Subject: [PATCH] arm64: versal: Fix for OCM overwriting issue
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.
