2018-06-19bootm: Handle kernel_noload on arm64Marek Vasut
The ARM64 has 2 MiB alignment requirement for the kernel. When using fitImage, this requirement may by violated, the kernel will thus be executed from unaligned address and fail to boot. Do what booti does and run booti_setup() for kernel_noload images on arm64 to obtain a suitable aligned address to which the image shall be relocated.

2018-05-08bootm.c: Correct the flush_len used in bootm_load_os()Tom Rini
In do_bootm_states when doing BOOTM_STATE_LOADOS we use load_end uninitialized and Coverity notes this now. This however leads down another interesting path. We pass this pointer to bootm_load_os and that in turn uses this uninitialized value immediately to calculate the flush length, and is wrong. We do not know what load_end will be until after bootm_decomp_image is called, so we must only set flush_len after that. All of this also makes it clear that the only reason we pass a pointer for load_end to bootm_load_os is so that we can call lmb_reserve on success. Rather than initialize load_end to 0 in do_bootm_states we can just call lmb_reserve ourself.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-17bootm: Align cache flush begin addressBryan O'Donoghue
commit b4d956f6bc0f ("bootm: Align cache flush end address correctly") aligns the end address of the cache flush operation to a cache-line size to ensure lower-layers in the code accept the range provided and flush. A similar action should be taken for the begin address of a cache flush operation. The load address may not be aligned to a cache-line boundary, so ensure the passed address is aligned.

2016-07-14bootm: fixup silent Linux out of BOOTM_STATE_LOADOS stateHector Palacios
The function fixup_silent_linux() is called in status BOOTM_STATE_LOADOS to silence Linux if variable 'silent' is set. Currently only the 'bootm' command state machine contains BOOTM_STATE_LOADOS, but others like 'booti' or 'bootz' commands do not. This means silent Linux does not work with these commands. This patch moves the fixup_silent_linux() call out of the BOOTM_STATE_LOADOS state and into BOOTM_STATE_OS_PREP, to silence Linux independently of the used command (booti, bootm or bootz).

2016-02-26image: Correct the OS location code to work on sandboxSimon Glass
A recent change broke the 'bootm' command on sandbox. The root cause is using a pointer as an address. Conversion from pointer to address needs to use map_to_sysmem() so that sandbox can do the right thing. The problem was pre-existing but uncovered by a recent commit. Fix this. Also move fit_get_end() to the C file to avoid needing to include mapmem.h (and thus asm/io.h) everywhere.

2016-01-25bootm: fix size arg of flush_cache() in bootm_load_os().Purna Chandra Mandal
Variable _load_end_ points to end address of uncompressed buffer (*not* uncomress_buffer_end / sizeof(ulong)), so multipling uncompressed size with sizeof(ulong) is grossly incorrect in flush_cache(). It might lead to access of address beyond valid memory range and hang the CPU. Tested on MIPS architecture by using compressed(gzip, lzma) and uncompressed uImage.

2015-10-11Add support for LZ4 decompression algorithmJulius Werner
This patch adds support for LZ4-compressed FIT image contents. This algorithm has a slightly worse compression ration than LZO while being nearly twice as fast to decompress. When loading images from a fast storage medium this usually results in a boot time win. Sandbox-tested only since I don't have a U-Boot development system set up right now. The code was imported unchanged from coreboot where it's proven to work, though. I'm mostly interested in getting this recognized by mkImage for use in a downstream project.
