Per Intel FSP architecture specification, FSP provides 3 routines for bootloader to call. The first one is the TempRamInit (aka Cache-As-Ram initialization) and the second one is the FspInit which does the memory bring up (like MRC for other x86 targets) and chipset initialization. Those two routines have to be called before U-Boot jumping to board_init_f in start.S. The FspInit() will return several memory blocks called Hand Off Blocks (HOBs) whose format is described in Platform Initialization (PI) specification (part of the UEFI specication) to the bootloader. Save this HOB address to the U-Boot global data for later use. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org> |
