This patch add support for BCH16_ECC to omap_gpmc driver.
*need to BCH16 ECC scheme*
With newer SLC Flash technologies and MLC NAND, and large densities, pagesizes
Flash devices have become more suspectible to bit-flips. Thus stronger
ECC schemes are required for protecting the data.
But stronger ECC schemes have come with larger-sized ECC syndromes which require
more space in OOB/Spare. This puts constrains like;
(a) BCH16_ECC can correct 16 bit-flips per 512Bytes of data.
(b) BCH16_ECC generates 26-bytes of ECC syndrome / 512B.
Due to (b) this scheme can only be used with NAND devices which have enough
OOB to satisfy following equation:
OOBsize per page >= 26 * (page-size / 512)

GPMC controller needs to be configured based on bus-width of the NAND device

parameters is not possible in following situations:
SPL: SPL NAND drivers does not support ONFI parameter reading.
U-boot: GPMC controller iniitalization is done in omap_gpmc.c:board_nand_init()
which is called before probing for devices, hence any ONFI parameter
information is not available during GPMC initialization.
Thus, OMAP NAND driver expected board developers to explicitely write GPMC
configurations specific to NAND device attached on board in board files itself.
But this was troublesome for board manufacturers as they need to dive into
lengthy platform & SoC documents to find details of GPMC registers and
appropriate configurations to get NAND device working.
This patch instead adds existing CONFIG_SYS_NAND_BUSWIDTH_16BIT to board config
hich indicates that connected NAND device has x16 bus-width. And then based on
this config GPMC driver itself initializes itself based on NAND bus-width. This
keeps board developers free from knowing GPMC controller specific internals.

ARM: tegra: enable USB device mode and UMS on some boards
For each of Jetson TK1, Venice2, and Beaver:
- Enable the first USB controller in DT, and describe its configuration.
- Enable USB device/gadget support. This allows the user to type e.g.
"ums 0 mmc 0" at the command-line to cause U-Boot to act a USB device
implementing the USB Mass Storage protocol, and expose MMC device 0
that way.
This allows a host PC to mount the Tegra device's MMC, partition it, and
install a filesystem on it.

Exynos: Make sure ps_hold gets set in the SPL
Setting ps_hold ought to be one of the first things we do when we
first boot up. If we wait until the main u-boot runs we won't set it
in time and the PMIC may power us back off.
