cmd: mmc: fix help and parameter verification with MMC_SPEED_MODE_SET not set

2026-06-09T15:55:56Z

Currently help and parameter scanning does not check whether the feature is enabled or not. This leads to wrong expectations based on help output and no clear sign why the mmc dev and mmc rescan do not enforce the supplied mode.

cmd: mmc: Drop trailing space in Name: before newline

2026-02-25T07:07:54Z

The Name: line of 'mmc info' command prints a trailing space before newline. This is not useful and shows up as trailing space e.g. when the output is checked into documentation. Remove the trailing space. Signed-off-by: Marek Vasut Reviewed-by: Tom Rini Reviewed-by: Mattijs Korpershoek Signed-off-by: Peng Fan

cmd: mmc: Check whether arguments are valid numbers in dev subcommand

2026-02-03T14:11:45Z

Currently when any of speed_mode, part, or dev fails to be parse as a number, no error is reported. In this case __init_mmc_device() is called with weird arguments, probably zeroes if there's no digit prefixing the argument, which is especially confusing when the invocation occasionally succeeds. Let's check whether arguments are valid numbers without trailing characters. This is quite helpful for speed_mode: it requires an index instead of a mode name, one may easily pass in a string, which will be parsed as zero (MMC_LEGACY), without carefully reading the documentation, then finds the MMC device is under an unexpected mode.

global: Avoid indirect inclusion of from

2025-05-29T14:29:16Z

The include file does not need anything from . Furthermore, include/env.h itself includes other headers which can lead to longer indirect inclusion paths. To prepare to remove from fix all of the places which had relied on this indirect inclusion to instead include directly.

Merge patch series "Fix various bugs"

2024-09-18T19:07:19Z

Simon Glass says: This series includes the patches needed to make make the EFI 'boot' test work. That test has now been split off into a separate series along with the EFI patches. This series fixes these problems: - sandbox memory-mapping conflict with PCI - the fix for that causes the mbr test to crash as it sets up pointers instead of addresses for its 'mmc' commands - the mmc and read commands which cast addresses to pointers - a tricky bug to do with USB keyboard and stdio - a few other minor things

mmc: Use map_sysmem() with buffers in the mmc command

2024-09-18T19:01:00Z

The current implementation casts an address to a pointer. Make it more sandbox-friendly by using map_sysmem(). Rename the variable to 'ptr' since it is a pointer, not an address. Signed-off-by: Simon Glass

cmd: mmc: Allow using partition name in mmc erase command

2024-09-16T22:45:55Z

The mmc erase command currently requires blk# and cnt parameters which can be obtained using the part start and part size commands if the entire partition needs to be erased. Simplify the use of the mmc erase command by allowing the partition name to be specified directly. Signed-off-by: Tomas Paukrt Reviewed-by: Quentin Schulz
