Hi,
trying to boot recent mainline v4.14-rc4 on a custom H3 ES2.0 board with
rootfs on SD card I'm getting [1].
Last time I think I used v4.13 in the same environment and I think it
worked fine, most probably because renesas_sdhi_internal_dmac wasn't
there, yet ;)
I checked renesas-drivers-2017-10-03-v4.14-rc3 if there is anything
newer regarding drivers/mmc/host/renesas_sdhi_internal_dmac.c but
doesn't look so.
Any idea what I missed?
Best regards
Dirk
