At present, for broadwell, SDRAM is always set up in U-Boot proper since the 64-bit mode (which uses SDRAM init in SPL) is not supported. Update the code to allow SDRAM init in SPL instead so that U-Boot proper can be loaded into SDRAM and run from there. This allows U-Boot to be compressed to reduce space, since it is not necessary to run it directly from flash. It could later allow us to support 64-bit U-Boot on broadwell. Series-changes: 2 - Update commit message to make it clear this patch is just for broadwell - Bring in sdram_console_tx_byte() to allow debugging Signed-off-by: Simon Glass <sjg@chromium.org>
