[PATCH] m32r: framebuffer device support
This patch is for supporting Epson s1d13xxx framebuffer device for m32r. #
Sorry, a little bigger.
The Epson s1d13806 is already supported by 2.6.12 kernel, and its driver is
placed as drivers/video/s1d13xxxfb.c.
For the m32r, a header file include/asm-m32r/s1d13806.h was prepared for
several m32r target platforms. It was originally generated by an Epson
tool S1D13806CFG.EXE, and modified manually for the m32r platforms.
