Thanks.

BTW: Is this series also tested on a board with SPL_DM and
DM_SPI and DM_SPI_FLASH enabled? By loading in SPL the main
U-Boot image via SPI NOR flash?

I'm asking since I'm currently struggling to get this working
on MVEBU. And am experiencing problems with the DM SPI
bus and device probing. Without SPL_DM this is working just
fine.

Thanks,
Stefan
