This patch uses generic 'load' command instead of 'fatload' for 'loadbootscript' and 'loadbootenv' as already done for 'loadimage' and 'loaduimage' for OMAP4 boards.
This allows to use EXT partition instead of FAT, while keeping FAT compatibility.

Define CONFIG_SYS_FSL_ESDHC_ADDR using USDHC4_BASE_ADDR.
USDHC3 and USDHC4 are both initialized in board_mmc_init. There is

This is an implementation of GPIOs for Tegra that uses driver model. It has
been tested on trimslice and also using the new iotrace feature.
The implementation uses a top-level GPIO device (which has no actual GPIOS).
Under this all the banks are created as separate GPIO devices.
The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7,
..., Z0..Z7, AA0..AA7, etc.
Since driver model is not yet available before relocation, or in SPL, a
special function is provided for seaboard's SPL code.

This patch adds support for parallel NOR device (S29GL512S10) present on J6-EVM.
The Flash device is connected to GPMC controller on chip-select[0] and accessed
as memory-mapped device. It has data-witdh=x16, capacity-64MBytes(512Mbits) and
is CFI compatible.
As multiple devices are share GPMC pins on this board, so following board
settings are required to detect NOR device:
SW5.1 (NAND_BOOTn) = OFF (logic-1)
SW5.2 (NOR_BOOTn) = ON (logic-0) /* Active-low */
SW5.3 (eMMC_BOOTn) = OFF (logic-1)
SW5.4 (QSPI_BOOTn) = OFF (logic-1)
And also set appropriate SYSBOOT configurations:
SW3.1 (SYSBOOT[ 8])= ON (logic-1) /* selects SYS_CLK1 speed */
SW3.2 (SYSBOOT[ 9])= OFF (logic-0) /* selects SYS_CLK1 speed */
SW3.3 (SYSBOOT[10])= ON (logic-1) /* wait-pin monitoring = enabled */
SW3.4 (SYSBOOT[11])= OFF (logic-0) /* device type: Non Muxed */
SW3.5 (SYSBOOT[12])= OFF (logic-0) /* device type: Non Muxed */
SW3.6 (SYSBOOT[13])= ON (logic-1) /* device bus-width: 1(x16) */
SW3.7 (SYSBOOT[14])= OFF (logic-0) /* reserved */
SW3.8 (SYSBOOT[15])= ON (logic-1) /* reserved */
Also, following changes are required to enable NOR Flash support in
dra7xx_evm board profile:
This patch adds support for NAND device connected to GPMC chip-select on
following AM43xx EVM boards.
am437x-gp-evm: On this board, NAND Flash signals are muxed with eMMC, thus at a
time either eMMC or NAND can be enabled. Selection between eMMC and NAND is
controlled by:
(a) Statically using Jumper on connecter (J89) present on board.
(a) If Jumper on J89 is NOT used, then selection can be dynamically controlled
by driving SPI2_CS0[MUX_MODE=GPIO] pin via software:
SPI2_CS0 == 0: NAND (default)
SPI2_CS0 == 1: eMMC
am43x-epos-evm: On this board, NAND Flash control lines are muxed with QSPI,
Thus only one of the two can be used at a time. Selection is controlled by:
(a) Dynamically driving following GPIO pin from software
GPMC_A0(GPIO) == 0 NAND is selected (default)
NAND device (MT29F4G08AB) on these boards has:
- data-width=8bits
- blocksize=256KB
- pagesize=4KB
- oobsize=224 bytes
For above NAND device, ROM code expects the boot-loader to be flashed in BCH16
ECC scheme for NAND boot, So by default BCH16 ECC is enabled for AM43xx EVMs.

Enable DFU protocol support (via the "dfu" command) on Tegra boards where
USB device/gadget mode is enabled.
Note that for DFU to operate correctly on Tegra, we still need some DFU
fixes/enhancements that are going through the DFU -> USB trees. However,
the code builds just fine without those changes, and applying this patch
now will allow both sets of patches to meet in the main U-Boot tree much
more quickly.
In order to run test/dfu/dfu_gadget_test.sh, you would need to add the
following to the board configuration:
CONFIG_EXT4_WRITE
CONFIG_CMD_EXT4_WRITE
However, I haven't enabled those here, since I believe the main use-case
for DFU on Tegra is raw flash writing, rather than filesystem access, so
we don't need the additional code-size hit. However, I could be persuaded
otherwise! We should probably add a separate test script for raw flash
access.

