This patch series optimize secure erase performance for certain Kingston
eMMC devices (IY2964 and IB2932) that take a fixed ~2 seconds per secure
erase operation regardless of size.

Currently, a 1GB secure erase requires ~300 operations (limited by max
discard size), taking ~10 minutes. With these changes, the same operation
completes in a single command, reducing time to just 2 seconds.

Luke Wang (2):
  block: decouple secure erase size limit from discard size limit
  mmc: add quirk to optimize certain Kingston eMMC secure erase/trim
    performance
