Currently, the QEMU-UFS emulation is implemented based on the JEDEC UFS
4.0 Specification and does not support the operation related to UFS Extended
Features which is defined with latest UFS Specifications.

This series modifies the UFS core implementation to align with the JEDEC
UFS 4.1 Specification[1], and adds a Write Booster UFS Extended Feature
supportability.

Tested: x86-64 KVM, upstream QEMU with Debian GNU/Linux 10
