zynq: Add support for U-BOOT SPL
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
