[PATCH] SharpSL: Add new ARM PXA machines Spitz and Borzoi with partial Akita Support
Add the platform support code for two new Sharp Zaurus Models, Spitz
(SL-C3000) and Borzoi (SL-C3100).
This patch also adds most of the foundations for Akita (SL-C1000) Support.
The missing link for Akita is the driver for its I2C io expander. Once this
has been finished, the missing Kconfig option and machine declaration can
easily be added to this code.
