From a85f388565063404ec6cd8b908094c0e3e6472e3 Mon Sep 17 00:00:00 2001 From: Ashok Reddy Soma Date: Mon, 9 Sep 2019 03:31:08 -0600 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.
