Hi Christoph,
I compiled kernels for the X5000 and X1000 from your branch
'powerpc-dma.6' today.
Gitweb:
http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/powerpc-dma.6
git clone git://git.infradead.org/users/hch/misc.git -b powerpc-dma.6 a
The X1000 and X5000 boot but unfortunately the P.A. Semi Ethernet
doesn't work.
Error messages (X1000):

Additionally, Xorg doesn't start on a virtual e5500 QEMU machine
anymore. I tested with the following QEMU command:
./qemu-system-ppc64 -M ppce500 -cpu e5500 -m 2048 -kernel
/home/christian/Downloads/vmlinux-5.0-rc4-3-AmigaOne_X1000_X5000/X5000_and_QEMU_e5500/uImage-5.0

Hi Christoph,
Thanks a lot for the updates. I will test the full branch tomorrow.

Hi Christoph,
I compiled kernels for the X5000 and X1000 from your new branch
'powerpc-dma.6-debug.2' today. The kernels boot and the P.A. Semi Ethernet
works!
Thanks for testing! I'll prepare a new series that adds the other
patches on top of this one.
And that was easier than I thought - we just had a few patches left
in powerpc-dma.6, so I've rebased that branch on top of
powerpc-dma.6-debug.2:
git://git.infradead.org/users/hch/misc.git powerpc-dma.6
Gitweb:
http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/powerpc-dma.6
I hope the other patches are simple enough, so just testing the full
branch checkout should be fine for now.
