-
- First 1 MiB of SDRAM is configured as secure region, other
- address spaces are non-secure regions. Only software executing
- at secure state EL3 (eg: U-boot SPL) and secure masters are
- allowed access to secure region.

+7. SDRAM secure region in U-boot ATF flow
+----------------------------------------------------------
+
+ In boot flow that uses ATF (ARM trusted firmware), the first 1 MiB of SDRAM
+ is configured as secure region, other address spaces are non-secure regions.
+ Only software executing at secure state EL3 (eg: U-boot SPL, ATF) and secure
+ masters are allowed access to the secure region.

+8. binman for U-boot ATF flow
+----------------------------------------------------------
+
+ Overview
+ ~~~~~~~~
+
+ Before v2021.04, we provide *.sh/*.its for user to generate FIT image using
+ 'mkimage' tool. To align with U-Boot community strategy to eliminate the custom
+ *.sh/*its script, we have removed all *.sh/*.its files and switched to use
+ 'binman' tool to generate FIT image for all SOC64 devices (Stratix 10, Agilex,
+ eASIC N5X) started in U-boot version v2021.04.
+
+ FIT image content is defined in binman node in U-boot device tree (u-boot.dtb).
+ U-Boot v2021.04 support u-boot.itb and kernel.itb.
+
+ With "CONFIG_BINMAN" enabled in deconfig, U-boot will always run 'binman' tool
+ before end of the code compilation. If the required input files exists in U-boot
+ folder, *.itb files defined in u-boot.dtb will be generated. Otherwise, 'binman'
+ will not generate the *.itb files. You can run 'binman' tool manually via command
+ line to generate the *.itb file.
+
+ Input Files
+ ~~~~~~~~~~~
+
+ Input files for *_atf_defconfig FIT image generation:
+ To generate u-boot.itb:
+ u-boot-nodtb.bin
+ u-boot.dtb
+ bl31.bin
+ To generate kernel.itb:
+ Image
+ linux.dtb
+
+ Input files for *_vab_defconfig FIT image generation:
+ To generate u-boot.itb:
+ signed-u-boot-nodtb.bin
+ signed-u-boot.dtb
+ signed-bl31.bin
+
+ To generate kernel.itb:
+ signed-Image
+ signed-linux.dtb
+
+ Command Line
+ ~~~~~~~~~~~~
+
+ Please use the following commands to generate the u-boot.itb and kernel.itb:
+
+ $ <U-boot path>/tools/binman/binman build -u -d u-boot.dtb -O .
+ This command generate all FIT images that defined in device tree.
+
+ $ <U-boot path>/tools/binman/binman build -u -d u-boot.dtb -O . -i u-boot
+ This command generate u-boot.itb only.
+
+ $ <U-boot path>/tools/binman/binman build -u -d u-boot.dtb -O . -i kernel
+ This command generate kernel.itb only.
