Subject: [PATCH 1/6 v10] ARM: Add basic architecture support for
VIA/WonderMedia 85xx SoC's
This adds support for the family of Systems-on-Chip produced initially
by VIA and now its subsidiary WonderMedia that have recently become
widespread in lower-end Chinese ARM-based tablets and netbooks.
Support is included for both VT8500 and WM8505, selectable by a
configuration switch at kernel build time.
Included are basic machine initialization files, register and
interrupt definitions, support for the on-chip interrupt controller,
high-precision OS timer, GPIO lines, necessary macros for early debug,
pulse-width-modulated outputs control, as well as platform device
configurations for the specific drivers implemented elsewhere.

Welcome the jubilee tenth revision of this patch ;-)
I've tried to incorporate the suggestions by Ryan and Arnd, hope that
there is nothing left out. There was a massive reorganization of code
to remove less-than-obvious magic with MMIO registers and irqs being
held in huge structs, now they are again macro definitions. Those
macros are, however, only included in single isolated files, and
actual values to use are chosen at runtime by calling the respective
routines at machine initialization. There are also stylistic changes
all around, where Ryan suggested.
As a result, i8042 should again be adjusted a bit to reflect the new
place to find respective register/irq definitions, that one will be
sent in the respective thread shortly.
Best regards,
Alexey
