2024-01-15cmd: mtd: avoid unintentional integer overflowHeinrich Schuchardt
mtd dump beyond 4 GiB will show incorrect results. Multiplying two u32 will yield a u32. Add a missing cast.

2023-10-16cmd: Convert existing long help messages to the new macroTom Rini
- Generally we just drop the #ifdef CONFIG_SYS_LONGHELP and endif lines and use U_BOOT_LONGHELP to declare the same variable name as before - In a few places, either rename the variable to follow convention or introduce the variable as it was being done inline before.

2022-12-10cmd: mtd: check if a block has to be skipped or erasedDario Binacchi
As reported by patch [1], the `mtd erase' command should not erase bad blocks. To force bad block erasing you have to use the `mtd erase.dontskipbad' command. This patch tries to fix the same issue without modifying code taken from the linux kernel, in order to make further upgrades easier.

2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-02-05dm: core: Require users of devres to include the headerSimon Glass
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.

2020-01-24cmd: mtd: solve bad block support in erase commandPatrick Delaunay
This patch modify the loop in mtd erase command to erase one by one the blocks in the requested area. It solves issue on "mtd erase" command on nand with existing bad block, the command is interrupted on the first bad block with the trace: "Skipping bad block at 0xffffffffffffffff" In MTD driver (nand/raw), when a bad block is present on the MTD device, the erase_op.fail_addr is not updated and we have the initial value MTD_FAIL_ADDR_UNKNOWN = (ULL)-1. This case seems normal in nand_base.c:nand_erase_nand(), we have the 2 exit cases during the loop: 1/ we have a bad block (nand_block_checkbad) instr->state = MTD_ERASE_FAILED loop interrupted (goto erase_exit) 2/ if block erase failed (status & NAND_STATUS_FAIL) instr->state = MTD_ERASE_FAILED; instr->fail_addr = ((loff_t)page << chip->page_shift); loop interrupted (goto erase_exit) So erase_op.fail_addr can't be used if bad blocks were present in the erased area; we need to use mtd_erase only one block to detect and skip these existing bad blocks (as it is done in nand_util.c).

cmd/mtd.c:447:13: warning: ‘mtd_help_text’ defined but not used [-Wunused-variable] static char mtd_help_text[] = ^~~~~~~~~~~~~ When SYS_LONGHELP is not defined. After looking at how other commands work, we should surround the whole help text (even its declaration) with an #ifdef CONFIG_SYS_LONGHELP, since it's compiled out when calling _CMD_HELP[1] on the help text variable argument to U_BOOT_CMD.

2018-10-02cmd: mtd: add 'mtd' commandMiquel Raynal
There should not be a 'nand' command, a 'sf' command and certainly not a new 'spi-nand' command. Write a 'mtd' command instead to manage all MTD devices/partitions at once. This should be the preferred way to access any MTD device.
