Add retry tuning up to 10 times if we fail to find a failing region or no passing itapdly. This is necessary since some eMMC has been observed to never find a failing itapdly on the first couple of tuning iterations, but eventually does. Keep count of current tuning iteration using tuning_loop. It has been observed that the tuning algorithm does not need to loop more than 10 times before finding a failing itapdly. Signed-off-by:

Until this patch was rpmb_dev_register() always freeing rdev in the error path. However, past device_register() it must not do that since the memory is now managed by the device even if it failed to register properly. So fix this by doing a put_device() before returning the error code. Fixes the smatch warning: drivers/misc/rpmb-core.c:204 rpmb_dev_register() warn: freeing device managed memory (leak): 'rdev' Fixes: 1e9046e3 ("rpmb: add Replay Protected Memory Block (RPMB) subsystem") Reported-by:

This means that CONFIG_OPTEE automatically becomes compiled as a module if CONFIG_RPMB is compiled as a module.

simple_strtoul() is obsolete and lacks proper error handling, making it unsafe for converting strings to unsigned long values. Replace it with kstrtoul(), which provides robust error checking and better safety. This change improves the reliability of the string-to-integer conversion and aligns with current kernel coding standards. Error handling is added to catch conversion failures, returning -EINVAL when input is invalid. Issue reported by checkpatch: - WARNING: simple_strtoul is obsolete, use kstrtoul instead Signed-off-by:

Commit 616f8766 ("mmc: pass queue_limits to blk_mq_alloc_disk") [1] revealed the long living issue in dw_mmc.c driver, existing since the time when it was first introduced in commit f95f3850 ("mmc: dw_mmc: Add Synopsys DesignWare mmc host driver."), also making kernel boot broken on platforms using dw_mmc driver with 16K or 64K pages enabled, with this message in dmesg: mmcblk: probe of mmc0:0001 failed with error -22 That's happening because mmc_blk_probe() fails when it calls blk_validate_limits() consequently, which returns the error due to failed max_segment_size check in this code: /* * The maximum segment size has an odd historic 64k default that * drivers probably should override. Just like the I/O size we * require drivers to at least handle a full page per segment. */ ... if (WARN_ON_ONCE(lim->max_segment_size < PAGE_SIZE)) return -EINVAL; In case when IDMAC (Internal DMA Controller) is used, dw_mmc.c always sets .max_seg_size to 4 KiB: mmc->max_seg_size = 0x1000; The comment in the code above explains why it's incorrect. Arnd suggested setting .max_seg_size to .max_req_size to fix it, which is also what some other drivers are doing: $ grep -rl 'max_seg_size.*=.*max_req_size' drivers/mmc/host/ | \ wc -l 18 This change is not only fixing the boot with 16K/64K pages, but also leads to a better MMC performance. The linear write performance was tested on E850-96 board (eMMC only), before commit [1] (where it's possible to boot with 16K/64K pages without this fix, to be able to do a comparison). It was tested with this command: # dd if=/dev/zero of=somefile bs=1M count=500 oflag=sync Test results are as follows: - 4K pages, .max_seg_size = 4 KiB: 94.2 MB/s - 4K pages, .max_seg_size = .max_req_size = 512 KiB: 96.9 MB/s - 16K pages, .max_seg_size = 4 KiB: 126 MB/s - 16K pages, .max_seg_size = .max_req_size = 2 MiB: 128 MB/s - 64K pages, .max_seg_size = 4 KiB: 138 MB/s - 64K pages, .max_seg_size = .max_req_size = 8 MiB: 138 MB/s Unfortunately, SD card controller is not enabled in E850-96 yet, so it wasn't possible for me to run the test on some cheap SD cards to check this patch's impact on those. But it's possible that this change might also reduce the writes count, thus improving SD/eMMC longevity. All credit for the analysis and the suggested solution goes to Arnd.

Adds support in the OP-TEE drivers (both SMC and FF-A ABIs) to probe and use an RPMB device via the RPMB subsystem instead of passing the RPMB frames via tee-supplicant in user space. A fallback mechanism is kept to route RPMB frames via tee-supplicant if the RPMB subsystem isn't available. The OP-TEE RPC ABI is extended to support iterating over all RPMB devices until one is found with the expected RPMB key already programmed. Signed-off-by:

A number of storage technologies support a specialised hardware partition designed to be resistant to replay attacks. The underlying HW protocols differ but the operations are common. The RPMB partition cannot be accessed via standard block layer, but by a set of specific RPMB commands. Such a partition provides authenticated and replay protected access, hence suitable as a secure storage. The initial aim of this patch is to provide a simple RPMB driver interface which can be accessed by the optee driver to facilitate early RPMB access to OP-TEE OS (secure OS) during the boot time. A TEE device driver can claim the RPMB interface, for example, via rpmb_interface_register() or rpmb_dev_find_device(). The RPMB driver provides a callback to route RPMB frames to the RPMB device accessible via rpmb_route_frames(). The detailed operation of implementing the access is left to the TEE device driver itself. Signed-off-by:

Applying MMC_QUIRK_BROKEN_SD_CACHE is broken, as the card's SD quirks are referenced in sd_parse_ext_reg_perf() prior to the quirks being initialized in mmc_blk_probe(). To fix this problem, let's split out an SD-specific list of quirks and apply in mmc_sd_init_card() instead. In this way, sd_read_ext_regs() to has the available information for not assigning the SD_EXT_PERF_CACHE as one of the (un)supported features, which in turn allows mmc_sd_init_card() to properly skip execution of sd_enable_cache().
