Hi U-Booters,
I get the following warning when I boot our openrd based board:
U-Boot 2012.07 (Aug 17 2012 - 10:45:29) OpenRD-Base
SoC: Kirkwood 88F6281_A1 DRAM: 128 MiB WARNING: Caches not enabled NAND: 512 MiB
I am running the latest code from git with a small number of changes to make it work with our hardware. (In particular we have had to rewrite board/Marvell/openrd/kwbimage.cfg.)
My question is: does the warning about caches affect only U-Boot (in which case I don't mind) or will it also affect Linux?
As fair as I know, it will only affect u-boot. If I remember correctly, caches are disabled (and fulshed) just before passing execution to linux.
Those caches are disabled, since some time ago it turns out, that many drivers had problems with unaligned buffers allocation.
TIA,
