Hi
On our weekly master upstream CI build we noticed Verdin iMX8M Plus boot
looping.
Bisecting pointed to the following commit:
commit 4b4472438f5a ("imx: spl_imx_romapi: avoid tricky use of
spl_load_simple_fit() to get full FIT size")
It looks like this introduced a regression.
Before and after console output (with DEBUG defined in
arch/arm/mach-imx/spl_imx_romapi.c) below:
Any comments?
Cheers
Marcel
