[PATCH 0/4] xilinx: Add SoC Xilinx driver for zynqmp & versal

[Michal Simek]

Hi,

This patch series adds support for SoC Xilinx driver to get SoC family
and revision. Print SoC info using print_cpuinfo() at booting stage.

Thanks,
Michal

[PATCH 1/4] soc: xilinx: zynqmp: Add soc_xilinx_zynqmp driver

[Michal Simek]

From: T Karthik Reddy <t.karthik.reddy@xilinx.com>

soc_xilinx_zynqmp driver allows identification of family & revision
of zynqmp SoC. This driver is selected by CONFIG_SOC_XILINX_ZYNQMP.
Add this config to xilinx_zynqmp_virt_defconfig file.
Probe this driver using platdata U_BOOT_DEVICE structure which is
specified in mach-zynqmp/cpu.c.

[PATCH 2/4] soc: xilinx: versal: Add soc_xilinx_versal driver

[Michal Simek]

From: T Karthik Reddy <t.karthik.reddy@xilinx.com>

soc_xilinx_versal driver allows identification of family & revision
of versal SoC. This driver is selected by CONFIG_SOC_XILINX_VERSAL.
Probe this driver using platdata U_BOOT_DEVICE structure which is
defined at mach-versal/cpu.c.
Add this config to xilinx_versal_virt_defconfig &
xilinx_versal_mini_ospi_defconfig file to select this driver.
