xilinx: zynqmp: Setup BOARD_SIZE_LIMIT for mini configurations
Setup BOARD_SIZE_LIMIT to 128KB (131072 bytes) for ZynqMP mini/qspi
configurations and enable CONFIG_SKIP_RELOCATE as there is no need
for relocation.
For configurations running from OCM (xilinx_zynqmp_mini_defconfig and
xilinx_zynqmp_mini_qspi_defconfig), move TEXT_BASE from 0xFFFC0000 to
0xFFFE0000. The initial 128KB of OCM (0xFFFC0000-0xFFFDFFFF) is used
for data buffer.
Memory layout in OCM (256KB total):
- 0xFFFC0000 - 0xFFFDFFFF: Data buffer (128KB)
- 0xFFFE0000 - 0xFFFFFFFF: U-Boot code + stack (128KB)
- TEXT_BASE at 0xFFFE0000 (code grows up)
- EARLY SP at 0xFFFE0000 (stack grows down)
EARLY SP is released when new stack location is calculated before U-Boot
prompt that's why no conflict with Data buffer location.
