mmc: Introduce mmc_send_stop_transmission()

2023-07-18T00:17:16Z

If a tuning command times out, the card could still be processing it, which will cause problems for recovery. The eMMC specification section 6.6 Data transfer mode (cont’d) claims that CMD12 can be used to stop CMD21: " The relationship between the various data transfer modes is summarized (see Figure 27): - All data read commands can be aborted any time by the stop command (CMD12). The data transfer will terminate and the Device will return to the Transfer State. The read commands are: ... send tuning block (CMD21) .... " Add a function that does that. Based on Linux commit [1] and [2].

mmc: Check support for TRIM operations

2023-04-10T03:17:11Z

When secure/insecure TRIM operations are supported. When used as erase command argument it applies the erase operation to write blocks instead of erase groups. Signed-off-by: Loic Poulain Reviewed-by: Simon Glass Reviewed-by: Jaehoon Chung

cmd: mmc: Expand bkops handling

2023-01-31T13:02:27Z

Add more capable "bkops" command which allows enabling and disabling both manual and automatic bkops. The existing 'mmc bkops-enable' subcommand is poorly named to cover all the possibilities, hence the new-ish subcommand. Note that both commands are wrappers around the same common code.

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: Add support for wait_dat0 callback

2022-06-15T06:39:56Z

There is no wait_dat0 mmc ops, causing operations waiting for data line state change (e.g mmc_switch_voltage) to fallback to a 250ms active delay. mmc_ops still used when DM_MMC is not enabled, which is often the case for SPL. The result can be unexpectly long SPL boot time. This change adds support for wait_dat0() mmc operation. Signed-off-by: Loic Poulain Reviewed-by: Jaehoon Chung

bootstd: mmc: Add a bootdev driver
