[U-Boot] [PATCH] ARM: kirkwood: add spi0 alias for dreamplug
The conversion to DM_SPI managed to break accessing the environment on dreamplug. This is because the environment code relies on being to able to select the SPI device based on the sequence number. Add an alias so that the spi0 bus gets sequence number 0.

Could you test this on your system for me. I'm only able to compile test this myself.

Great. Thanks again for the bug report.
Slightly related I've got a series of changes for USB on kirkwood. Would you be in a position to take them for a spin?
