- DDR Training sequence happens very fast. The speedup in boot time is
negligible by skipping the training sequence during 2nd boot or after.
So remove the check and skip.
- This change improves the robustness of DDR training. If u-boot crashed
during DDR training, the training could be left in a limbo state, where
the BootROM has recorded that it is already in a 2nd boot. The training
must be repeated in this scenario to get out of this limbo state, but due
to the check it cannot be performed.

While R40 puts the EMAC syscon register at a different address from
other variants, the relevant portion of the register's layout is the
same. Factor out the register offset so the same code can be shared
by all variants. This matches what the Linux driver does.
This change provides two benefits beyond the simplification:
- R40 boards now respect the RX delays from the devicetree
- This resolves a warning on architectures where readl/writel
expect the address to have a pointer type, not phys_addr_t.

This code first figures out if there is an i2c,speeds property, if so
its size in u32s, and then reads the value into the local speeds[]
array. Both 'size' and 'speeds' are completely unused thereafter.
It's not at all clear what this is supposed to do. Of course, it could
be seen as a sanity check that the DT node does have an i2c,speeds
property with an appropriate number of elements, but for that one
wouldn't actually need to read it into speeds[]. Also, I can't find
anywhere else in the U-Boot code which makes use of values from that
property (this is is the only C code referencing "i2c,speeds"), so it
seems pointless to insist that it's there.

The default erase command applies on erase group unit, and

is not aligned to erase group size (e.g. erasing partition)
it causes unwanted erasing of the previous blocks, part of
the same erase group (e.g. owned by other logical partition,
or by the partition table itself).
To prevent this issue, a simple solution is to use TRIM as
argument of the Erase command, which is usually supported
with eMMC > 4.0, and allow to apply erase operation to write

On popular request make the display driver from T20 work on T30 as
well. Turned out to be quite straight forward. However a few notes
about some things encountered during porting: Of course the T30 device
tree was completely missing host1x as well as PWM support but it turns
out this can simply be copied from T20. The only trouble compiling the
Tegra video driver for T30 had to do with some hard-coded PWM pin
muxing for T20 which is quite ugly anyway. On T30 this gets handled by
a board specific complete pin muxing table. The older Chromium U-Boot
2011.06 which to my knowledge was the only prior attempt at enabling a
display driver for T30 for whatever reason got some clocking stuff
mixed up. Turns out at least for a single display controller T20 and
T30 can be clocked quite similar. Enjoy.

This patch makes use of union to alias Gen3 and more extensive Gen4

it is augmented with a more extensive PLL table and a valid MODEMR
