2025-04-16xilinx: versal: add firmware access to PMC multi Boot mode registerPrasad Kummari
Added extended support for retrieving the PMC muti boot mode register via the firmware interface, which is preferred when U-Boot runs in EL2 and cannot directly access PMC registers via raw reads. Ideally, all secure registers should be accessed via xilinx_pm_request(). Introduced the secure zynqmp_pm_get_pmc_multi_boot_reg() call, which uses xilinx_pm_request() to read the PMC multi boot mode register. BootROM increments the MultiBoot register (PMC_MULTI_BOOT) read address offset by 32 KB and retries. For SD and eMMC boot modes, it can search up to 8191 FAT files for the identification string. A 13-bit mask (0x1FFF) is applied to PMC_MULTI_BOOT_MASK to obtain the correct values in BootROM.

2025-04-16arm64: zynqmp: versal: Consistently use enum tcm_modeMarek Vasut
Turn anonymous enum TCM_LOCK/TCM_SPLIT into enum tcm_mode {}, set TCM_LOCK as 0 and TCM_SPLIT as 1 to match LOCK and SPLIT macros in mach-zynqmp/mp.c, and unify all the functions and their parameters on this one single enum tcm_mode {} instead of a mix of bool and u8. No functional change intended.

2023-10-09arm64: versal: Add SelectMAP boot mode identificationPolak, Leszek
The SelectMAP configuration interface provides an 8-bit, 16-bit or 32-bit bidirectional data bus interface to the Versal FPGA configuration logic that can be used for both configuration and readback. A connected microcontoller to the SelectMAP interface can load boot image with bitstream, TF-A (ARM Trusted Firmware) and U-Boot. This commit adds the missing identification of the SelectMAP mode.

On versal platform, enable apb linear mode for apb read and write execute operations amd disable it when using dma reads. This is done by xilinx_pm_request() secure calls when CONFIG_ZYNQMP_FIRMWARE is enabled, else we use direct raw reads and writes in case of mini U-Boot.

2022-06-29spi: cadence-qspi: reset qspi flash for versal platformT Karthik Reddy
When flash operated at non default mode like DDR, flash need to be reset to operate in SDR mode to read flash ids by spi-nor framework. Reset the flash to the default state before using the flash. This reset is handled by a gpio driver, in case of mini U-Boot as gpio driver is disabled, we do raw read and write access by the registers. Versal platform utilizes spi calibration for read delay programming, so incase by default read delay property is set in DT. We make sure not to use read delay from DT by overwriting read_delay with -1.
