Add support for some important configuration options and FSP memory init. The memory init uses swizzle tables from the device tree. Support for the FSP_S binary is also included. Bootstage timing is used for both FSP_M and FSP_S and memory-mapped SPI reads. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
