pcm051: Enable DDR PHY dynamic power down bit

This is done already for am335x in
59dcf970d11ebff5d9f4bbbde79fda584e9e7ad4 and also applies for pcm051.

It powers down the IO receiver when not performing read which helps
reducing the overall power consuption in low power states
(suspend/standby).

omap3_beagle: Flush UART3 xmit on enable if TEMT is broken

Flush UART3 xmit on enable if TEMT is broken

On some OMAP3 devices when UART3 is configured for boot mode before SPL starts
only THRE bit is set. We have to empty the transmitter before initialization
starts. This patch avoids the use of CONFIG_SYS_NS16550_BROKEN_TEMT.

omap_gpmc: change nandecc command

With uppcoming BCH support on OMAP devices we need to decide between differnt
algorithms when switching the ECC engine.  Currently we support 1-bit hammign
and 8-bit BCH on HW backend.

In order to switch between differnet ECC algorithms we need to change the
interface of omap_nand_switch_ecc() also.

omap_gpmc: add support for hw assisted BCH8

The kernel states:

---8<---
The OMAP3 GPMC hardware BCH engine computes remainder polynomials, it does not
provide automatic error location and correction: this step is implemented using
the BCH library.
--->8---

And we do so in u-boot.

This implementation uses the same layout for BCH8 but it is fix. The current
provided layout does only work with 64 Byte OOB.

omap2420-h4: Fix DRAM initialisation

The size of the DRAM for the omap2420-h4 board is getting setup in the
dram_init() function. However, for the current u-boot release this is
too late and needs to be done in dram_init_banksize(). Therefore, add
a dram_init_banksize() function for the omap2420-h4 board and setup the
DRAM size there.

omap2420-h4: Fix booting from NOR flash

The omap2420-h4 board is using a RAM based address as the linker
location for code. This is causing several problems when attempting
to run the latest u-boot code base on this board from flash. Update
the default linker location for code to be in NOR flash. Please note
that OMAP maps the NOR flash to address 0x08000000 by default and so
use this as the default address for the NOR flash.

Also remove legacy code that attempts to calculate where in flash the
sdata structure, that holds the memory interface configuration data,
is located. By changing the default linker location for code to flash
this is no longer necessary.

While booting with dt blob, if fdt_high is not set to

omap5: Allow use of a plain text env file

For production systems it is better to use script images since
they are protected by checksums and carry valuable information
like name and timestamp. Also, you can't validate the content
passed to env import.

But for development, it is easier to use the env import command and
plain text files instead of script-images.

Since both OMAP5evm/uevm boards are used primarily for development,
we allow U-Boot to load env var from a text file in case that an
boot.scr script-image is not present.

The variable uenvcmd (if existent) will be executed (using run) after
uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
will be started.
