+How to Update U-Boot on imx6ulz_smm_m2 board
+--------------------------------------------
+
+Required software on the host PC:
+
+- UUU: https://github.com/NXPmicro/mfgtools
+
+Build U-Boot for m2:
+
+$ make mrproper
+$ make imx6ulz_smm_m2_defconfig
+$ make
+
+This generates the SPL and u-boot-dtb.img binaries.
+
+1. Loading U-Boot via USB Serial Download Protocol
+
+Copy SPL and u-boot-dtb.img to the uuu folder.
+
+Load the U-Boot via USB:
+
+$ sudo uuu -v -b nand_script.lst u-boot-with-spl.imx
+
+where nand_script.lst contains the following:
+
+uuu_version 1.2.39
+
+# @_flash.bin            | bootloader
+# @_image   [_flash.bin] | image burn to nand, default is the same as bootloader
+
+# This command will be run when i.MX6/7 i.MX8MM, i.MX8MQ
+SDP: boot -f _flash.bin
+
+# This command will be run when ROM support stream mode
+# i.MX8QXP, i.MX8QM
+SDPS: boot -f _flash.bin
+
+# These commands will be run when use SPL and will be skipped if no spl
+# SDPU will be deprecated. please use SDPV instead of SDPU
+# {
+SDPU: delay 1000
+SDPU: write -f _flash.bin -offset 0x57c00
+SDPU: jump
+# }
+
+# These commands will be run when use SPL and will be skipped if no spl
+# if (SPL support SDPV)
+# {
+SDPV: delay 1000
+SDPV: write -f _flash.bin -offset 0x11000
+SDPV: jump
+# }
+
+FB: ucmd setenv fastboot_buffer ${loadaddr}
+FB: download -f _image
+FB: ucmd if test ! -n "$fastboot_bytes"; then setenv fastboot_bytes $filesize; else true; fi
+# Burn image to nandfit partition if needed
+FB: ucmd if env exists nandfit_part; then nand erase.part nandfit; nand write ${fastboot_buffer} nandfit ${fastboot_bytes}; else true; fi;
+FB: ucmd nandbcb init ${fastboot_buffer} nandboot ${fastboot_bytes}
+FB: Done
+
+Then U-Boot starts and its messages appear in the console program.
+
+Use the default environment variables:
+
+=> env default -f -a
+=> saveenv

+      +=========================================================+
+      +  i.MX8M U-Boot HABv4 Secure Boot guide for SPL targets  +
+      +=========================================================+
+
+1. HABv4 secure boot process
+-----------------------------
+
+This document is an addendum of mx6_mx7_spl_secure_boot.txt guide describing
+a step-by-step procedure on how to sign and securely boot an U-Boot image for
+SPL targets on i.MX8M, i.MX8M Mini, i.MX8M Nano, i.MX8M Plus.
+
+Details about HAB can be found in the application note AN4581[1] and in the
+introduction_habv4.txt document.
+
+1.1 Building a SPL target supporting secure boot
+-------------------------------------------------
+
+The U-Boot build for i.MX8M SoC makes use of Second Program Loader (SPL)
+support, fitImage support and custom i.MX8M specific flash.bin container.
+This leads to a generation of multiple intermediate build artifacts, the
+U-Boot SPL, U-Boot binary, DT blob. These later two artifacts are bundled
+with external ATF BL31 blob to form a fitImage. The fitImage is bundled
+with SPL and external DDR and optional HDMI PHY initialization blobs to
+form the final flash.bin container. The HABv4 can be used to authenticate
+all of the input binaries separately.
+
+Out of reset the ROM code authenticates the SPL and PHY initialization
+blobs, combination of which is responsible for initializing essential
+features such as DDR, UART, PMIC and clock enablement. Once the DDR is
+available, the SPL code loads the secondary fitImage to its specific
+address and call the HAB APIs to extend the root of trust on its
+components.
+
+The U-Boot SPL provides support to secure boot configuration and also
+provide access to the HAB APIs exposed by the ROM vector table, the
+U-Boot provides access to HAB APIs via SMC calls to ATF. The support
+is enabled by selecting the CONFIG_IMX_HAB option.
