Add basic OMAP2 chip support.
Add the OMAP242x (arm1136 core) initialisation with basic on-chip peripherals and update OMAP1 peripherals which are re-used in OMAP2. Make palmte.c and sd.c errors go to stderr. Allow disabling SD chipselect. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4213 c046a42c-6fe2-441c-8c8c-71466251a162
