Subject: Re: [PATCH] ARM: mach-moxart: platform port for MOXA ART SoC
Hi,
.. it's been a while ..
This is now rebased for 3.10 and DT thanks to help from #armlinux on
Freenode. It should tick the boxes in the list from Arnd.
I'm only posting changes in arch/arm/* and will continue submitting
drivers separately as requested, this applies to next-20130515.
The full repository is available @
https://code.google.com/p/linux-3-9-rc3-moxart/source/list
Note: no boot without clocksource and irqchip drivers (I'll submit
these separately to the correct maintainers).
Also it won't boot without reverting the following commit:
e651eab0af88aa7a281fe9e8c36c0846552aa7fc - "ARM: 7677/1: LPAE: Fix
mapping in alloc_init_section for unaligned addresses"
Best regards,
Jonas
