| * vsprintf: implement %pJP for printing JSONPathsAhmad Fatoum2023-01-101-0/+44
| | | | | | | | | | | | | | | | | | | | We use an array of strings to represnt a JSONPath. Add a new %pJP format specifier that can be used to print them. This is useful for error messages when the lookup fails.

* KASan: fix handling of devices with MMIO above SDRAM memory regionAhmad Fatoum2022-12-131-0/+5
| | | | | | | | | | | | | | check_memory_region_inline will discard KASan reports before start of RAM as false positives. This is sufficient for i.MX SoCs where the RAM starts after all device MMIO regions. On the AT91, the EBI memory controller's memory region follows the SDRAM memory region. This results in a KASan warning the first time NAND is accessed. Record the end of the shadowed SDRAM area to fix this.

Ideally the whitespaces should only be escaped when we are outside of double or single quotes, but our completion currently doesn't trigger at all when invokes inside quotes, so we can ignore this case for now.

* | Revert "lib: zstd: sync with Linux"Sascha Hauer2022-09-3037-9322/+6786
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was part of a larger series that made it possible to use other compression algos than LZO for device tree and to use zstd more widely for barebox and kernel compression. The latter zstd-related parts needed rework and were not merged, but the zstd update was applied. It broken in turn the UBIFS zstd support. As we get nothing out of the update without the not applied commits that need rework anyway, revert this commit. This reverts commit b4a9782d4f56333e897dccc35c2c27e2605f6b93.

| * FIT: add first support for compressed imagesAhmad Fatoum2022-08-111-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FIT image contents are often compressed, but we got by so far, because a compressed initramfs is usually meant to be decompressed by the kernel (and so has compression = "none") and arm32 kernels had their own decompresser embedded. On ARM64, bootloader is responsible for uncompressing kernel, so we should properly process the compression property we so far ignored. The decompression isn't as efficient as one would hope for, because the FIT format only describes length of the compressed data. We thus have two options: - define an output size up-front, e.g. by guessing the uncompressed buffer size for decompression or hardcoding it (e.g. U-Boot's CONFIG_SYS_BOOTM_LEN). - Uncompress to a file descriptor We choose the second one to play it safe, but it comes with worse performance because of extra memory copies. Intention is to go with first option for the kernel image: We know how much size we can spare for the kernel image and can have bootm_load_os uncompress there directly without intermittent memory copies. This would involve slight change to the barebox decompresser API to align it with the kernel's, which allows to have it accept and observe an output buffer size. So far, we had the kernel PREBOOT API, which lacks such a parameter, but that's an optimization for another day.

In barebox only care about decoding, the qoi image format might be an intresting alternative to both bmp and png, some kind of midle ground. The project home page can be found at https://qoiformat.org, there is a reference implementation, for both encoder and decoder, in a single header file (qoi.h) hosted at https://github.com/phoboslab/qoi. There is no plan for future version, this is a frozen format. In case the reference implementation should be updated, the qoi.h file must be copied to the lib/gui/qoi.h without requiring modifications.

* | getopt: Add support for '+' in optstringSascha Hauer2022-01-051-3/+14
| | | | | | | | | | | | | | Stop option parsing at nonoptions when the first character of optstring is '+'. This is analog to getopt(3). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | parseopt: drop unused, duplicate, parseopt_u16Ahmad Fatoum2022-01-051-31/+0
|/ | | | | | | | | | | We always have sizeof(unsigned short) == sizeof(uint16_t), so parseopt_u16() is exactly equivalent to parseopt_hu(). The former is unused anyway, so just drop it.

* common: add new PRINTF_FULL optionAhmad Fatoum2021-12-141-0/+3
