This patch is essentially an update of u-boot MTD subsystem to
the state of Linux-3.7.1 with exclusion of some bits:
- the update is concentrated on NAND, no onenand or CFI/NOR/SPI
flashes interfaces are updated EXCEPT for API changes.
- new large NAND chips support is there, though some updates
have got in Linux-3.8.-rc1, (which will follow on top of this patch).
To produce this update I used tag v3.7.1 of linux-stable repository.
The update was made using application of relevant patches,
with changes relevant to U-Boot-only stuff sticked together
to keep bisectability. Then all changes were grouped together
to this patch.

Iterating through subnodes with libfdt is a little painful to write as we
need something like this:
for (depth = 0, count = 0,
offset = fdt_next_node(fdt, parent_offset, &depth);
(offset >= 0) && (depth > 0);
offset = fdt_next_node(fdt, offset, &depth)) {
if (depth == 1) {
/* code body */
}
}
Using fdt_next_subnode() we can instead write this, which is shorter and
easier to get right:
for (offset = fdt_first_subnode(fdt, parent_offset);
offset >= 0;
offset = fdt_next_subnode(fdt, offset)) {
/* code body */
}
Also, it doesn't require two levels of indentation for the loop body.

This patch adds the bitrev library from the linux kernel. This is a simple
algorithm that uses an 8 bit look-up table to reverse the bits in data types of
8, 16, or 32 bit widths. The docg4 nand flash driver uses it.

When CONFIG_REGEX is enabled, the new option "-e" becomes available
which causes regular expression matches to be used. This allows for
example things like these:
- print all MAC addresses:
=> env grep -e eth.*addr
eth1addr=00:10:ec:80:c5:15
ethaddr=00:10:ec:00:c5:15
- print all variables that have at least 2 colons in their value:
=> env grep -v -e :.*:
addip=setenv bootargs ${bootargs} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:${netdev}:off
panic=1
eth1addr=00:10:ec:80:c5:15

Downloaded from http://slre.sourceforge.net/
and adapted for U-Boot environment.
Used to implement regex operations on environment variables.
Code size is ~ 3.5 KiB on PPC.
To enable this code, define the CONFIG_REGEX option in your board
config file.
Note: There are more recent versions of the SLRE library available at
http://slre.googlecode.com ; unfortunately, the new code has a heavily
reorked API which makes it less usable for our purposes:
- the return code is strings, which are more difficult to process
- we don't get any information any more which sub-string of the data
was matched by the given regex
- it is much more cumbersome to work with arbitrary expressions, where
for example the number of substrings for capturing are not known at
compile time
Also, there does not seem to be any real changes or improvements of
the functionality.
Because of this, we deliberately stick with the older code.
Note 2: the test code (built when SLRE_TEST is defined) was modified
to allow for more extensive testing; now we can test the regexp
matching on all lines on a text file (instead of the whole data in the
file as a single block).

The output of "env grep" is unsorted, and printing is done by a
private implementation to parse the hash table. We have all the
needed code in place in hexport_r() alsready, so let's use this
instead. Here we prepare the code for this, without any functional
changes yet.

When crc32 is handled by the hash library, it requires the data to be in
big-endian format, since it reads it byte-wise. Thus at present the 'crc32'
command reports incorrect data. For example, previously we might see:
Peach # crc32 40000000 100
CRC32 for 40000000 ... 400000ff ==> 0d968558
but instead with the hash library we see:
Peach # crc32 40000000 100
CRC32 for 40000000 ... 400000ff ==> 5885960d
Correct this.

TPM command library implements a subset of TPM commands defined in TCG
Main Specification 1.2 that are useful for implementing secure boot.
More TPM commands could be added out of necessity.
You may exercise these commands through the 'tpm' command. However, the
raw TPM commands are too primitive for writing secure boot in command
interpreter scripts; so the 'tpm' command also provides helper functions
to make scripting easier.
For example, to define a counter in TPM non-volatile storage and
initialize it to zero:
$ tpm init
$ tpm startup TPM_ST_CLEAR
$ tpm nv_define d 0x1001 0x1
$ tpm nv_write d 0x1001 0
And then increment the counter by one:
$ tpm nv_read d 0x1001 i
$ setexpr.l i $i + 1
$ tpm nv_write d 0x1001 $i

The kernel states:
---8<---
The OMAP3 GPMC hardware BCH engine computes remainder polynomials, it does not
provide automatic error location and correction: this step is implemented using
the BCH library.
--->8---
And we do so in u-boot.
This implementation uses the same layout for BCH8 but it is fix. The current
provided layout does only work with 64 Byte OOB.

T114 has a slightly different I2C clock, with a new (extra) divisor
in standard/fast mode and HS mode. Tested on my Dalmore, and the I2C
clock is 100KHz +/- 3Hz on my Saleae Logic analyzer.
Added a new entry in compat_names for T114 I2C since it differs
from the previous Tegra SoCs. A flag is set when T114 I2C HW is
found so new features like the extra clock divisor can be used.

Add the CRC32 algorithm to the list of available hashes, and make
the crc32 command use hash_command(). Add a new crc32_wd_buf() to
make this possible, which puts its result in a buffer rather than
returning it as a 32-bit value.
Note: For some boards the hash command is not enabled, neither
are sha1, sha256 or the verify option. In this case the full
hash implementation adds about 500 bytes of overhead. So as a
special case, we use #ifdef to select very simple bahaviour in
that case. The justification for this is that it is currently
a very common case (virtually all boards enable crc32 but only
some enable more advanced features).

Add driver for tegra SPI "SLINK" style driver. This controller is
similar to the tegra20 SPI "SFLASH" controller. The difference is
that the SLINK controller is a genernal purpose SPI controller and the
SFLASH controller is special purpose and can only talk to FLASH
devices. In addition there are potentially many instances of an SLINK
controller on tegra and only a single instance of SFLASH. Tegra20 is
currently ths only version of tegra that instantiates an SFLASH
controller.
This driver supports basic PIO mode of operation and is configurable
(CONFIG_OF_CONTROL) to be driven off devicetree bindings. Up to 4
devices per controller may be attached, although typically only a
single chip select line is exposed from tegra per controller so in
reality this is usually limited to 1.
To enable this driver, use CONFIG_TEGRA_SLINK

Move all the C runtime setup code from every start.S
in arch/arm into arch/arm/lib/crt0.S. This covers
the code sequence from setting up the initial stack
to calling into board_init_r().
Also, rewrite the C runtime setup and make functions
board_init_*() and relocate_code() behave according to
normal C semantics (no jumping across the C stack any
more, etc).
Some SPL targets had to be touched because they use
start.S explicitly or for some reason; the relevant
maintainers and custodians are cc:ed.
