setexpr: add regex substring matching and substitution

Add "setexpr name gsub r s [t]" and "setexpr name sub r s [t]"
commands which implement substring matching for the regular
expression <r> in the string <t>, and substitution of the string <s>.
The result is assigned to the environment variable <name>.  If <t> is
not supplied, the previous value of <name> is used instead.  "gsub"
performs global substitution, while "sub" will replace only the first
substring.

Both commands are closely modeled after the gawk functions with the
same names.

Examples:

- Generate broadcast address by substituting the last two numbers of
  the IP address by "255.255":

   => print ipaddr

=> setexpr broadcast sub "(.*\\.).*\\..*" "\\1255.255" $ipaddr
broadcast=192.168.255.255

- Depending on keyboard configuration (German vs. US keyboard) a
  barcode scanner may initialize the MAC address as C0:E5:4E:02:06:DC
  or as C0>E5>4E>02>06>DC.  Make sure we always have a correct value:

=> print ethaddr
ethaddr=C0>E5>4E>02>06>DC
=> setexpr ethaddr gsub > :
ethaddr=C0:E5:4E:02:06:DC

- Do the same, but substitute one step at a time in a loop until no
  futher matches:

=> setenv ethaddr C0>E5>4E>02>06>DC

> echo -----

Add SLRE - Super Light Regular Expression library

Downloaded from http://slre.sourceforge.net/
and adapted for U-Boot environment.

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).

Trigger generic board error only when building

At present the generic board error can occur when configuring U-Boot, or
during distclean, but this is incorrect. The existing autoconf.mk may come
from an earlier U-Boot configuration which is about to be overwritten.

Make the error conditional so that it will only be triggered when we are
actually building U-Boot.

This avoids a problem where the system is being reconfigured to remove
CONFIG_SYS_GENERIC_BOARD on an architecture that does not support it.

Tegra: Restore cp15 VBAR _start vector write for ARMv7

A start vector fix was added by AneeshV for OMAP4 (commit 0d479b53),
and caused the old monilithic Tegra builds to hang due to an undefined
instruction trap. Previously, the code needed to run on both the
AVP (ARM7TDI) and A9, and the AVP doesn't have a CP15 register.

ARM: tegra: support T33 SKU of Tegra30

Make U-Boot aware of the T33 SKU of Tegra30, and treat it identically
to any other Tegra30.

An alternative would be to simply remove the SKU checking from
tegra_get_chip_type(); most use of the value most likely simply wants
to know the current chip, not the specific SKU. Or, the function could
be split into separate tegra_get_chip() and tegra_get_sku() for the
cases where differentiation really is required.

I wonder whether tegra_get_chip_type() should printf() whenever any
unkown chip/SKU is found, although perhaps the function is called so
early that the printf() wouldn't actually make it to the UART anyway.

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
