[ARM] 3141/1: OMAP 1/5: Update omap1 specific files
Patch from Tony Lindgren
This patch syncs the mainline kernel with linux-omap tree.
The highlights of the patch are:
- Omap1 serial pport and framebuffer init updates by Imre Deak
- Add support for omap310 processor and Palm Tungsten E PDA
by Laurent Gonzales, Romain Goyet, et al. Omap310 and
omap1510 processors are now handled as omap15xx.
- Omap1 specific changes to shared omap clock framework
by Tony Lindgren
- Omap1 specific changes to shared omap pin mux framework
by Tony Lindgren
- Other misc fixes, such as update memory timings for smc91x,
omap1 specific device initialization etc.
