Hi,
On x86 various files that need to be created by binman. It does not make sense to enumerate these in the Makefile. They are described in the configuration (devicetree) for each board and we can simply run binman (always) to generate them.
Update the Makefile to have a separate, final step which runs binman, once all input dependencies are present.
This avoid sprinkling the Makefile with arch-specific code.
it seems that this patch (committed as 42b18df80fdb) breaks sunxi(!). When building current master, the Trusted Firmware binary does not make it into the u-boot-sunxi-with-spl.bin file. U-Boot still runs, but Linux won't get very far without BL31. To me it looks like we combine u-boot.img with the SPL, instead of u-boot.itb. Only the latter contains bl31.bin.
I bisected down into the hunks of this patch here, and by reverting just hunk #3 (the one introducing .binman_stamp) it works again. My knowledge of the U-Boot build system is somewhat limited, so I don't immediately see the problem or a fix.
A simple way to verify a build is complete would be: $ strings u-boot-sunxi-with-spl.bin | grep BL31 If it reports some lines, TF-A is included and it would work correctly. If it comes back empty, TF-A is missing and we won't boot.
I would be grateful for any insights!
Thanks for the info. Which board is this?
