This series moves existing MRC cache codes in the ivybridge cpu
diretory to a common place and makes some changes so that every
x86 board benefits from it. It also updates FSP support codes
to pass MRC cache data to fsp_init() to speed up boot time.
Currently tested on Intel Bayley Bay board. Minnow Max board should
work as it uses the same FSP that Bayley Bay uses. For Chromebook
I cannot test that, but I see Simon added a TODO in the codes below:
/*
* TODO(s...@chromium.org): Skip this for now as it causes boot
* problems
*/
if (0) {
pei_data->mrc_input = mrc_cache->data;
pei_data->mrc_input_len = mrc_cache->data_size;
}
I have no idea what breaks the MRC cache on the Chromebook board.
Simon, you may retest this on top of this series to see if things
go better.
