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.

The DMA code in sunxi_mmc.c is broken. mmc_trans_data_by_dma() allocates the
dma descriptors on the stack, and then exits while the dma transfer is in
progress, so the dma engine is reading stack memory which at that point may
be re-used. So far we've gotten away with this by luck, but recent u-boot
changes have shifted the stack start address by 16 bytes, which combined
with dma alignment now exposes this problem.
Since we end up just busy waiting for the dma engine anyway, this commit
fixes things by simply removing the dma code, resulting in smaller bug-free
code.

The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF
images and u-boot, and does this for virtual platforms by using
semihosting. This commit extends this idea by allowing u-boot to also
use semihosting to load the kernel/ramdisk/dtb. This eliminates the need
for a bootwrapper and produces a more realistic boot sequence with
virtual models.
Though the semihosting code is quite generic, support for armv7 in
fastmodel is less useful due to the wide range of available silicon
and the lack of a free armv7 fastmodel, so this change contains an
untested armv7 placeholder for the service trap opcode.

In a very few cases we need to adjust the driver model root device, such as

Signed-off-by: Simon Glass <sjg@chromium.org>
When debugging drivers it is useful to see what I/O accesses were done
and in what order.
Even if the individual accesses are of little interest it can be useful to
verify that the access pattern is consistent each time an operation is
performed. In this case a checksum can be used to characterise the operation
of a driver. The checksum can be compared across different runs of the
operation to verify that the driver is working properly.
In particular, when performing major refactoring of the driver, where the
access pattern should not change, the checksum provides assurance that the
refactoring work has not broken the driver.
Add an I/O tracing feature and associated commands to provide this facility.
It works by sneaking into the io.h heder for an architecture and redirecting
I/O accesses through its tracing mechanism.
For now no commands are provided to examine the trace buffer. The format is
fairly simple, so 'md' is a reasonable substitute.
Note: The checksum feature is only useful for I/O regions where the contents
do not change outside of software control. Where this is not suitable you can
fall back to manually comparing the addresses. It might be useful to enhance
tracing to only checksum the accesses and not the data read/written.

During bootm/z, U-Boot relocates the DTB and initrd to high memory so
they are out of the way of the kernel. On ARM at least, some parts of
high memory are "highmem" and can't be accessed at early boot. To solve
this, we need to restrict this relocation process to use lower parts of
RAM that area accessible.
For the DTB, an earlier patch of mine set CONFIG_SYS_BOOTMAPSZ. However,
since some platforms have different restrictions on DTB and initrd
location, that config option doesn't affect the initrd. We need to set
the initrd_high environment variable to control the initrd relocation.
Since we have carefully chosen the load addresses for the DTB and
initrd (see comments in include/configs/tegraNNN-common.h re: values in
MEM_LAYOUT_ENV_SETTINGS), we don't actually need any DTB or initrd
relocation at all. Skipping relocation removes some redundant work.
Hence, set both fdt_high and initrd_high to ffffffff which completely
disables relocation.
If the user does something unusual, such as using custom locations for
the DTB/initrd load address or wanting to use DTB/initrd relocation for
some reason, they can simply set these variables to custom values to
override these environment defaults.

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
connected to it. Also, dynamic detection of NAND bus-width from on-chip ONFI
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

As per following Sections in ONFI Spec, GET_FEATURES and SET_FEATURES also need
byte-addressing on 16-bit devices.
*Section: Target Initialization"
"The Read ID and Read Parameter Page commands only use the lower 8-bits of the
data bus. The host shall not issue commands that use a word data width on x16
devices until the host determines the device supports a 16-bit data bus width
in the parameter page."
*Section: Bus Width Requirements*
"When the host supports a 16-bit bus width, only data is transferred at the
16-bit width. All address and command line transfers shall use only the lower
8-bits of the data bus. During command transfers, the host may place any value
on the upper 8-bits of the data bus. During address transfers, the host shall
set the upper 8-bits of the data bus to 00h."
So porting following commit from linux kernel

As per following Sections in ONFI Spec, NAND_CMD_READID should use only
lower 8-bit for transfering command, address and data even on x16 NAND device.
*Section: Target Initialization"
"The Read ID and Read Parameter Page commands only use the lower 8-bits of the
data bus. The host shall not issue commands that use a word data width on x16
devices until the host determines the device supports a 16-bit data bus width

*Section: Bus Width Requirements*
"When the host supports a 16-bit bus width, only data is transferred at the

on the upper 8-bits of the data bus. During address transfers, the host shall
set the upper 8-bits of the data bus to 00h."
Thus porting following commit from linux-kernel to ensure that column address
is not altered to align to x16 bus when issuing NAND_CMD_READID command.
commit 3dad2344e92c6e1aeae42df1c4824f307c51bcc7
mtd: nand: force NAND_CMD_READID onto 8-bit bus
Author: Brian Norris <computersforpeace@gmail.com> (preserving authorship)
The NAND command helpers tend to automatically shift the column address
for x16 bus devices, since most commands expect a word address, not a
byte address. The Read ID command, however, expects an 8-bit address
(i.e., 0x00, 0x20, or 0x40 should not be translated to 0x00, 0x10, or
0x20).
This fixes the column address for a few drivers which imitate the
nand_base defaults.

Switch to an SPL image. The SPL for Ventana does the following:
- setup i2c and read the factory programmed EEPROM to obtain DRAM config
and model for board-specific calibration data
- configure DRAM per CPU/size/layout/devices/calibration
- load u-boot.img from NAND and jump to it
This allows for a single SPL+u-boot.img to replace the previous multiple boa
configurations.

This is a workaround for 32 bit hardware limitation of TDM.
T1040 has 36 bit physical addressing, TDM DMAC register
are 32 bit wide but need to store address of CCSR space
which lies beyond 32 bit address range. This workaround
creats a LAW to enable access of TDM DMA to CCSR by
mapping CCSR to overlap with DDR.
A hole of 16M is created in memory using device tree. This
workaround law is set only if "tdm" is defined in hwconfig.
Also disable POST tests and add LIODN for TDM

Now that we wait the correct specification-mandated time at the end of
usb_hub_power_on(), I suspect that CONFIG_USB_HUB_MIN_POWER_ON_DELAY has
no purpose.
For cm_t35.h, we already wait longer than the original MIN_POWER_ON_DELAY,
so this change is safe.
For gw_ventana.h, we will wait as long as the original MIN_POWER_ON_DELAY
iff pgood_delay was at least 200ms. I'm not sure if this is the case or
not, hence I've CC'd relevant people to test this change.
