Sounds good. I tried this approach.
However, when I try to manipulate the env var I am not able to boot:
U-Boot 2012.10-09480-g6b08fc3-dirty (Oct 23 2012 - 15:24:03)
Board: MX53 LOCO
I2C: ready
DRAM: 1 GiB
...
These are my simple changes (just to show the issue I am facing):
--- a/board/freescale/mx53loco/mx53loco.c
+++ b/board/freescale/mx53loco/mx53loco.c

+ char *e;

+ e = getenv("panel");

if (ret)
printf("LCD cannot be configured: %d\n", ret);
}
Any ideas?
Thanks,
