With the omap-serial the device has changed from ttyS to ttyO as
the system may have both omap-serial and 8250 ports.
Note that systems using omap-serial need to be updated to use ttyO[012]
instead of ttyS[012] in the bootloader, CONFIG_CMDLINE, /etc/inittab,
and the root file system with mknod. Also you may need to add ttyO[012]
to /etc/securetty.

Disable CPUfreq since
1) is not yet supported in mainline, and
2) the current driver fails to suspend properly

In working towards a smaller default kernel, only devices used for
early boot should be built in. Toward that end, build the following
as modules by default:
- bluetooth
- audio: ALSA, ASoC
- WLAN

This patch addresses below things
- Renaming existing omap3_defconfig which has OMAP2, OMAP3 and OMAP4 builds
enabled to more appropriate name 'omap2plus_defconfig'
- L1 cache shift is suppose to be 5 on OMAP4 where as it is 6 on previous
OMAPs. Keeping it to 5 is safer option for OMAP4 and previous OMAPs. For
OMAP3 only build the shift would be still 6
- Enable needed Errata's for OMAP4 to work with DMA based device drivers
CONFIG_PL310_ERRATA_588369=y
CONFIG_ARM_ERRATA_720789=y
- Enable the Micrel ethernet controller
CONFIG_KS8851=y
CONFIG_KS8851_MLL=y
With above three changes, OMAP4 ethernet, mmc etc works reliably.
