2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2023-10-13dfu: mtd: mark bad the MTD block on erase errorPatrick Delaunay
In the MTD DFU backend, it is needed to mark the NAND block bad when the erase failed with the -EIO error, as it is done in UBI and JFFS2 code. This operation is not done in the MTD framework, but the bad block tag (in BBM or in BBT) is required to avoid to write data on this block in the next DFU_OP_WRITE loop in mtd_block_op(): the code skip the bad blocks, tested by mtd_block_isbad(). Without this patch, when the NAND block become bad on DFU write operation - low probability on new NAND - the DFU write operation will always failed because the failing block is never marked bad. This patch also adds a test to avoid to request an erase operation on a block already marked bad; this test is not performed in MTD framework in mtd_erase().

2023-10-13dfu: mtd: fix the trace when limit is reachedPatrick Delaunay
The offset variable = 'off' used in the error trace when limit is reach on erase operation is incorect as 'erase_op.addr' is used in the loop. This patch corrects the copy paste issue between the erase loop and the write loop. This patch also adds the 'remaining' information to allow to debug of limit issues.

2023-06-16dfu: mtd: remove direct call of mtdparts_init functionPatrick Delaunay
With MTD support in driver model, the direct call of mtdparts_init should be avoided and replaced by mtd_probe_devices. With the modificaton when MTDIDS/MTDPARTS are empty the OF fallback with partition describe in device tree is correctly performed, introduced by commit dc339bf784f0 ("mtd: add support for parsing partitions defined in OF"). With this patch the dependency with CONFIG_CMD_MTDPARTS is removed. Signed-off-by: Patrick Delaunay <[email protected]> Reviewed-by: Patrice Chotard <[email protected]>
2022-02-11DFU: Check the number of arguments and argument string strictlyMasami Hiramatsu
When parsing the dfu_alt_info, check the number of arguments and argument string strictly. If there is any garbage data (which is not able to be parsed correctly) in dfu_alt_info, that means something wrong and user may make a typo or mis- understanding about the syntax. Since the dfu_alt_info is used for updating the firmware, this mistake may lead to brick the hardware. Thus it should be checked strictly for making sure there is no mistake.

2022-02-11DFU: Accept redundant spaces and tabs in dfu_alt_infoMasami Hiramatsu
If dfu_alt_info has repeated spaces or tab (for indentation or readability), the dfu fails to parse it. For example, if dfu_alt_info="mtd nor1=image raw 100000 200000" (double spaces after "raw"), the image entity start address is '0' and the size '0x100000'. This is because the repeated space is not skipped. Use space and tab as a separater and apply skip_spaces() to skip redundant spaces and tabs. Signed-off-by: Masami Hiramatsu <[email protected]>
2022-01-28dfu: mtd: skip empty pages when writing page for UBI partitionPatrick Delaunay
Align the DFU MTD backend for the UBI partitions with the mtd command write behavior when the option .dontskipff is not used: don't write the empty pages (full of 0xFF); it is not required for UBI, see [1] for details. This patch avoids the "free space fixup" procedure in the kernel [2] and allows to program a UBIFS volume generated by mkfs.ubifs without the option -F, --space-fixup. The MTD DFU backend implements this behavior introduced on DFU NAND backend by the commit 13cb7cc9e8e4 ("dfu: Add option to skip empty pages when flashing UBI images to NAND") and also supported by the command nand by CONFIG_CMD_NAND_TRIMFFS and by commit c9494866df83 ("cmd_nand: add nand write.trimffs command").

2021-06-18dfu: dfu_mtd: set max_buf_size to erasesize also for NOR devicesPatrick Delaunay
For NOR devices the logical DFU buffer size is the sector_size, as it is done in dfu_sf.c or in spi/sf_mtd.c (sf_mtd_info.erasesize = flash->sector_size) For NAND the DFU size was already limited to erasesize as has_pages = true. So the mtd dfu backend can use this erasesize for all the MTD devices, NOR and NAND with dfu->max_buf_size = mtd->erasesize This difference was initially copied from MTD command, where data is fully available in RAM without size limitation. This patch avoids to have many sector write in dfu_mtd.c at the end of the DFU transfer and avoids issues with USB timeout or WATCHDOG.

At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres.
