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
ipaddr=192.168.1.104
=> 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
=> while setexpr ethaddr sub > :
> do
> echo -----
> done
ethaddr=C0:E5>4E>02>06>DC
-----
ethaddr=C0:E5:4E>02>06>DC
-----
ethaddr=C0:E5:4E:02>06>DC
-----
ethaddr=C0:E5:4E:02:06>DC
-----
ethaddr=C0:E5:4E:02:06:DC
-----
C0:E5:4E:02:06:DC: No match
=> print ethaddr
ethaddr=C0:E5:4E:02:06:DC
etc.

Simplify the argument checking for the "setexpr" command. This is

ethaddr=00:10:ec:00:c5:15
- print all variables that have at least 2 colons in their value:
=> env grep -v -e :.*:

This allows write of files from the host filesystem in sandbox. There is
currently no concept of overwriting the file and removing its existing
contents - all writing is done on top of what is there. This means that
writing 10 bytes to the start of a 1KB file will only update those 10
bytes, not truncate the file to 10 byte slong.
If the file does not exist it is created.

With sandbox it is tricky to add an FDT to the image at build time (or

of sandbox.
Sandbox can read files directly from the host, though, so add an option

since such flash programming errors usually are detected earlier
while unprotecting/erasing/programming. Please only enable

In common/cmd_nvedit.c, en env_print(), the wrong type is used for len.
hexport_r() returns -1 on error (like OOM), which is converted to
0xffffffff when put in an unsigned. Said value is obviously bigger then
0, and as a result an uninitialized string is then displayed. Other
usages of hexport_r() in the code correctly uses ssize_t to keep its

Currently x86 has its own means of managing the global data and board data
(bd_t), and this code resides in start.S. With generic board, we need to
ensure that we leave this alone - i.e. don't clear it as we do on other
archs.
This fixes a problem where the memory init data is cleared which causes
the video driver to operate very slowly.
Signed-off-by: Simon Glass <sjg@chromium.org>
The intention of the memory init code is that it should work the same with
CONFIG_SYS_GENERIC_BOARD and without. This is tricky because dram_init()
is called prior to relocation with generic board (matching other archs)
and after relocation without generic board.
Adjust the init sequence so that dram_init() is not called in the generic
board case, which seems like the easiest fix for now. Also ensure that
relocation addresses are still calculated.

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

We make these two functions take a size_t pointer to how much space
was used on NAND to read or write the buffer (when reads/writes happen)
so that bad blocks can be accounted for. We also make them take an
loff_t limit on how much data can be read or written. This means that
we can now catch the case of when writing to a partition would exceed
the partition size due to bad blocks. To do this we also need to make
check_skip_len count not just complete blocks used but partial ones as
well. All callers of nand_(read|write)_skip_bad are adjusted to call
these with the most sensible limits available.
