Merge samsung, imx, tegra into u-boot-arm/master
This commit merges branches from samsung, imx and tegra
meant to fix merge issues between u-boot/master and
u-boot-arm/master, as well as a few manual merge fixes.
In e1000e driver, Rx descriptor queue is used such that hardware can add only
one descriptor at a time. So the WTHRESH granularity in RXDCTL should be set
to single descriptor. This would ensure that every time controller fills a Rx
descriptor, it is flushed to host memory. Earlier this granularity was in
cache line units i.e 2 descriptors. This leads to controller always waiting
for 2 descriptors before flushing them out. But since not more than one Rx BD
is actually available , the accumulation condition never gets hit.

can take the number of page to be written as an argument. nand_update_full
is passing the size (in bytes) to nand write.raw. This value was previously
ignored but now breaks the write.
- this patch updates the default environment of these boards to provide a

It could happen (1 out of 100 times) that NAND did not start up correctly after
warm rebooting, so we end up with various failures or DMA timed out due to a
stalled BCH. When resetting BCH together with GPMI, the issue could not be
observed anymore (after 10000+ reboots). We probably need the consistent state
already before sending commands to NAND. This behaviour was observed in barebox
and kernel, so I assume it affects U-Boot as well. I chose to keep the extra
reset for BCH when changing the flash layout to be on the safe side.

designware_i2c: Fixed the setting of the i2c bus speed
There are three couple (hcnt/lcnt) of registers for each
speed (SS/FS/HS). The driver needs to set the proper couple
of regs according to what speed we are setting.
In the newer versions of designware i2c IP there is the possibility
of configuring it with IC_EMPTYFIFO_HOLD_MASTER_EN=1, which basically
requires the s/w to generate the stop bit condition directly, as
the h/w will not automatically generate it when TX_FIFO is empty.
To avoid generation of an extra 0x0 byte sent as data, the
IC_STOP command must be sent along with the last IC_CMD.
This patch always writes bit[9] of ic_data_cmd even in the
older versions, assuming that it is a noop there.