Replace the custom $bootcmd with that from <config_distro_bootcmd.h>.
There should be no functional change, since the new generic $bootcmd was

The #defines to enable/disable U-Boot commands/features were moved

Fixes commit a0a37183bd
ARM: omap: merge GPMC initialization code for all platform
1) NAND device are not directly memory-mapped to CPU address-space, they are
indirectly accessed via following GPMC registers:
- GPMC_NAND_COMMAND_x
- GPMC_NAND_ADDRESS_x
- GPMC_NAND_DATA_x
Therefore from CPU's point of view, NAND address-map can be limited to just
above register addresses. But GPMC chip-select address-map can be configured
in granularity of 16MB only.
So this patch uses GPMC_SIZE_16M for all NAND devices.
2) NOR device are directly memory-mapped to CPU address-space, so its
address-map size depends on actual addressable region in NOR FLASH device.
So this patch uses CONFIG_SYS_FLASH_SIZE to derive GPMC chip-select address-map
size configuration.

The Keystone SoCs use the same NAND driver as Davinci.
This patch adds opportunity to write Keystone U-boot image to NAND
device using appropriate RBL ECC layout. This is needed only if RBL
boots U-boot from NAND device and that's supposed that raw u-boot
partition is used only for writing image.
The main problem is that default Davinci ECC layout is different from
Keystone RBL layout. To read U-boot image the RBL needs that image was
written using RBL ECC layout.
The BBT table is written using default Davinci layout and has to
be updated using one. The BBT can be updated only while erasing
chip or by forced bad block assigning, so erase function has to
use native ecc layout in order to be able to write BBT correctly.
So if we're writing to NAND U-boot address we use RBL layout for
others we use default ECC layout.
Also remove definition for CONFIG_CMD_NAND_ECCLAYOUT as there is no
reasons to use ECC layout commands. It was added by mistake.

At present stdio device functions do not get any clue as to which stdio
device is being acted on. Some implementations go to great lengths to work
around this, such as defining a whole separate set of functions for each
possible device.
For driver model we need to associate a stdio_dev with a device. It doesn't
seem possible to continue with this work-around approach.
Instead, add a stdio_dev pointer to each of the stdio member functions.
Note: The serial drivers have the same problem, but it is not strictly
necessary to fix that to get driver model running. Also, if we convert
serial over to driver model the problem will go away.

TQMa6 is a family of modules based on Freescale i.MX6. It consists of
TQMa6Q (i.MX6 Quad), TQMa6D (i.MX6 Dual) featuring eMMC, and 1 GiB DDR3
TQMa6S (i.MX6 Solo) featuring eMMC and 512 MiB DDR3
The modules need a baseboard. Initially the MBa6x starterkit mainboard is
supported. To easy support for other mainboards the functionality is splitted
in one file for the module (tqma6.c) and one file for the baseboard (tqma6_
mba6).
The modules can be boot from eMMC (on USDHC3) and SPI flash.
The following features are supported:
- MMC: eMMC on module (on USDHC3) and SD-card (on MBa6x mainboard)
- Ethernet: RGMII using micrel KSZ9031 phy on MBa6x mainboard for TQMa6<x> module.
The phy needs special configurations for the pad skew registers to adjust for
the signal routing.
Also support for standard ethernet commands and uppdate via tftp.
- SPI: ECSPI1 with bootable serial flash on module and two additional
chip selects on MBa6x
- I2C: This patch adds support for the I2C busses on the TQMa6<x> modules (I2C3)
and MBa6x baseboards (I2C1). The LM75 temperature sensors on TQMa6<x> and MBa6x

Similar to the USB NIC found on OMAP5uEVM, PandaBoard and BeagleBoard-XM
boards, the sunxi SoCs have a NIC onboard without an embedded MAC address.
Just like the omap used on these boards, the sunxi SoCs do have a unique chip
id, in the form of the 128 bit SID register:
http://linux-sunxi.org/SID_Register_Guide
So mimick the BeagleBoard-XM board code (commit 548a64d8) and use the chip id
to generate a unique fixed MAC address.
We check for the SID not being all 0, since some early A20 batches
shipped without having there SID programmed.
Note we use specific parts of the 128 bits, since some parts indicate the
SoC family / revision, and thus are fixed. The algorithm for this was taken
from the linux-sunxi.org kernels.

Use get_device_and_partition() is better since:
1. It will call the device initialize function internally. So we can
remove the mmc intialization code to save many lines.
2. It is used by fatls/fatload/fatwrite. So saveenv & load env should
use it too.
3. It can parse the "D:P", "D", "D:", "D:auto" string to get correct
device and partition information by run-time.
Also we remove the FAT_ENV_DEVICE and FAT_ENV_PART. We use a string:
FAT_ENV_DEVICE_AND_PART.
For at91sam9m10g45ek, it is "0". That means use device 0 and if:
a)device 0 has no partition table, use the whole device as a FAT file
system.
b)device 0 has partittion table, use the partition #1.
