6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

6f911492ed omap: Update omap2plus_defconfig to use ttyO instead ttyS
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.

7ad0e386d4 OMAP2+: defconfig: disable CPUfreq
Disable CPUfreq since

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

ecfdd76d2f OMAP2+: defconfig: modularize bluetooth, audio and WLAN
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

Uncompressed kernel size comparison:

We need to enable ARM_ERRATA_411920 for omap2 and
remove the omap2 specific defconfigs.

455d4d2dc7 omap: Update and rename common defconfig for omap2plus devices
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.
