trace: Reduce the default for TRACE_EARLY_CALL_DEPTH_LIMIT

This is a silly value at present, since U-Boot's call depth never reaches 200. Fix it. Signed-off-by: Simon Glass

Bump LMB_MAX_REGIONS default to 16

2023-02-08T19:09:39Z

Since commit 06d514d77c37 ("lmb: consider EFI memory map") the EFI regions are also pushed into the lmb if EFI_LOADER is enabled (which is by default on most system). Which can cause the number of entries to go over the maximum as it's default is only 8. Specifically i ran into this case on an TI am62 which has an fdt with 4 reserved regions (in practice 3 lmb entries due to adjecent ranges). As this is likely to impact more devices bump the default max regions to 16 so there is a bit more slack.

Revert "lmb: Default to not-LMB_USE_MAX_REGIONS"

2023-02-08T15:18:26Z

As explained by Philippe Schenker, I was misinterpreting what happened in the case where we do not set LMB_USE_MAX_REGIONS and so had re-introduced the problem I was attempting to more widely resolve. This reverts commit 007ae5d108a37564905ea1588cb279f3a522cc3d. Reported-by: Philippe Schenker Signed-off-by: Tom Rini

lmb: Default to not-LMB_USE_MAX_REGIONS

2023-02-06T17:07:18Z

The LMB code allows for picking a hard limit on the number of regions it can know of, or to dynamically allocate these regions. The reason for this choice is to allow for the compiler to perform a size optimization in the common case. This optimization however, is very small, ranging from 196 bytes to 15 bytes saved, or in some cases, being larger. Now that we also have more regions covered by LMB (in order to protect various parts of our self at run time), the default of 8 is also much easier to hit and leads to non-obvious error messages (which imply that an area is protected, not that we're out of areas to add to the list). Switch to the dynamic use as the default. Signed-off-by: Tom Rini

lib: zstd: update to latest Linux zstd 1.5.2

2023-01-19T00:04:17Z

Update the zstd implementation to match Linux zstd 1.5.2 from commit 2aa14b1ab2. This was motivated by running into decompression corruption issues when trying to uncompress files compressed with newer versions of zstd. zstd users also claim significantly improved decompression times with newer zstd versions which is a side benefit. Original zstd code was copied from Linux commit 2aa14b1ab2 which is a custom-built implementation based on zstd 1.3.1. Linux switched to an implementation that is a copy of the upstream zstd code in Linux commit e0c1b49f5b, this results in a large code diff. However this should make future updates easier along with other benefits[1]. This commit is a straight mirror of the Linux zstd code, except to: - update a few #include that do not translate cleanly - linux/swab.h -> asm/byteorder.h - linux/limits.h -> linux/kernel.h - linux/module.h -> linux/compat.h - remove assert() from debug.h so it doesn't conflict with u-boot's assert() - strip out the compressor code as was done in the previous u-boot zstd - update existing zstd users to the new Linux zstd API - change the #define for MEM_STATIC to use INLINE_KEYWORD for codesize - add a new KConfig option that sets zstd build options to minify code based on zstd's ZSTD_LIB_MINIFY[2]. These changes were tested by booting a zstd 1.5.2 compressed kernel inside a FIT. And the squashfs changes by loading a file from zstd compressed squashfs with sqfsload. buildman was used to compile test other boards and check for binary bloat, as follows: > $ buildman -b zstd2 --boards dh_imx6,m53menlo,mvebu_espressobin-88f3720,sandbox,sandbox64,stm32mp15_dhcom_basic,stm32mp15_dhcor_basic,turris_mox,turris_omnia -sS > Summary of 6 commits for 9 boards (8 threads, 1 job per thread) > 01: Merge branch '2023-01-10-platform-updates' > arm: w+ m53menlo dh_imx6 > 02: lib: zstd: update to latest Linux zstd 1.5.2 > aarch64: (for 2/2 boards) all -3186.0 rodata +920.0 text -4106.0 > arm: (for 5/5 boards) all +1254.4 rodata +940.0 text +314.4 > sandbox: (for 2/2 boards) all -4452.0 data -16.0 rodata +640.0 text -5076.0 [1] https://github.com/torvalds/linux/commit/e0c1b49f5b674cca7b10549c53b3791d0bbc90a8 [2] https://github.com/facebook/zstd/blob/f302ad8811643c428c4e3498e28f53a0578020d3/lib/libzstd.mk#L31 Signed-off-by: Brandon Maier [trini: Set ret to -EINVAL for the error of "failed to detect compressed" to fix warning, drop ZSTD_SRCSIZEHINT_MAX for non-Linux host tool builds] Signed-off-by: Tom Rini

Revert "fdtdec: drop needlessly convoluted CONFIG_PHANDLE_CHECK_SEQ"

2023-01-18T18:49:13Z

The fdt_path_offset() function is slow since it must scan the tree. This substantial overhead now applies to all boards. The original code may not be ideal but it is fit for purpose and is only needed on a few boards. Reverting this reduces time to set up driver model by about 30ms.
