2010-03-21env: fix endian ordering in crc tableJeff Angielski
The crc table was being built as little endian for big endian targets. This would cause fw_printenv to always fail with "Warning: Bad CRC, using default environment" messages. Signed-off-by: Jeff Angielski <jeff@theptrgroup.com> Acked-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
2010-01-26gzip/zlib: make features optionalMike Frysinger
If you really want to slim down U-Boot and you would rather use a higher compression scheme (like LZMA), it'd be nice to disable gzip/zlib since these code bases take up a significant amount of space. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-01-17Make getenv_IPaddr() globalDirk Behme
There are boards out there that do not have network support in U-Boot (CONFIG_CMD_NET not set), but they do so in Linux. This makes it desirable to be able to port network configuration (like the IP address) to the Linux kernel. We should not make the passing of the IP configuration to Linux dependent on U-Boot features / settings. For this, make getenv_IPaddr() global. This fixes build error u-boot/lib_xxx/board.c:360: undefined reference to `getenv_IPaddr' on various architectures.

2009-12-21move prototypes for gunzip() and zunzip() to common.hWolfgang Wegner
Prototype for gunzip/zunzip was only in lib_generic/gunzip.c and thus repeated in every file using it. This patch moves the prototypes to common.h and removes all prototypes distributed anywhere else. Signed-off-by: Wolfgang Wegner <w.wegner@astro-kom.de>

2009-12-07zlib.c: avoid build conflicts for cradle boardWolfgang Denk
Commit dce3d79710 updated the zlib code to v0.95; this caused conflicts when building for the "cradle" board, because the (pretty generic) preprocessor variable "OFF" was used in multiple files. Make sure to avoid further conflicts by #undef'ing it in zlib.c before redefining it.

2009-12-05lzma: ignore unset filesizesMike Frysinger
The Linux kernel build system changed how it compresses things with LZMA such that the header no longer contains the filesize (it is instead set to all F's). So if we get a LZMA image that has -1 for the 64bit field, let's just assume that the decompressed size is unknown and continue on. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-05zlib: Optimize decompressionJoakim Tjernlund
This patch optimizes the direct copy procedure. Uses get_unaligned() but only in one place. The copy loop just above this one can also use this optimization, but I havn't done so as I have not tested if it is a win there too. On my MPC8321 this is about 17% faster on my JFFS2 root FS than the original. No speed test has been performed in u-boot. Size increase on ppc: 484 bytes Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se> Acked-by: Peter Korsgaard <jacmet@sunsite.dk>
2009-12-05add lzop decompression supportPeter Korsgaard
Add lzop decompression support to the existing lzo bitstream handling (think gzip versus zlib), and support it for uImage decompression if CONFIG_LZO is enabled. Lzop doesn't compress as good as gzip (~10% worse), but decompression is very fast (~0.7s faster here on a slow ppc). The lzop decompression code is based on Albin Tonnerre's recent ARM Linux lzo support patch. Cc: albin.tonnerre@free-electrons.com Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2009-12-05Generic udelay() with watchdog supportIngo van Lil
According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset. This patch adds a generic udelay() function which takes care of resetting the watchdog before calling an architecture-specific __udelay(). Signed-off-by: Ingo van Lil <inguin@gmx.de>
2009-12-02crc32: Impl. linux optimized crc32()Joakim Tjernlund
Ported over the more efficient linux crc32() function. A quick comparsion on ppc: After changing the old crc32 to do 4 bytes in the inner loop to be able to compare with new version one can note: - old inner loop has 61 insn, new has 19 insn. - new crc32 does one 32 bit load of data to crc while the old does four 8 bits loads. - size is bit bigger for the new crc32: 1392(old) 1416(new) of text. The is because the new version shares code with crc32_no_comp() instead of duplicating code. - about 33% faster on ppc: New > crc 0 0xfffffff -> 39 secs Old > crc 0 0xfffffff -> 60 secs Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>

2009-08-11zlib: add watchdog reset callGiuseppe CONDORELLI
This patch adds watchdog reset call to allow its invokation during decompression phase. This control was present on old zlib version and here it is backported for those relevant routines.

Shove a lot of the HOSTCC and related #ifdef checking crap into the new compiler.h header so that we can keep all other headers nice and clean.

2009-07-16Remove legacy NAND and disk on chip code.Scott Wood
Legacy NAND had been scheduled for removal. Any boards that use this were already not building in the previous release due to an #error. The disk on chip code in common/cmd_doc.c relies on legacy NAND, and it has also been removed. There is newer disk on chip code in drivers/mtd/nand; someone with access to hardware and sufficient time and motivation can try to get that working, but for now disk on chip is not supported.

2009-04-30lib_generic: gunzip: New function zunzipRicardo Ribalda Delgado
Separate gunzip in gunzip: Find the end of the header and call zunzip. zunzip: Inflate gunzip block without header. UBI fs blocks can be compresed in lzo, zlib or no-compression. The current implementation of u-boot supported all the compressions but there was a bug in the implementation of the zlib blocks. UBIFS's Zlib blocks do not have header but they were compressed using gunzip, a function used to decompress gunzip files/sectors with a header. This patch adds a new function zunzip that uncompress a zlib block with no header. Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@uam.es>

2009-03-20Add LZO decompressor supportStefan Roese
This patch adds LZO decompression support to U-Boot. It is needed for the upcoming UBIFS support, since UBIFS uses LZO as default compressor/ decompressor. Since we only support read-only in UBIFS, only the decompressor is needed. All this is copied with minor changes from the current Linux kernel version (2.6.28-rc8). This patch only implements this LZO decompressor support for PPC. Other platforms using UBIFS will have to add the required "include/asm/unaligned.h" as well. It should be fairly easy to copy this from the Linux source tree as I have done it for PPC in this patch. Signed-off-by: Stefan Roese <sr@denx.de>
2009-03-20vsprintf: pull updates from Linux kernelMike Frysinger
This brings in support for the %p modifier which allows us to easily print out things like ip addresses, mac addresses, and pointers. It also converts the rarely used 'q' length modifier to the common 'L' modifier when dealing with quad types. While this new code is a bit larger (~1k .text), most of it should be made up by converting the existing ip/mac address code to use format modifiers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-01-27Fix gunzip in case of insufficient output bufferMatthias Fuchs
U-Boot's gunzip() function does not handle the return code of zlib's inflate() function correctly. gunzip() is implemented to uncompress all input data in one run. So the correct return code for the good case is Z_STREAM_END. In case of insufficient output buffer memory inflate returns Z_OK. For gunzip() this is an error. It also makes sense to me to call inflateEnd() also in case of an error. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd-electronics.com>

2008-11-19UBI: Add basic UBI support to U-Boot (Part 6/8)Kyungmin Park
This patch adds basic UBI (Unsorted Block Image) support to U-Boot. It's based on the Linux UBI version and basically has a "OS" translation wrapper that defines most Linux specific calls (spin_lock() etc.) into no-ops. Some source code parts have been uncommented by "#ifdef UBI_LINUX". This makes it easier to compare this version with the Linux version and simplifies future UBI ports/bug-fixes from the Linux version.
