This is the 2nd version of patchset to Enable ARM Trusted Firmware for U-Boot.
New U-boot flow with ARM Trusted Firmware (ATF) support: SPL (EL3) -> ATF-BL31 (EL3) -> U-Boot Proper (EL2) -> Linux (EL1) SPL loads the u-boot.itb which consist of: 1) u-boot-nodtb.bin (U-Boot Proper image) 2) u-boot.dtb (U-Boot Proper DTB) 3) bl31.bin (ATF-BL31 image) Supported Platform: Intel SoCFPGA 64bits (Stratix10 & Agilex) Patch status: Have changes: Patch 2, 8, 9, 10, 11, 16 Other patches unchanged. Detail changelog can find in commit message. v1->v2: -------- Patch 2: - Move soc64 folder from board/altera to board/intel folder Patch 8: - Updated comments Patch 9: - Code clean up without functionality change Patch 10: - Code clean up without functionality change Patch 11: - Print error message and return instead of hang in socfpga_bridges_reset() when SMC call is failing. Patch 16: - Add CONFIG_SPL_LOAD_FIT_ADDRESS=0x02000000 - Move board/altera/soc64/fit_spl_atf.sh to board/intel/soc64/fit_spl_atf.sh History: -------- [v1]: https://patchwork.ozlabs.org/project/uboot/list/?series=195854 These patchsets have dependency on: arm: socfpga: soc64: Add timeout waiting for NOC idle ACK https://lists.denx.de/pipermail/u-boot/2020-August/423029.html Rename Stratix10 FPGA driver and support Agilex https://lists.denx.de/pipermail/u-boot/2020-August/422798.html SoCFPGA mailbox driver fixes and enhancements https://lists.denx.de/pipermail/u-boot/2020-August/423140.html arm: socfpga: soc64: Initialize timer in SPL only https://lists.denx.de/pipermail/u-boot/2020-July/419692.html arm: socfpga: soc64: Remove PHY interface setup from misc arch init https://lists.denx.de/pipermail/u-boot/2020-July/419690.html Enable sysreset support for SoCFPGA SoC64 platforms https://lists.denx.de/pipermail/u-boot/2020-August/422509.html arm: socfpga: soc64: Disable CONFIG_PSCI_RESET https://lists.denx.de/pipermail/u-boot/2020-August/423373.html Chee Hong Ang (16): arm: socfpga: soc64: Remove CONFIG_OF_EMBED arm: socfpga: soc64: Add FIT generator script for pack itb with ATF arm: socfpga: Add function for checking description from FIT image arm: socfpga: soc64: Load FIT image with ATF support arm: socfpga: soc64: Override 'lowlevel_init' to support ATF arm: socfpga: Disable "spin-table" method for booting Linux arm: socfpga: soc64: Add SMC helper function for Intel SOCFPGA (64bits) arm: socfpga: soc64: Define SMC function identifiers for PSCI SiP services mmc: dwmmc: socfpga: Add ATF support for MMC driver net: designware: socfpga: Add ATF support for MAC driver arm: socfpga: soc64: Add ATF support for Reset Manager driver arm: socfpga: soc64: Add ATF support for FPGA reconfig driver arm: socfpga: mailbox: Add 'SYSTEM_RESET' PSCI support to mbox_reset_cold() arm: socfpga: soc64: SSBL shall not setup stack on OCRAM arm: socfpga: soc64: Skip handoff data access in SSBL configs: socfpga: Add defconfig for Agilex and Stratix 10 with ATF support arch/arm/mach-socfpga/Kconfig | 2 - arch/arm/mach-socfpga/Makefile | 4 + arch/arm/mach-socfpga/board.c | 12 +- arch/arm/mach-socfpga/include/mach/smc_api.h | 13 + arch/arm/mach-socfpga/lowlevel_init_soc64.S | 76 +++ arch/arm/mach-socfpga/mailbox_s10.c | 5 + arch/arm/mach-socfpga/reset_manager_s10.c | 13 + arch/arm/mach-socfpga/smc_api.c | 56 ++ arch/arm/mach-socfpga/wrap_pll_config_s10.c | 3 +- board/intel/soc64/fit_spl_atf.sh | 92 ++++ ...ilex_defconfig => socfpga_agilex_atf_defconfig} | 23 +- configs/socfpga_agilex_defconfig | 1 - ...0_defconfig => socfpga_stratix10_atf_defconfig} | 25 +- configs/socfpga_stratix10_defconfig | 1 - drivers/fpga/intel_sdm_mb.c | 139 +++++ drivers/mmc/socfpga_dw_mmc.c | 26 +- drivers/net/dwmac_socfpga.c | 31 +- include/configs/socfpga_soc64_common.h | 9 + include/linux/intel-smc.h | 573 +++++++++++++++++++++ 19 files changed, 1071 insertions(+), 33 deletions(-) create mode 100644 arch/arm/mach-socfpga/include/mach/smc_api.h create mode 100644 arch/arm/mach-socfpga/lowlevel_init_soc64.S create mode 100644 arch/arm/mach-socfpga/smc_api.c create mode 100755 board/intel/soc64/fit_spl_atf.sh copy configs/{socfpga_agilex_defconfig => socfpga_agilex_atf_defconfig} (79%) copy configs/{socfpga_stratix10_defconfig => socfpga_stratix10_atf_defconfig} (79%) create mode 100644 include/linux/intel-smc.h -- 2.13.0
