ARM: am335x bone: Fix Booting from eMMC ...

Booting a beaglebone black from eMMC is broken since:

    ARM: AM335x: Beaglebone: Use stripped down devicetree for MLO

The stripped down device tree does not have the eMMC device node which
the beaglebone black needs for booting. Add this node to the common dts
file, but keep it disabled. It gets enabled later with a call to
am33xx_of_register_bootdevice() when the system is booted from eMMC.

ARM: AM335x: Beaglebone: Use stripped down devicetree for MLO ...

The beaglebone white and black have different devicetrees. Both
get linked into the MLO which makes it too big. Use a devicetree
generated from am335x-bone-common.dtsi which both board variants
can share. This reduces the binary size by about 30k.

serial: imx: Fix buggy transmissions when baudrate mismatches ...

Bit 7 of UCR3 is described in the i.MX reference manuals (with the exception
of i.MX1) as follows:

ADNIMP: Autobaud Detection Not Improved-. Disables new features of
	autobaud detection (See Baud Rate Automatic Detection
	Protocol, for more details).

	0 Autobaud detection new features selected
	1 Keep old autobaud detection mechanism

The "new features" mechanism occasionally causes the receiver to get out of sync
and continuously produces received characters of '0xff'.

In order to reproduce the problem:

$ cs0.baudrate=19200
- Change the terminal baudrate to 19200
- Type in the console and it should look good
- Change the terminal baudrate back to 115200
- Type 'b' in the console, then a stream of '0xff' is transmitted in loop

Setting the ADNIMP bit avoids the transmission of '0xff' in loop.

Also rename the bit definition as per the reference manual.

Tested on mx6q.

Based on a patch from Eric Nelson for U-boot.

mtd: nand: mxs: Fix 2k nand with oob size of 224 bytes ...

The mxs nand driver has a calculation for the ecc strength.
This calculation was not used for some common nands and it
was assumed that 2k page nands always have a ecc strength
of 8. This is not true since there are devices with 224 bytes
of oob instread of 64 bytes. These allow for a greater ecc
strength. Since the kernel relies on the calculation and
we have to be consistent with the kernel use the calculcation
in barebox aswell and just remove our assumptions.

Subject: [PATCH] Fix the options and protocols used by the loadx command.

It seems like the loadx command was improperly copy/pasted from the loady
implementation, and was trying to load files using the ymodem protocol. This
patch should fix the command so that it uses xmodem, implements the -t option
and outputs the correct baudrate being used.
