* libfdt: Add fdt_next_subnode() to permit easy subnode iterationSimon Glass2013-05-14-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* "env grep" - add support for regular expression matchesWolfgang Denk2013-05-01-3/+26
| | | | | | | | | | | | | | | | | | | | | | | | | 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 ethaddr=00:10:ec:00:c5:15 ver=U-Boot 2013.04-rc1-00289-g497746b-dirty (Mar 22 2013 - 12:50:25) etc. Signed-off-by: Wolfgang Denk <wd@denx.de>
* Add SLRE - Super Light Regular Expression libraryWolfgang Denk2013-05-01-0/+725
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* hashtable: preparations to use hexport_r() for "env grep"Wolfgang Denk2013-05-01-8/+24
| | | | | | | | | | 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.

* crc32: Correct endianness of crc32 resultSimon Glass2013-04-19-1/+4
| | | | | | | | | | | | | | | | | | | 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.

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 Signed-off-by: Che-Liang Chiou <clchiou@chromium.org>

* | Roll crc32 into hash infrastructureSimon Glass2013-02-28-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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). Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Signed-off-by: Allen Martin <amartin@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
