of_partition: devfs_add_partition returns an error pointer ...

Check for the return value of devfs_add_partition with IS_ERR.
Otherwise we dereference a NULL pointer when devfs_add_partition
fails.

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.

drop CONFIG_PARTITION_NEED_MTD ...

With CONFIG_PARTITION_NEED_MTD enabled we use mtd rather than devfs
directly to create partitions on mtd devices. Since:

The bad block aware device creation doesn't work if this option
is disabled. With this we remove CONFIG_PARTITION_NEED_MTD and always
use mtd partitions on mtd devices.

net cpsw: fix rx stability under heavy network load ...

RX DMA Head Descriptor Pointer can get 0 when there is a lot of traffic,
which results in a timeout error. A good way to provoke this error is by
sending lots of ARP requests. This patch makes sure that the RX DMA Head
Descriptor Pointer is set.

The origin driver, from which this is derived, already contains this fix.
