Since udev-182, udev no longer creates device nodes under /dev
and this has to be managed by the kernel devtmpfs filesystem.

This means that a kernel built with the current OMAP2+ config
will not boot on a system with a recent udev.

Also, it is good to have /dev automatically mounted since some
non-initramfs based setups assumes this and don't manually mount it.

    mmc: omap: remove private DMA API implementation

removed the private DMA API implementation from the OMAP mmc host to exclusively use the DMA engine API.

Unfortunately OMAP MMC and High Speed MMC host drivers don't support poll mode and only works with DMA.

Since omap2plus_defconfig doesn't enable this feature by default, the
following error is happens on an IGEPv2 Rev.C (and probably on most OMAP boards with MMC support):

[    2.199981] omap_hsmmc omap_hsmmc.1: unable to obtain RX DMA engine channel 48

The EHCI driver is not stable enough to be enabled by default.  In v3.5,
it has at least the following problems:

- warning dump during bootup
- hang during suspend
- prevents CORE powerdomain from entering retention during idle (even
  when no USB devices connected.)

This demonstrates that this driver has not been thoroughly tested and
therfore should not be enabled in the default defconfig.

In addition, the problems above cause new PM regressions which need be
addressed before this driver should be enabled in the default
defconfig.

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.

- Renaming existing omap3_defconfig which has OMAP2, OMAP3 and OMAP4 builds

- L1 cache shift is suppose to be 5 on OMAP4 where as it is 6 on previous

  OMAP3 only build the shift would be still 6

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

The bootloader on Nokia boards does not support updating

To mount root on n8x0, compile in also the MMC_OMAP.
It seems that the best way to mount root with the
new kernels on Nokia boards is to mount root on mmcblk0p2.

Note that n8x0 current has several issues booting with
omap3_defconfig: The bootloader has a 2MB limit for loading
kernels, so you may want to use kexec. Also ARMv6 does
not currently work with ARMv7 for VFP and TLS.

the number of modules is 8, down from 203. Build time also
scales proportionally.
