This delay applies to any data transfer on I2C bus.
For example 1kB data read with per-byte access (which happens if
environment is stored in I2C EEPROM) takes more than 10 seconds.
Moreover data bus driver has to care about bus state and data transfer,
but not about internal states of attached devices.

The endless waiting for a bit to be set can cause a hang, add a timeout
so we prevent such situation. A testcase for such a hang is below. The
testcase assumes a device to be present at address 0x50 and a device to
NOT be present at address 0x42 . Also note that the "sleep 1" induced
delays are imperative for this bug to manifest .
i2c read 0x42 0x0.2 0x10 0x42000000 ; sleep 1 ; \
i2c read 0x50 0x0.2 0x10 0x42000000 ; sleep 1 ; \
i2c read 0x42 0x0.2 0x10 0x42000000
The expected result of the above command is:
Error reading the chip.
Error reading the chip.
While without this patch, we observe a hang in the last read from 0x42
precisely when waiting for this bit to be set.

Current implementation only supports 8 bit word lengths, even though
omap3 can handle anything between 4 and 32.
Update the spi interface to support changing the SPI word length,
and implement it in omap3_spi driver to support the full range of
possible word lengths.
This implementation is backwards compatible by defaulting to the old
behavior of 8 bit word lengths.
Also, it required a change to the omap3_spi non static I/O functions,
but since they are not used anywhere else, no collateral changes are required.

If no softreset save registers are found on the hardware
"bootcount" is stored in the environment. To prevent a
saveenv on all reboots, the environment variable
"upgrade_available" is introduced. If "upgrade_available" is
0, "bootcount" is always 0 therefore no need to save the
environment on u-boot boot, if "upgrade_available" is 1 "bootcount"
is incremented in the environment and environment gets written
on u-boot start.
So the Userspace Applikation must set the "upgrade_available"
and "bootcount" variable to 0 (for example with fw_setenv),
if a boot was successfully.

This also applies to two files which are not listed

include/configs/omap4_common.h conflicts are due to
the OMAP4 conversion to ti_armv7_common.h on the ARM

Resolution is to convert as this icludes removal of

Without setting up the PIRQ[A:D] interrupt routes, PCI interrupts will
be left disabled. Linux does not set up this routing but relies upon it
having been set up by the bootloader, reading back the IRQ lines which
the PIRQ[A:D] signals have been routed to.
This patch routes PIRQA & PIRQB to IRQ 10, and PIRQC & PIRQD to IRQ 11.
This matches the setup used by YAMON.

Malta boards may be used with cores which support L2 caches, however
U-boot does not yet support L2 cache for MIPS. Thus for the moment we'll

This patch adds support for running on Malta boards using coreFPGA6
core cards, including support for the msc01 system controller used
with them. The system controller is detected at runtime allowing one
U-boot binary to run on a Malta with either.
Due to the PCI I/O base differing between Maltas using gt64120 & msc01
system controllers, the UART setup is modified slightly. A second UART
is added so that there is one pointing at the correct address for each
system controller. The Malta board then defines its own
default_serial_console function to select the correct one at runtime.
The incorrect UART will simply not function.
Tested on:
- A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both
with and without an L2 cache.
- QEMU.

On relatively slow boards (such as the MIPS Malta with an FPGA core
card) it can be extremely common for transmits to underflow - to the
point where it appears they simply do not work at all. Setting the
NOUFLO bit causes the ethernet controller to not begin transmission on
the wire until a transmit start point is reached. Setting that transmit
start point to the full packet will cause the controller to only
transmit the packet once it has buffered it entirely thus preventing any
transmit underflows from occuring and allowing the controller to
function on slower boards.

Ensure that the view of memory from the CPU & the ethernet controller is
coherent at the various points where they exchange data. This prevents
stale data from being transmitted or received, and prevents the driver
from getting stuck waiting for the ethernet controller to update
descriptors when in reality it has but the old values are being read
from cache.
