lzma: Update LZMA SDK code from 9.20 to 25.01

2026-01-06T20:44:21Z

Currently, we have a copy of the LZMA SDK code, version 9.20, with small updates. The original import of the LZMA SDK included a script to update the library. This is no longer possible, due to important local changes, so remove it. We also remove a number of extra text files that should be unchanged from upstream, but provide no direct value to the project. Instead, have the help text for LZMA note that this comes from the LZMA SDK. Next, we move our code up to the current release, 25.01. There are a number of new header files, and some performance improvements made to the code, at the cost of between 2 to 3 kilobytes in binary size. As there is now a Kconfig option to disable this and retain similar speed to what we have currently, the default option is to make this trade-off. Our changes to the code around calling schedule() to avoid the watchdog being triggered are kept. We add __UBOOT__ guards in two places to prevent conflict with our own usage of these words on MIPS.

Drop all duplicate newlines. No functional change. Signed-off-by: Marek Vasut

lib: Remove inclusion from these files

2023-12-21T13:54:37Z

After some header file cleanups to add missing include files, remove common.h from all files in the lib directory. This primarily means just dropping the line but in a few cases we need to add in other header files now. Reviewed-by: Simon Glass Signed-off-by: Tom Rini

lzma: Fix decompression speed regression

2023-07-14T19:21:08Z

Uncompressing a 1.7Mbytes FIT image on U-boot 2023.04 takes approx 7s on a powerpc 8xx. The same on U-boot 2023.07-rc6 takes approx 28s unless watchdog is disabled. During that decompression, LzmaDec_DecodeReal() calls schedule 1.6 million times, that is every 4µs in average. In the past it used to be a call to WATCHDOG_RESET() which was just calling hw_watchdog_reset(). But the combination of commit 29caf9305b6 ("cyclic: Use schedule() instead of WATCHDOG_RESET()") and commit 26e8ebcd7cb ("watchdog: mpc8xxx: Make it generic") results in an heavier processing. However, there is absolutely no point in calling schedule() that often. By moving and keeping only one call to schedule() in the main loop the number of calls is reduced to 1.2 million which is still too much. So add logic to only call schedule every 1024 times. That leads to a call to schedule approx every 6ms which is still far enough to entertain the watchdog which has a 1s timeout on powerpc 8xx. powerpc 8xx being one of the slowest targets we have today in U-boot, and most other watchdogs having a timeout of one minutes instead of one second like the 8xx, this fix should not have negative impact on other targets.

cyclic: Use schedule() instead of WATCHDOG_RESET()

2022-09-18T08:26:33Z

Globally replace all occurances of WATCHDOG_RESET() with schedule(), which handles the HW_WATCHDOG functionality and the cyclic infrastructure. Signed-off-by: Stefan Roese Reviewed-by: Simon Glass Tested-by: Tom Rini [am335x_evm, mx6cuboxi, rpi_3,dra7xx_evm, pine64_plus, am65x_evm, j721e_evm]

lzma: update to lzma sdk 9.20

2012-12-06T20:56:38Z

Updated code taken from latest lzma sdk release 9.20 at http://downloads.sourceforge.net/sevenzip/lzma920.tar.bz2 This generates quite a lot of checkpatch warnings, but I guess we need to keep the code style as is to avoid a massive job each time we update this.

Rename lib_generic/ to lib/

2010-04-13T07:13:04Z

Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser
