Log:
[ARMLLB]: Split up support between OMAP3 Beagle and ZOOM2.
[ARMLLB]: Implement ZOOM2 ARMLLB board support package. TWL4030 read/write implemented
(through basic I2C on the HS interface), RTC and Keypad Matrix implemented (through
TWL4030), NEC WVGA Panel Initialization (through basic SPI interface on the MBPSI), basic
clock setup and GPIO access for DSS/DISPC, setup DSS/DISPC for output on the NEC panel.
UART implemented through Quad-UART NS16550 compatible chip (using CPORTlib).
[ARMLLB]: Requires having been booted through x-loader+uboot as a kernel image. Will work
on directly booting from NAND later.
