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

mmc: Use proper IS_ENABLED macro to check block support

2019-01-16T12:56:43Z

Use CONFIG_IS_ENABLED(BLK) instead of CONFIG_BLK, in order to fix the following build issues when CONFIG_SPL_MMC_WRITE is selected: drivers/mmc/mmc_write.c:69:7: error: conflicting types for 'mmc_berase' ulong mmc_berase(struct udevice *dev, lbaint_t start, lbaint_t blkcnt) ^~~~~~~~~~ In file included from drivers/mmc/mmc_write.c:15:0: drivers/mmc/mmc_private.h:39:7: note: previous declaration of 'mmc_berase' was here ulong mmc_berase(struct blk_desc *block_dev, lbaint_t start, lbaint_t blkcnt); ^~~~~~~~~~ drivers/mmc/mmc_write.c:187:7: error: conflicting types for 'mmc_bwrite' ulong mmc_bwrite(struct udevice *dev, lbaint_t start, lbaint_t blkcnt, ^~~~~~~~~~ In file included from drivers/mmc/mmc_write.c:15:0: drivers/mmc/mmc_private.h:37:7: note: previous declaration of 'mmc_bwrite' was here ulong mmc_bwrite(struct blk_desc *block_dev, lbaint_t start, lbaint_t blkcnt, ^~~~~~~~~~ Signed-off-by: Ezequiel Garcia Reviewed-by: Daniel Schwierzeck

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

dm: mmc: Support erase

2016-10-10T03:36:27Z

At present erase is not suported with CONFIG_DM_OPS. Add it so that MMC devices can be erased. Signed-off-by: Simon Glass

mmc: sd: optimize erase

2016-09-19T21:46:01Z

To SD, there is no erase group, then the value erase_grp_size will be default 1. When erasing SD blocks, the blocks will be erased one by one, which is time consuming. We use AU_SIZE as a group to speed up the erasing. Erasing 4MB with a SD2.0 Card with AU_SIZE 4MB. `time mmc erase 0x100000 0x2000` time: 44.856 seconds (before optimization) time: 0.335 seconds (after optimization) Signed-off-by: Peng Fan Cc: Jaehoon Chung Cc: Simon Glass Cc: Bin Meng Cc: Stefan Wahren Cc: Clemens Gruber Cc: Kever Yang Cc: Eric Nelson Cc: Stephen Warren

dm: mmc: Add support for driver-model block devices

2016-05-17T15:54:43Z

Add support for enabling CONFIG_BLK with MMC. This involves changing a few functions to use struct udevice and adding a MMC block device driver. Signed-off-by: Simon Glass

dm: mmc: Move the device list into a separate file

2016-05-17T15:54:43Z

At present the MMC subsystem maintains its own list of MMC devices. This cannot work with driver model, which needs to maintain this itself. Move the list code into a separate 'legacy' file. The core MMC code remains, and will be shared with the driver-model implementation. Signed-off-by: Simon Glass
