The csarX and cscrX registers in the fbcs_t struct are 16-bit for
CONFIG_M5235 and 32-bit wide otherwise. The code in cpu_init.c
accessed them always as 32-bit, effectively creating a wrong memory
access on M5235. Fixed that by choosing out_be16/out_be32 depending
on whether CONFIG_M5235 is defined or not.

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.
Refer to the commit: 10a37fd7a4 for details of device & partition string.

J6 EVM can be built with UART3 as console, but currently
there's nothing muxing UART3 correctly. Likely this only
works because, based on commit log, author was only testing
with UART3 boot and - I assume - ROM code leave UART3 correctly
muxed in that case.
If we want to boot from MMC and still use UART3 as console,
then we need to mux those signals correctly.

In current gpio_set_value() implementation, it always sets the gpio control bit
no matter the value argument is 0 or 1. Thus the GPIOs never set to low.
This patch fixes this bug.
The address bus is used as a mask on read/write operations, so that independent
software drivers can set their GPIO bits without affecting any other pins in a
single write operation. Thus we don't need a read-modify-write to update the
register.

firmware. First, the MC GCR register is set to 0 to reset all cores. MC
firmware and DPL images are copied from their location in NOR flash to
DDR. MC registers are updated with the location of these images.
Deasserting the reset bit of MC GCR register releases core 0 to run.
Core 1 will be released by MC firmware. Stop bits are not touched for
this step. U-boot waits for MC until it boots up. In case of a failure,
device tree is updated accordingly. The MC firmware image uses FIT format.

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.
Please refer to doc/README.semihosting for a more detailed description
of semihosting and how it is used with the armv8 virtual platforms.

The Tegra I2C controller's TX FIFO contains 32-bit words. If the final
FIFO entry of a transaction contains fewer than 4 bytes, the driver
currently fills the unused FIFO bytes with uninitialized data. This can
be confusing when reading back the FIFO content for debugging purposes.
Solve this by explicitly initializing the variable containing FIFO data
before filling it (partially) with data. With this change,
send_recv_packets()'s loop's if (is_write) code mirrors the else (i.e.
read) branch.

I2C read transactions are typically implemented as follows:

However, Tegra's I2C driver currently implements reads as follows:
START(write) address STOP START(read) data... STOP
This sequence confuses at least the AS3722 PMIC on the Jetson TK1 board,
leading to corrupted read data in some cases. Fix the driver to chain
the transactions together using repeated starts to solve this.
