mmc: erase: Use TRIM erase when available

2023-04-10T03:17:24Z

The default erase command applies on erase group unit, and simply round down to erase group size. When the start block is not aligned to erase group size (e.g. erasing partition) it causes unwanted erasing of the previous blocks, part of the same erase group (e.g. owned by other logical partition, or by the partition table itself). To prevent this issue, a simple solution is to use TRIM as argument of the Erase command, which is usually supported with eMMC > 4.0, and allow to apply erase operation to write blocks instead of erase group Signed-off-by: Loic Poulain Reviewed-by: Simon Glass

blk: Switch over to using uclass IDs

2022-09-16T15:05:16Z

We currently have an if_type (interface type) and a uclass id. These are closely related and we don't need to have both. Drop the if_type values and use the uclass ones instead. Maintain the existing, subtle, one-way conversion between UCLASS_USB and UCLASS_MASS_STORAGE for now, and add a comment. Signed-off-by: Simon Glass

mmc: fix error message for unaligned erase request

2022-06-15T06:34:18Z

Fix the end address in the message for unaligned erase request in mmc_berase() when start + blkcnt is aligned to erase_grp_size. for example: - start = 0x2000 - 26 - count = 26 - erase_grp_size = 0x400 Caution! Your devices Erase group is 0x400 The erase range would be change to 0x2000~0x27ff But no issue when the end address is not aligned, for example - start = 0x2000 - 2 * 26 - count = 26 - erase_grp_size = 0x400 Caution! Your devices Erase group is 0x400 The erase range would be change to 0x2000~0x23ff Signed-off-by: Patrick Delaunay Reviewed-by: Jaehoon Chung Reviewed-by: Patrice Chotard

dm: treewide: Rename 'platdata' variables to just 'plat'

2020-12-13T23:51:08Z

We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass

mmc: Rename timeout parameters for clarification

2019-09-05T07:27:31Z

It's quite hard to figure out time units for various function that have timeout parameters. This leads to possible errors when one forgets to convert ms to us, for example. Let's rename those parameters correspondingly to 'timeout_us' and 'timeout_ms' to prevent such issues further. While at it, add time units info as comments to struct mmc fields. This commit doesn't change the behavior, only renames parameters names. Buildman should report no changes at all. Signed-off-by: Sam Protsenko Reviewed-by: Peng Fan Reviewed-by: Igor Opaniuk

mmc: add mmc_poll_for_busy() and change the purpose of mmc_send_status()

2019-07-15T02:16:49Z

mmc_send_status() is currently used to poll the card until it is ready, not actually returning the status of the card. Make it return the status and add another function to poll the card. Also remove the 'extern' declaration in the mmc-private.h header to comply with the coding standard. Signed-off-by: Jean-Jacques Hiblot

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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
