* | Fix board init code to respect the C runtime environmentAlbert ARIBAUD2016-01-13-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | board_init_f_mem() alters the C runtime environment's stack it is actually already using. This is not a valid behaviour within a C runtime environment. Split board_init_f_mem into C functions which do not alter their own stack and always behave properly with respect to their C runtime environment.

* x86: fsp: Pass mrc cache to fsp_init() and save it to gd after fsp_init()Bin Meng2015-10-21-1/+35
| | | | | | | | | | fsp_init() call has a parameter nvs_buf which is used by FSP as the MRC cache but currently is blindly set to NULL.

* x86: Use struct mrc_region to describe a mrc regionBin Meng2015-10-21-10/+17
| | | | | | | | | | | | | | | | Currently struct fmap_entry is used to describe a mrc region. However this structure contains some other fields that are not related to mrc cache and causes confusion. Besides, it does not include a base address field to store SPI flash's base address. Instead in the mrccache.c it tries to use CONFIG_ROM_SIZE to calculate the SPI flash base address, which unfortunately is not 100% correct as CONFIG_ROM_SIZE may not match the whole SPI flash size. Define a new struct mrc_region and use it instead. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* x86: Add more common routines to manipulate mrc cacheBin Meng2015-10-21-0/+89
| | | | | | | | | | | | | | This adds mrccache_reserve(), mrccache_get_region() and mrccache_save() APIs to the mrccache codes. They are ported from the ivybridge implementation, but with some changes. For example, in the mrccache_reserve(), ivybridge version only reserves the pure MRC data, which causes additional malloc() when saving the cache as the save API needs some meta data. Now we change it to save the whole MRC date plus the meta data to elinimate the need for the malloc() later. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
