Hi Lokesh, The following series adds the early-boot support of the revised R5FSS IP on J7200 SoCS from A72 U-Boot. The J7200 SoCs has two R5FSS clusters, one in MCU domain and another in MAIN domain. Patches are on top of the latest master + "Configure J721E Main R5FSS1 to Split-mode & env" series [1]. The current series enables the default variables only for the MAIN R5FSS cores. The config file used is common between J721E and J7200 SoCs, so is adjusted accordingly. The MCU R5FSS is shutdown at the end of R5 SPL, and can be booted by modifying env variables. Early-boot is supported only through the MMC rootfs just like on J721E SoCs. Following are the default modes and firmware image names supported with this series: 1. Modes MCU R5FSS0: LockStep mode MAIN R5FSS0: Split mode 2. Firmware images MCU R5FSS0 Core0 : j7200-mcu-r5f0_0-fw MCU R5FSS0 Core1 : j7200-mcu-r5f0_1-fw MAIN R5FSS0 Core0 : j7200-main-r5f0_0-fw MAIN R5FSS0 Core0 : j7200-main-r5f0_1-fw Following is the patch summary: - Patches #1 and #2 update the binding and the K3 R5F remoteproc driver for J7200 SoCs - Patch #3 sets up a separate MMU map for J7200 SoCs using the appropriate CONFIG_TARGET_<SOC>_A72_EVM symbols - Patches #4 and #5 add the dts nodes with LockStep for MCU R5FSS0 and Split-mode for MAIN R5FSS0 - Patch #6 leverages the CONFIG_TARGET_<SOC>_A72_EVM symbols to set the SoC-specific default remoteproc boot list - Patch #7 enables the R5F remoteproc driver and needed options for A72 U-Boot - Patch #8 enhances the bootcmd variable to include the booting of the rprocs based on couple of control variables regards Suman [1] https://patchwork.ozlabs.org/project/uboot/list/?series=196091 Suman Anna (8): dt-bindings: remoteproc: k3-r5f: Update bindings for J7200 SoCs remoteproc: k3-r5: Add support for J7200 R5Fs armv8: K3: j7200: Add custom MMU support arm: dts: k3-j7200-mcu: Add MCU domain R5F cluster node arm: dts: k3-j7200-main: Add MAIN domain R5F cluster nodes env: ti: j721e-evm: Update rproc_fw_binaries env variable for J7200 configs: j7200_evm_a72: Enable R5F remoteproc driver configs: j7200_evm_a72: Enhance bootcmd to start remoteprocs arch/arm/dts/k3-j7200-common-proc-board.dts | 7 ++ arch/arm/dts/k3-j7200-main.dtsi | 40 ++++++++ arch/arm/dts/k3-j7200-mcu-wakeup.dtsi | 40 ++++++++ arch/arm/mach-k3/arm64-mmu.c | 59 ++++++++++- configs/j7200_evm_a72_defconfig | 6 +- .../remoteproc/ti,k3-r5f-rproc.txt | 5 +- drivers/remoteproc/ti_k3_r5f_rproc.c | 99 +++++++++++++++++-- include/configs/j721e_evm.h | 14 ++- 8 files changed, 255 insertions(+), 15 deletions(-)
