i.mx8m plus arm trust zone

 

For i.MX 8M EVK, to build imx-boot image by using imx-mkimage, perform the following steps: 1. Copy and rename mkimage from u-boot/tools/mkimage to imx-mkimage/iMX8M/mkimage_uboot. 2. Copy u-boot-spl.bin from u-boot/spl/u-boot-spl.bin to imx-mkimage/iMX8M/. 3. Copy u-boot-nodtb.bin from u-boot/u-boot-nodtb.bin to imx-mkimage/iMX8M/. 4. Copy imx8mq-evk.dtb (for i.MX 8M Quad EVK), imx8mm-evk.dtb (for i.MX 8M Mini LPDDR4 EVK),      imx8mm-ddr4-evk.dtb (for i.MX 8M Mini DDR4 EVK), or      imx8mp-evk.dtb (for i.MX 8M Plus LPDDR4 EVK) from u-boot/arch/arm/dts/ to imx-mkimage/iMX8M/. 5. Copy bl31.bin from Arm Trusted Firmware (imx-atf) to imx-mkimage/iMX8M/. 6. Copy firmware/hdmi/cadence/signed_hdmi_imx8m.bin from the firmware-imx package to imx-mkimage/iMX8M/. 7. For i.MX 8M Quad and i.MX 8M Mini LPDDR4 EVK, copy lpddr4_pmu_train_1d_dmem.bin,      lpddr4_pmu_train_1d_imem.bin,     lpddr4_pmu_train_2d_dmem.bin, and     lpddr4_pmu_train_2d_imem.bin from firmware/ddr/synopsys of the firmware-imx package to imx-mkimage/ iMX8M/. For i.MX 8M Mini DDR4 EVK, copy     ddr4_imem_1d.bin,     ddr4_dmem_1d.bin,     ddr4_imem_2d.bin, and     ddr4_dmem_2d.bin from firmware/ddr/synopsys of the firmware-imx package to imx-mkimage/iMX8M. For i.MX 8M Plus LPDDR4 EVK, copy     lpddr4_pmu_train_1d_dmem_201904.bin,     lpddr4_pmu_train_1d_imem_201904.bin,     lpddr4_pmu_train_2d_dmem_201904.bin, and     lpddr4_pmu_train_2d_imem_201904.bin from firmware/ddr/synopsys of the firmware-imx package to imx-mkimage/iMX8M/. 8. For i.MX 8M Quad EVK, run make SOC=iMX8M flash_evk to generate flash.bin (imx-boot image) with HDMI FW included. For i.MX 8M Mini LPDDR4 EVK, run make SOC=iMX8MM flash_evk to generate flash.bin (imx-boot image). For i.MX 8M Mini DDR4 EVK, run make SOC=iMX8MM flash_ddr4_evk to generate flash.bin (imx-boot image). For i.MX 8M Plus LPDDR4 EVK, run make SOC=iMX8MP flash_evk to generate flash.bin (imx-boot-image). To boot with eMMC fasboot on i.MX 8M Quad EVK and i.MX 8M Mini LPDDR4 EVK, use flash_evk_emmc_fastboot target.
