Could you run this serie on the r8a779f0_spider, j721s2_evm_a72, j721e_evm_a72, j7200_evm_a72, amd_versal2_virt and qemu-riscv and check for possible regressions ? It seems the only user of UFS_PCI is qemu-riscv, is there other users ?

Good timing. We are close to send some updates to UFS which we require to get DWC version to work inside U-Boot. How far are that core changes from Linux? I see 9/13 is sync with Linux but when this is done you should also say which Linux version was used for sync. I see that there are definitely some kernel-doc issues Also s/U-boot/U-Boot/g Venkatesh: Can you please look at this patch series and validate it on our platform? Also make sense to send our changes to make sure that they won't break others. Thanks, Michal

I see 9/13 is sync with Linux but when this is done you should also say which Linux version was used for sync. I think we are still quite far from Linux, we just took the basic required bits and pieces to at least make the Qcom UFS controller driver build work, but Linux driver is overly complicated with power management code we do not really need in U-Boot, so it's quite hard to sync honestly. But the plan is to align as much as possible once we get the basic Qcom UFS mainline. > > I see that there are definitely some kernel-doc issues > > Also s/U-boot/U-Boot/g Ack, will check > > Venkatesh: Can you please look at this patch series and validate it on our platform?

That's understandable. But even when you say sync with Linux for some headers, etc it is good to say that it is sync with 6.11 for example. Thanks, Michal

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.
