This patch reduces the console buffer size from 2048 to 1024, thus fixes
OCM overwriting issue.
Differences are in bss section as is shown from output:
xilinx_versal_mini: all -2056 bss -2048 text -8
u-boot: add: 0/0, grow: 0/-3 bytes: 0/-2056 (-2056)
function old new delta
cli_simple_run_command 340 332 -8
static.lastcommand 2049 1025 -1024
console_buffer 2049 1025 -1024
Better would be to use PPU RAM but this change is also aligned with changes
done in ZynqMP mini configurations.
