A20 support still needs a workaround under /sys/arch/arm/cortex/ which
i didn't include as i think support is still 'subtly' broken anyway..
And ahci is still not working for me, but there's a couple of
new drivers included.
Ethernet driver survived make build of userland with /usr/src mounted
via nfs, fwiw.
Now this is totally usable for me as-is already, so any feedback is
welcome, be it finding out possible bugs and/or confirming it's working.
Great work! I made a few changes to fix the timer code for the A20 CPU,
the diff to your code is attached. With this I am almost booting the
kernel on a cubieboard 2:

Here the output stops, I will look into that later. At this point I am
unable to figure out how to set the ethaddr in the u-boot version I am
using. setenv ethaddr xx:xx:xx:xx:xx:xx doesn't seem to have any effect.
Kind regards
Markus
Hi,
Thanks for the patch, it looks correct when compared to the user manual
and shows how ugly sources may get when not paid enough attention,
will fix the whitespaces there also. Note that Cortex-A7 should
support agtimer found in arch/arm/cortex, which would allow cleaning
up awtimer.c from the 'added on'-kind of hacks to support A20,
priorities have kept me from trying that one out so far.
To allow it to boot further you would have to change ICP_ADDR and
ICD_ADDR in ampintc, iirc. possibly 0x1000 and 0x2000 respectively,
which is not the fix that would ever get commited even if allwinner
would be on cvs, as it'll break Cortex-A9, and unfortunately, masking
by cpu is not working option either, there is example of where it would
fail already (exynos).
FDT is the only clean solution i can think of, when there is priority on
keeping arch/arm/cortex free of SoC-dependent code.
About ethaddr, have you tried pinging another host from u-boot?
Does your u-boot support emac? the one i initially downloaded for
cubieboard2 did not iirc., if you can boot the bsd.umg over network,
and still get 00:00:00:00:00:00, i will power up my cb2 to fix awe,
as it's so far untested on A20 afaik.

I'm going to commit the initial allwinner diff along with Martin's diff
tomorrow unless strong objection is raised.
This needs to be worked on intree instead of letting it rot on the mailinglist.
I got around 2,5k line diff to previous allwinner.tar.gz already.
It has the diff by Markus to fix timer on A20, besides major cleanup
on awtimer(mainly in _attach()) that definately should go in.
It has also ugly hacks to support ethernet&usb on Hackberry, possibly
doable in not so ugly way before FDT with boardids.
And dma controller usable as is likely to just ethernet driver,
which still has align issues with it so it's disabled there, and fixed
the ethernet to use second fifo on tx. possibly i forgot something.
I'll run a round of tests on what i have now once i've upgraded to
-current and mail it if i find no regressions, so i should
have it ready by tomorrow(i'll test by doing native kernel build).
