Yes, of course. I patched your Git kernel and after that I compiled it
again. U-Boot loads the kernel and the dtb file. Then the kernel starts but
it doesn't find any hard disks (partitions).
Interesting. Does it find the storage controller (what kind of
storage does it use?).
It seems not. I don't see any infos about hard disks in the kernel ring
buffer. The two serial ATA (SATA 2.0) controllers are integrated in the
P5020 SoC and the hard disks are connected via SerDes lanes (PCIe) to
the SoC. LANE 16 = SATA 0 and LANE 17 = SATA 1.
For the PASEMI board can you test the attached patch? Also are you
using Compact Flash cards on that system?
Yes, we are using Compact Flash cards. The slot is wired to the CPU
local bus. It works with your kernel. :-)
Where is the attached patch?
I downloaded the version 5 of your Git kernel and compiled it today.
Unfortunately the PASEMI ethernet doesn't work.

@All
Could you please also test Christoph's kernel on your PASEMI and NXP boards? Download:
'git clone git://git.infradead.org/users/hch/misc.git -b powerpc-dma.5 a'
Thanks,
Christian
