OK, the kernel now boots (using sunxi-devel, currently), but my current
hurdle is that it can't find my root device (which is on sda1 on the
sata drive).
This is probably a silly error in my kernel's .config, but I can't
figure out what's missing. The boot log ends with:
[ 1.199004] mmcblk0: mmc0:b368 244 MiB
[ 1.204422] mmcblk0: p1
[ 1.326049] ata1.00: ATA-8: WDC WD20NPVT-00Z2TT0, 01.01A01, max UDMA/133

[ 1.399368] Kernel panic - not syncing: VFS: Unable to mount root fs on
[...]
So, the SD card is properly found and its mbr partition is
correctly parsed. The sata drive is also found, but for some reason it
seems that the sda device is not created (and not parsed either, of
course).
I suspect this is not a sunxi-specific problem, but my.config clearly
has the required bits to read block devices, parsed MBR partition
tables, and find sata drives, and I can't find anything in the
menuconfig which would be required to plug them together.
Any hint anyone?
