ARM: tegra: fix Ventana standalone build

Ventana always pulls in files from the Seaboard directory, so needs to
mkdir $(obj)../seaboard unconditionally. This fixes:

git clean -f -d -x
./MAKEALL ventana

"MAKEALL -s tegra20" passes without this change, because Seaboard
happens to be built before Ventana, and hence the directory has already
been created.

I believe the mkdir is only needed for out-of-tree builds, since the
seaboard directory is part of the source tree. However, since we always
build an SPL for Tegra now, which I believe is effectively an out-of-tree
build, we will always need this at some time. The overhead of just
uncondtionally executing the mkdir is minimal, and simplifies the
Makefile, since we don't need to code up the exact minimal condition to

MX28: SPI: Fix the DMA chaining

It turns out that in order for the SPI DMA to properly support
continuous transfers longer than 65280 bytes, there are some very
important parts that were left out from the documentation.

Firstly, the XFER_SIZE register is not written with the whole length
of a transfer, but is written by each and every chained descriptor
with the length of the descriptors data buffer.

Next, unlike the demo code supplied by FSL, which only writes one PIO
word per descriptor, this does not apply if the descriptors are chained,
since the XFER_SIZE register must be written. Therefore, it is essential
to use four PIO words, CTRL0, CMD0, CMD1, XFER_SIZE. CMD0 and CMD1 are
written with zero, since they don't apply. The DMA programs the PIO words
in an incrementing order, so four PIO words.

Finally, unlike the demo code supplied by FSL, the SSP_CTRL0_IGNORE_CRC
must not be set during the whole transfer, but it must be set only on the
last descriptor in the chain.

mw 0x42000000 0 0x4000 ; sf probe ; sf read 0x42000000 0x0 0x10000 ; sha1sum 0x42000000 0x10000

The SHA1 checksum was correct during the first call. Yet with
every subsequent call of the above command, it differed and was
wrong.

It turns out this was because of a race condition. On the first
time the command was called, no cacheline contained any data from
the destination memory location. The DMA transfered data into the
location and the cache above the location was invalidated. Then the
checksum was computed, but that meant the data were loaded into data
cache.

On any subsequent call, the DMA again transfered data into the same
destination. Yet during the transfer, some of the DCache lines were
evicted and written back into the main memory. Once the DMA transfer
completed, the data cache was invalidated over the memory location as
usual. But the data that were to be loaded back into the data cache
by subsequent SHA1 checksuming were corrupted.

tegra: put eMMC environment into the boot sectors

When I set up Tegra's config files to put the environment into eMMC, I
assumed that CONFIG_ENV_OFFSET was a linearized address relative to the
start of the eMMC device, and spanning HW partitions boot0, boot1,
general* and the user area in order. However, it turns out that the
offset is actually relative to the beginning of the user area. Hence,
the environment block ended up in a different location to expected and
documented.

Set CONFIG_SYS_MMC_ENV_PART=2 (boot1) to solve this, and adjust
CONFIG_ENV_OFFSET to be relative to the start of boot1, not the entire
eMMC.

  there is no display support
* board_eth_init is implemented such that it does not cause U-Boot to
  report an explicit failure ("CPU Net Initialization Failed").

Since Ethernet is implemented via USB (fixed on Smarttop, pluggable on
Smartbook, and handled by "usb start") - the warning that is left
("No ethernet found") is perfectly reasonable at the point it is printed

Offsets of the fields after removed bi_ip_addr are wrong,

shows that bi_ip_addr is not accessed there. Adding bi_ip_addr
