This series adds UFS boot support in SPL for Qualcomm Snapdragon platforms, along with the necessary driver and infrastructure changes to support it.
Patch 1 renames SPL_UFS_SUPPORT to SPL_UFS for naming consistency. Patch 2 renames SPL_UFS_SUPPORT to SPL_UFS for defconfigs. Patch 3 adds a Kconfig choice for U-Boot location: sector or partition. Patch 4 refactors spl_ufs.c to add partition-based U-Boot loading. Patch 5 enables part_get_info_ptr() in SPL for UFS partition boot. Patch 6 adds UFS_MODE_RAW and UFS_MODE_FS defines to spl.h. Patch 7 adds SPL_UFS_QCOM to enable the Qualcomm UFS HC driver in SPL. Patch 8 adds SPL_PHY_QCOM_QMP_UFS to enable the QMP UFS PHY in SPL. Patch 9 adds SPL_CLK_STUB Kconfig for the stub clock driver in SPL. Patch 10 updates charset.o build rule to use SPL_UFS after the rename. Patch 11 adds SPL_QCOM_GENI Kconfig and $(PHASE_) support for GENI. Patch 12 adds SPL_PINCTRL_QCOM_* symbols and $(PHASE_) Makefile support for all Qualcomm pinctrl drivers. Patch 13 adds SPL_MSM_SERIAL and SPL_MSM_GENI_SERIAL Kconfig and $(PHASE_) support for Qualcomm serial drivers. Patch 14 updates Qualcomm PMIC and SPMI Makefiles to use $(PHASE_).
