SPL is using ps7_init.c/h files which are generated from design tools which have to be copied to boards/xilinx/zynq folder before compilation. BSS section is moved to SDRAM because fat support requires more space than SRAM size. Added: - MMC and QSPI support - Boot OS directly from SPL - Enable SPL command Signed-off-by: Michal Simek <michal.simek@xilinx.com> Reviewed-by: Tom Rini <trini@ti.com>