+
+When built with this configuration the U-Boot correctly pads combined
+SPL and PHY initialization blob image, called u-boot-spl-ddr.bin, by
+aligning to the next 0xC00 address, so the CSF signature data generated
+by CST can be concatenated to the image.
+
+The U-Boot also reserves space in the fitImage binary (u-boot.itb) between
+the fitImage tree and external blobs included in it, so it can be used to
+inject IVT and CST signatures used by SPL HAB calls to authenticate the
+fitImage components.
+
+The diagram below illustrate a signed SPL combined with DDR PHY
+initialization firmware blobs part of flash.bin container layout.
+This part is loaded to memory address ( CONFIG_SPL_TEXT_BASE - 0x40 ) and
+authenticated the BootROM. The reason for the offset is so that the *entry
+would be at memory address CONFIG_SPL_TEXT_BASE when BootROM executes the
+code within it:

+
+1.2 Enabling the secure boot support
+-------------------------------------
+
+The first step is to generate an U-Boot image supporting the HAB features
+mentioned above, this can be achieved by adding CONFIG_IMX_HAB to the
+build configuration:
+
+- Defconfig:
+
+  CONFIG_IMX_HAB=y
+
+- Kconfig:
+
+  ARM architecture -> Support i.MX HAB features
+
+1.3 Signing the images
+-----------------------
+
+The CSF contains all the commands that the HAB executes during the secure
+boot. These commands instruct the HAB code on which memory areas of the image
+to authenticate, which keys to install, use and etc.
+
+CSF examples are available under doc/imx/habv4/csf_examples/ directory.
+
+CSF "Blocks" line for csf_spl.txt can be generated as follows:
+
+```
+spl_block_base=$(printf "0x%x" $(( $(sed -n "/CONFIG_SPL_TEXT_BASE=/ s@.*=@@p" .config) - 0x40)) )
+spl_block_size=$(printf "0x%x" $(stat -tc %s u-boot-spl-ddr.bin))
+sed -i "/Blocks = / s@.*@  Blocks = $spl_block_base 0x0 $spl_block_size \"flash.bin\"@" csf_spl.txt
+```
+
+The resulting line looks as follows:
+```
+  Blocks = 0x7e0fc0 0x0 0x306f0 "flash.bin"
+```
+
+The columns mean:
+  - CONFIG_SPL_TEXT_BASE - 0x40 -- Start address of signed data, in DRAM
+  - 0x0 -- Start address of signed data, in "flash.bin"
+  - 0x306f0 -- Length of signed data, in "flash.bin"
+  - Filename -- "flash.bin"
+
+To generate signature for the SPL part of flash.bin container, use CST:
+```
+cst -i csf_spl.tmp -o csf_spl.bin
+```
+
+The newly generated CST blob has to be patched into existing flash.bin
+container. Conveniently, flash.bin IVT contains physical address of the
+CSF blob. Remember, the SPL part of flash.bin container is loaded by the
+BootROM at CONFIG_SPL_TEXT_BASE - 0x40 , so the offset of CSF blob in
+the fitImage can be calculated and inserted into the flash.bin in the
+correct location as follows:
+```
+# offset = IVT_HEADER[6 = CSF address] - CONFIG_SPL_TEXT_BASE - 0x40
+spl_csf_offset=$(xxd -s 24 -l 4 -e flash.bin | cut -d " " -f 2 | sed "s@^@0x@")
+spl_bin_offset=$(xxd -s 4 -l 4 -e flash.bin | cut -d " " -f 2 | sed "s@^@0x@")
+spl_dd_offset=$((${spl_csf_offset} - ${spl_bin_offset} + 0x40))
+dd if=csf_spl.bin of=flash.bin bs=1 seek=${spl_dd_offset} conv=notrunc
+```
+
+CSF "Blocks" line for csf_fit.txt can be generated as follows:
+```
+# fitImage tree
