74a18ee8a5 crc32: Correct endianness of crc32 result
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.

8732b0700d tpm: Add TPM command library
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.

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.

d20a40de9d Roll crc32 into hash infrastructure
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).

b19f57491a tegra: add SPI SLINK driver
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

d266f66925 lib/vsprintf.c: don't special-case pointers to address null
The %p format of printf() would print a pointer to address null as
"(null)".  This makes sense in a real OS where a NULL pointer must
never be dereferenced, but this is a bootloader, and there are cases
where accessing the data at address null makes perfect sense.

Remove the special case in lib/vsprintf.c using "#if 0" with a comment
to make clear this was an intentional change and to stop re-adding
this code.

c71b64f361 libfdt: Add helper function to create a trivial, empty tree
The libfdt read/write functions are now usable enough that it's become a
moderately common pattern to use them to build and manipulate a device
tree from scratch.  For example, we do so ourself in our rw_tree1 testcase,
and qemu is starting to use this model when building device trees for some
targets such as e500.

However, the read/write functions require some sort of valid tree to begin
with, so this necessitates either having a trivial canned dtb to begin with
or, more commonly, creating an empty tree using the serial-write functions
first.

This patch adds a helper function which uses the serial-write functions to
create a trivial, empty but complete and valid tree in a supplied buffer,
ready for manipulation with the read/write functions.

7ac2fe2da2 OMAP: networking support for SPL
This patch adds support for networking in SPL. Some devices are
capable of loading SPL via network so it makes sense to load the
main U-Boot binary via network too. This patch tries to use
existing network code as much as possible. Unfortunately, it depends
on environment which in turn depends on other code so SPL size
is increased significantly. No effort was done to decouple network
code and environment so far.

This is needed for the SPEAr SPL support, as SPEAr uses the mkimage

99e139d590 net: use common rand()/srand() functions
Replace rand() with the functions from lib/. The link-local network code
stores its own seed, derived from the MAC address. Thus making it
independent from calls to srand() in other modules.

7b6e80538b lib/powerpc: addrmap_phys_to_virt() should return a pointer
addrmap_phys_to_virt() converts a physical address (phys_addr_t) to a
virtual address, so it should return a pointer instead of an unsigned long.
Its counterpart, addrmap_virt_to_phys(), takes a pointer, so now they're
orthogonal.

The only caller of addrmap_phys_to_virt() converts the return value to
a pointer anyway.

6642a681e4 tegra: Add tegra keyboard driver
Add support for internal matrix keyboard controller for Nvidia Tegra
platforms. This driver uses the fdt decode function to obtain its key
codes.

Support for the Ctrl modifier is provided. The left and right ctrl keys are
dealt with in the same way.

This uses the new keyboard input library (drivers/input/input.c) to decode
keys and handle most of the common input logic. The new key matrix library
is also used to decode (row, column) key positions into key codes.

The intent is to make this driver purely about dealing with the hardware.

Key detection before the driver is loaded is supported. This key will be
picked up when the keyboard driver is initialized.

Modified by Bernie Thompson <bhthompson@chromium.org> and
Simon Glass <sjg@chromium.org> for device tree, input layer, key matrix
and various other things.
