 3.18-rc2. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-11-20include: move various macros to include/linux/kernel.hMasahiro Yamada
U-Boot has imported various utility macros from Linux scattering them to various places without consistency. In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN, container_of, DIV_ROUND_UP, etc. In include/linux/compat.h are min_t, max_t, round_up, round_down, etc. We also have duplicated defines of min_t in some *.c files. Moreover, we are suffering from too cluttered include/common.h. This commit moves various macros that originate in include/linux/kernel.h of Linux to their original position. Note: This commit simply moves the macros; the macros roundup, min, max, min2, max3, ARRAY_SIZE are different from those of Linux at this point.

2014-11-20include/common.h: remove DIV_ROUND definitionMasahiro Yamada
All the references of DIV_ROUND have been replaced with DIV_ROUND_CLOSEST. Remove DIV_ROUND. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-11-20replace DIV_ROUND with DIV_ROUND_CLOSESTMasahiro Yamada
The Linux-compatible macro DIV_ROUND_CLOSEST is a bit more flexible and safer than DIV_ROUND. For example, foo = DIV_ROUND_CLOSEST(x, y++) works expectedly, but foo = DIV_ROUND(x, y++) does not. (y is incremented twice.) Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
