Simon Glass	08deb6d36f	x86: Add more comments to the start-up code ... The full start-up sequence (TPL->SPL->U-Boot) can be a bit confusing since each phase has its own 'start' file. Add comments to explain this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>	2019-10-08 13:57:36 +08:00
Simon Glass	051c31b7a4	x86: Add support for starting from SPL/TPL ... When a previous phase of U-Boot has run we need to adjust the init of subsequent states to avoid messing up the CPU state. Add a new version of the start logic for SPL, when it boots from TPL (start_from tpl.c) and a new version for U-Boot when it boots from SPL.
