mmc: core: Remove packed command leftovers

2023-12-07T13:08:44+00:00

Packed commands support was removed long time ago, but some bits got left behind. Remove them. Signed-off-by: Avri Altman Link: https://lore.kernel.org/r/20231030062226.1895692-1-avri.altman@wdc.com Signed-off-by: Ulf Hansson

mmc: core: Fix ambiguous TRIM and DISCARD arg

2022-11-18T09:39:22+00:00

Clean up the MMC_TRIM_ARGS define that became ambiguous with DISCARD introduction. While at it, let's fix one usage where MMC_TRIM_ARGS falsely included DISCARD too.

mmc: core: expose info about enhanced rpmb support

2020-05-28T09:21:03+00:00

Following eMMC JEDEC JESD84-B51 standard, an enhanced form of rpmb is supported. What this enhanced mode supports is in addition to be able to write one rpmb or two rpmb frames at a time, 32 frames can be written at a time. Expose this information present in ext csd field so that the user space application that wants to make use of this can do so.

mmc: core: Enable re-use of mmc_blk_in_tran_state()

2020-03-24T13:35:39+00:00

To allow subsequent changes to re-use the code from the static function mmc_blk_in_tran_state(), let's move it to a public header. While at it, let's also rename it to mmc_ready_for_data(), as to try to better describe its purpose.

mmc: core: Adjust and reuse the macro of R1_STATUS(x)

2018-07-16T09:21:45+00:00

R1_STATUS(x) now is only used by ioctl_rpmb_card_status_poll(), which checks all bits as possible. But according to the spec, bit 17 and bit 18 should be ignored, as well bit 14 which is reserved(must be set to 0) quoting from the spec and these rule apply to all places checking the device status. So change its checking from 0xFFFFE000 to 0xFFF9A000. As a bonus, we reuse it for mmc_do_erase() as well as mmc_switch_status_error(). (1) Currently mmc_switch_status_error() doesn't check bit 25, but it means device is locked but not unlocked by CMD42 prior to any operations which need check busy, which is also not allowed. (2) mmc_do_erase() also forgot to to check bit 15, WP_ERASE_SKIP. The spec says "Only partial address space was erased due to existing write protected blocks.", which obviously means we should fail this I/O. Otherwise, the partial erased data stored in nonvalatile flash violates the data integrity from the view of I/O owner, which probably confuse it when further used. So reusing R1_STATUS for them not only improve the readability but also slove real problems. Signed-off-by: Shawn Lin Signed-off-by: Ulf Hansson

mmc: Adding AUTO_BKOPS_EN bit set for Auto BKOPS support

Adding dedicated flag for AUTO_BKOPS in card->ext_csd structure. Read AUTO_BKOPS bit value from the device EXT_CSD and set to the card->ext_csd structure.

mmc: core: Remove unused struct _mmc_csd from public mmc.h header

The struct _mmc_csd isn't being used and has been lurking around for a while. Let's kill it. Signed-off-by: Ulf Hansson Reviewed-by: Linus Walleij Reviewed-by: Shawn Lin

mmc: core: Move erase/trim/discard defines from public core.h to mmc.h

As the public mmc.h header already contains similar defines for other mmc commands and arguments, let's move those for erase/trim/discard into here as well. Signed-off-by: Ulf Hansson Reviewed-by: Linus Walleij Reviewed-by: Shawn Lin

mmc: core: First step in cleaning up public mmc header files

2017-02-13T12:20:19+00:00

This is the first step in cleaning up the public mmc header files. In this change we makes sure each header file builds standalone, as that helps to resolve dependencies. While changing this, it also seems reasonable to stop including other headers from inside a header itself which it don't depend upon. Additionally, in some cases such dependencies are better resolved by forward declaring the needed struct. Signed-off-by: Ulf Hansson Reviewed-by: Shawn Lin
