Bit 7 of UCR3 is described in the i.MX3x/i.MX5x/i.MX6x
reference manuals as follows:
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
On at least i.MX6DQ, i.MX6DLS and i.MX53, the "new features"
occasionally cause the receiver to get out of sync and
continuously produce received characters of '\xff'.
This patch disables the "new feature" on all boards, since
there's no support for auto-baud in U-Boot on any of them.
More details are available in this post on i.MX Community:

gd->bd->bi_baudrate is a copy of gd->baudrate.
Since baudrate is a common feature for all architectures,
keep gd->baudrate only.
It is true that bi_baudrate was passed to the kernel in that structure
but it was a long time ago.

k2hk EVM is based on Texas Instruments Keystone2 Hawking/Kepler
SoC. Keystone2 SoC has ARM v7 Cortex-A15 MPCore processor. Please
refer the ti/k2hk_evm/README for details on the board, build and other
information.
This patch add support for keystone architecture and k2hk evm.

It is useful for Cltl-C to be handled by U-Boot as it is on other boards.
But it is also useful to be able to terminate U-Boot with Ctrl-C.
Add an option to enable signals while in raw mode, and make this the
default. Add an option to leave the terminal cooked, which is useful for
redirecting output.

Add a simple LCD driver which uses SDL to display the image. We update the
image regularly, while still providing for reasonable performance.
Adjust the common lcd code to support sandbox.
For command-line runs we do not want the LCD to be displayed, so add a
--show_lcd option to enable it.

This is required for proper functionality on big-endian targets.
Memory-mapped registres of ARC UART are not 32-bit words but 8-bit bytes
so on little-endian target either acessor (_l or _b) works fine.
On big-endian only _b accessors works as expected.

The implementation of oc_serial_setbrg() for CONFIG_SYS_NIOS_FIXEDBAUD and
!CONFIG_SYS_NIOS_FIXEDBAUD are very similar.
Add a baudrate variable and set it to either CONFIG_BAUDRATE or gd->baudrate.
Then we can unify the code for both cases.
