This serie regroups all the fixes and base enhancements required to support the Qualcomm UFS controllers in U-Boot.
This syncs headers & defines from Linux, and includes 2 set of fixes that were sent separately: - ufs: core: remove link_startup_again logic - ufs: properly fix cache operations
Without those 2 sets, UFS cannot initialize on Qualcomm controlers since v5, and a numerous of Cache issues makes any UFS controller fail to initialize.
Since UFS core hasn't changed for a while, and since UFS is core technology for the Qualcomm SoCs, I volunteer maintaininig the UFS subsystem if Bhupesh & Neha Malcom Francis are ok with that.
It has been reported to show regressions on: - TI K3 platforms (j721s2, j721e, j7200, j784s4) [1] - AMD platform (amd_versal2_virt_defconfig) [2]
