This is the 5th version of patchset to enable ARM Trusted Firmware for U-Boot for Intel Stratix10 and Agilex platform.
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)
Patch status: Have changes: Patch 7, 8, 9, 10, 16, 17 Other patches unchanged.
Detail changelog can find in commit message.
v4->v5: -------- Patch 7: - Change secure register access helper functions to return error code instead of hang the system if fail to access the secure register.
Patch 8: - Change designware MMC driver 'clksel' callback function to return the status. This patch is a preparation for enabling Arm-Trusted-Firmware (ATF) in Intel SoC FPGA. This patch does not change functionality.
Patch 9: - Report error if secure register access helper function failed to write SDMMC's DRVSEL and SMPLSEL via SMC call.
Patch 10: - Report error if secure register access helper function failed to write PHY register via SMC call.
patch 16: - Change 'blob' to 'blob-ext' entry in binman dts node for all input files.
patch 17: - Revert all changes about BINMAN in Makefile.
