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.

The omap1_defconfig this should be eventually usable for booting

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.

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 the recent changes to core ARM kernel code, we can now
boot SMP kernel on UP systems. Update omap3_defconfig to
enable SMP. This allows us to remove omap_4430sdp_defconfig.
In addition to enabling SMP, we also need to disable some
options to make the system boot:
- For some reason LOCK_STAT causes tons of
WARNING: at mm/percpu-vm.c:320 pcpu_alloc+0x2fc/0x888()
so disable it for now.
- MUSB init fails for multi-omap, disable it for now.
- LOCAL_TIMERS hangs on omap4, disable it for now.
Also disable DEBUG_LL as this should be only enabled for
debugging.
