lib: import bitrev library from the linux kernel

2013-05-05T21:47:04Z

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. [port from linux kernel v3.9 commit 7ee32a6d30d1c8a3b7a07a6269da8f0a08662927] [originally added: v2.6.20 by commit a5cfc1ec58a07074dacb6aa8c79eff864c966d12] Signed-off-by: Mike Dunn

lib: consolidate hang()

Delete all occurrences of hang() and provide a generic function. Signed-off-by: Andreas Bießmann Acked-by: Albert ARIBAUD [trini: Modify check around puts() in hang.c slightly] Signed-off-by: Tom Rini

Add SLRE - Super Light Regular Expression library

2013-05-01T20:24:00Z

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).

tpm: Add TPM command library

2013-04-12T21:13:13Z

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 Signed-off-by: Che-Liang Chiou

omap_gpmc: add support for hw assisted BCH8

2013-04-08T15:29:05Z

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.

Introduce a basic initcall implementation

2013-03-15T20:13:59Z

This library supports calling a list of functions one after the other. It is intended that we move to a more powerful initcall implementation as proposed by Graeme Russ . For now, this allows us to do the basics. Signed-off-by: Simon Glass

Make linux kernel string funcs available to tools

2012-12-13T18:46:07Z

isspace() and strim() are not in the typical user-mode string.h, so put them in a separate compilation unit so that they can be built into tools that need them independent of the other common string functions. This allows code shared by u-boot and the linux user-mode tools to link. Signed-off-by: Joe Hershberger

Introduce arch_phys_memset which works like memset but on physical memory

2012-12-06T22:30:40Z

The default implementation of this function is just memset, but other implementations will be needed when physical memory isn't accessible by U-Boot using normal addressing mechanisms. Signed-off-by: Gabe Black Signed-off-by: Che-Liang Chiou Signed-off-by: Simon Glass

ARM: prevent misaligned array inits

2012-10-15T18:53:07Z

Under option -munaligned-access, gcc can perform local char or 16-bit array initializations using misaligned native accesses which will throw a data abort exception. Fix files where these array initializations were unneeded, and for files known to contain such initializations, enforce gcc option -mno-unaligned-access. Signed-off-by: Albert ARIBAUD [trini: Switch to usign call cc-option for -mno-unaligned-access as Albert had done previously as that's really correct] Signed-off-by: Tom Rini
