There are two boot flow will use binman (socfpga_soc64_fit-u-boot.dtsi) to
generate u-boot.fit and kernel.fit:
1. socfpga_agilex_atf_defconfig (boot via ATF)
2. socfpga_agilex_vab_defconfig (boot via ATF with VAB enabled, support
authentication on bl31, u-boot, Linux images)
The binman node settings are the same for both flows. With VAB enabled, all
inputs file need to be signed before generate FIT image. We would like to use
different input file name to remind user that they need to sign all bl31,
u-boot, Linux images when using binman to generate FIT image.
Due to the binman node settings are identical and only the file name need to be
different, so we prefer to share the same socfpga_soc64_fit-u-boot.dtsi for
both flows.
Thanks,
Siew Chin
