arm64: versal-net: Move bootmode decoding out of board code

2026-07-08T06:55:51Z

versal_net_get_bootmode() open-coded the IS_ENABLED(CONFIG_ZYNQMP_FIRMWARE) selection between the firmware call zynqmp_pm_get_bootmode_reg() and a direct readl() in board code. Like the Versal change, move the whole function behind an overridable hook so generic board code stays free of firmware specifics and is ready for SCMI. The weak versal_net_get_bootmode() in arch/arm/mach-versal-net does the plain MMIO read via versal_net_bootmode_reg() and decodes it (used at EL3 and without firmware). When CONFIG_ZYNQMP_FIRMWARE is enabled, firmware-zynqmp.c provides a strong definition that reads the register through the firmware call, falling back to the direct read at EL3 where the SMC path to firmware is unavailable. This preserves the existing firmware-based bootmode behaviour while removing the firmware interface from board code; the now unused zynqmp_firmware.h include is dropped.

arm64: versal-net: Move board_early_init_r clock setup to mach code

2026-07-08T06:55:51Z

board_early_init_r() programmed the IOU switch clock and the system timestamp counter directly with readl()/writel() in board code. This is SoC register setup rather than board policy, and the same block is duplicated across the Xilinx SoCs. Move it into versal_net_timer_setup() in arch/arm/mach-versal-net so the board hook only keeps the EL3 guard and calls the helper.

arm64: versal: Add SelectMAP boot mode identification

2023-10-09T11:03:23Z

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.

xilinx: Consolidate zynqmp_mmio_read/write in zynqmp_firmware.h

zynqmp_mmio_read/write() are firmware provided hooks that's why use only zynqmp_firmware.h for function declaration. Signed-off-by: Michal Simek Link: https://lore.kernel.org/r/e7489556f9e447c737a578c169d7e1e43586a273.1687524706.git.michal.simek@amd.com

cadence_qspi: Enable flash reset for Versal NET platform

2023-07-21T07:00:38Z

Enable flash reset functionality for Versal NET platform. In cadence_qspi.c there is weak function defined for reset, hence remove the check for config, so that it will work for Versal and Versal NET platforms. Add register defines in Versal NET hardware.h for mini U-Boot flash reset. Add read_delay initialization for Versal NET also.

arm64: versal-net: Add support for SPP production version

2023-06-12T11:24:31Z

Production version restarting platform version field from 0 that's why add new calculation to be able to use different DT for these platforms. Requested DT names for production silicons for IPP/SPP and EMU platform are versal-net-ipp-rev2.0.dts and versal-net-emu-rev2.0.dts. If platform version increase numbers revision can be even higher. As of today platform version is 2 that's why expected is rev2.2.

Read boodmode register using versal_net_get_bootmode() in board_late_init and prepare corresponding distro boot command sequence based on it. versal_net_get_bootmode() will be changed to use smc calls later, but for now directly reads the register.

2023-01-16T14:34:37Z

Add support for starting timer by setting up time stamp generator registers. This is done only for EL3 i.e. mini U-Boot case. For other cases, it will be done TF-A. Add COUNTER_FREQUENCY and IOU_SWITCH_DIVISOR0 to Kconfig so that they can be tuned as required.