+fit_block_base=$(printf "0x%x" $(( $(sed -n "/CONFIG_SYS_TEXT_BASE=/ s@.*=@@p" .config) - $(sed -n "/CONFIG_FIT_EXTERNAL_OFFSET=/ s@.*=@@p" .config) - 0x200 - 0x40)) )
+fit_block_offset=$(printf "0x%s" $(fdtget -t x u-boot.dtb /binman/imx-boot/uboot offset))
+fit_block_size=$(printf "0x%x" $(( ( $(fdtdump u-boot.itb 2>/dev/null | sed -n "/^...totalsize:/ s@.*\(0x[0-9a-f]\+\).*@\1@p") + 0x1000 - 0x1 ) & ~(0x1000 - 0x1) + 0x20 )) )
+sed -i "/Blocks = / s@.*@  Blocks = $fit_block_base $fit_block_offset $fit_block_size \"flash.bin\", \\\\@" csf_fit.tmp
+
+# U-Boot
+uboot_block_base=$(printf "0x%s" $(fdtget -t x u-boot.itb /images/uboot load))
+uboot_block_offset=$(printf "0x%x" $(( $(printf "0x%s" $(fdtget -t x u-boot.itb /images/uboot data-position)) + ${fit_block_offset} )))
+uboot_block_size=$(printf "0x%s" $(fdtget -t x u-boot.itb /images/uboot data-size))
+sed -i "/0xuuuu/ s@.*@           $uboot_block_base $uboot_block_offset $uboot_block_size \"flash.bin\", \\\\@" csf_fit.tmp
+
+# ATF
+atf_block_base=$(printf "0x%s" $(fdtget -t x u-boot.itb /images/atf load))
+atf_block_offset=$(printf "0x%x" $(( $(printf "0x%s" $(fdtget -t x u-boot.itb /images/atf data-position)) + ${fit_block_offset} )))
+atf_block_size=$(printf "0x%s" $(fdtget -t x u-boot.itb /images/atf data-size))
+sed -i "/0xaaaa/ s@.*@           $atf_block_base $atf_block_offset $atf_block_size \"flash.bin\", \\\\@" csf_fit.tmp
+
+# DTB
+dtb_block_base=$(printf "0x%x" $(( ${uboot_block_base} + ${uboot_block_size} )))
+dtb_block_offset=$(printf "0x%x" $(( $(printf "0x%s" $(fdtget -t x u-boot.itb /images/fdt-1 data-position)) + ${fit_block_offset} )))
+dtb_block_size=$(printf "0x%s" $(fdtget -t x u-boot.itb /images/fdt-1 data-size))
+sed -i "/0xdddd/ s@.*@           $dtb_block_base $dtb_block_offset $dtb_block_size \"flash.bin\"@" csf_fit.tmp
+```
+
+The fitImage part of flash.bin requires separate IVT. Generate the IVT and
+patch it into the correct aligned location of flash.bin as follows:
+```
+# IVT
+ivt_ptr_base=$(printf "%08x" ${fit_block_base} | sed "s@\(..\)\(..\)\(..\)\(..\)@0x\4\3\2\1@")
+ivt_block_base=$(printf "%08x" $(( ${fit_block_base} + ${fit_block_size} - 0x20 )) | sed "s@\(..\)\(..\)\(..\)\(..\)@0x\4\3\2\1@")
+csf_block_base=$(printf "%08x" $(( ${fit_block_base} + ${fit_block_size} )) | sed "s@\(..\)\(..\)\(..\)\(..\)@0x\4\3\2\1@")
+ivt_block_offset=$((${fit_block_offset} + ${fit_block_size} - 0x20))
+csf_block_offset=$((${ivt_block_offset} + 0x20))
+
+echo "0xd1002041 ${ivt_ptr_base} 0x00000000 0x00000000 0x00000000 ${ivt_block_base} ${csf_block_base} 0x00000000" | xxd -r -p > ivt.bin
+dd if=ivt.bin of=flash.bin bs=1 seek=${ivt_block_offset} conv=notrunc
+
+To generate CSF signature for the fitImage part of flash.bin container, use CST:
+```
+cst -i csf_fit.tmp -o csf_fit.bin
+```
+
+Finally, patch the CSF signature into the fitImage right past the IVT:
+```
+dd if=csf_fit.bin of=flash.bin bs=1 seek=${csf_block_offset} conv=notrunc
+```
+
+The entire script is available in doc/imx/habv4/csf_examples/mx8m/csf.sh
+
+1.4 Closing the device
+-----------------------
+
+The procedure for closing the device is similar as in Non-SPL targets, for a
+complete procedure please refer to section "1.5 Programming SRK Hash" in
+mx6_mx7_secure_boot.txt document available under doc/imx/habv4/guides/
+directory.
