- enable MMU -rework lcd frame buffer - add rtc/adc/power stubs (or not) - fix a few MMC related defines (hopefully) - implement cache handling for DMA - more SD work - add keymap (based on clip) - add virtual buttons - update linker scripts - big step toward apps actually compiling git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30200 a1c6a512-1295-4272-9138-f99709370657
