[PATCH v2 1/2] mmc: sdhci: continue normal tuning if unsupported by platform tuning

Some SDHCI-compat controllers support not only SD, but also eMMC, but they use different commands for tuning: CMD19 for SD, CMD21 for eMMC. Due to the difference of the underlying mechanism, some controllers (at least, the Cadence IP is the case) provide their own registers for the eMMC tuning.

[PATCH v8 09/10] ima: define a canonical binary_runtime_measurements list format

[PATCH v8 06/10] ima: on soft reboot, save the measurement list
