[PATCH 1/6 v9] ARM: Add basic architecture support for VIA/WonderMedia 85xx SoC's

Alexey Charkov alchark at gmail.com
Mon Dec 20 14:54:24 EST 2010


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.

Signed-off-by: Alexey Charkov <alchark at gmail.com>

Dropped GENERIC_TIME selection from Kconfig. No further changes
compared to v8.

This is against current Linus' 'master' branch.

Best regards,
Alexey
