2023-10-31fastboot: fix CRC32 chunk size checkingWojciech Nizinski
genimage create android-sparse file with CRC32 chunk at end. When U-Boot's fastboot receives this chunk it returns error message: `Fail Bogus chunk size for chunk type Dont Care` According to reference implementation of Android's sparse file format: <https://android.googlesource.com/platform/system/core/+/refs/heads/main/ libsparse/output_file.cpp#513> the chunk_header.total_sz is CHUNK_HEADER_LEN + 4 (CRC32 size).

2023-07-25lib: sparse: allocate FASTBOOT_MAX_BLK_WRITE instead of small numberMattijs Korpershoek
Commit 62649165cb02 ("lib: sparse: Make CHUNK_TYPE_RAW buffer aligned") fixed cache alignment for systems with a D-CACHE. However it introduced some performance regressions [1] on system flashing huge images, such as Android. On AM62x SK EVM, we also observe such performance penalty: Sending sparse 'super' 1/2 (768793 KB) OKAY [ 23.954s] Writing 'super' OKAY [ 75.926s] Sending sparse 'super' 2/2 (629819 KB) OKAY [ 19.641s] Writing 'super' OKAY [ 62.849s] Finished. Total time: 182.474s The reason for this is that we use an arbitrary small buffer (info->blksz * 100) for transferring. Fix it by using a bigger buffer (info->blksz * FASTBOOT_MAX_BLK_WRITE) as suggested in the original's patch review [2]. With this patch, performance impact is mitigated: Sending sparse 'super' 1/2 (768793 KB) OKAY [ 23.912s] Writing 'super' OKAY [ 15.780s] Sending sparse 'super' 2/2 (629819 KB) OKAY [ 19.581s] Writing 'super' OKAY [ 17.192s] Finished.

CHUNK_TYPE_RAW buffer is not aligned, and flash sparse images by fastboot will report "Misaligned operation" if DCACHE is enabled. Flashing Sparse Image CACHE: Misaligned operation at range [84000028, 84001028] CACHE: Misaligned operation at range [84001034, 84002034] CACHE: Misaligned operation at range [8401104c, 8401304c] Fix it Signed-off-by: qianfan Zhao <qianfanguijin@163.com> Reviewed-by: Sean Anderson <sean.anderson@seco.com>
2021-06-01fastboot: Fix overflow when calculating chunk sizeSean Anderson
If a chunk was larger than 4GiB, then chunk_data_sz would overflow and blkcnt would not be calculated correctly. Upgrade it to a u64 and cast its multiplicands as well. Also fix bytes_written while we're at it. Signed-off-by: Sean Anderson <sean.anderson@seco.com> Reviewed-by: Heiko Schocher <hs@denx.de>

2020-05-18common: Drop net.h from common headerSimon Glass
Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-05-30mmc: Separate "mmc swrite" from fastbootAlex Kiernan
Introduce CONFIG_IMAGE_SPARSE and CONFIG_CMD_MMC_SWRITE so the "mmc swrite" command is separated from the fastboot code. Move image-sparse from common to lib so it's clear it's library code. Rename CONFIG_FASTBOOT_FLASH_FILLBUF_SIZE to CONFIG_IMAGE_SPARSE_FILLBUF_SIZE and migrate it to Kconfig.
