Given that there now are quite a few additional "reserved" entries, and while we're still at SPL_HEADER_VERSION 1, I'd like to renew my request of dedicating one of these fields to the script length - which would enable us to set the U-Boot ${filesize} accordingly.
i.e. --- arch-arm-include-asm-arch-sunxi-spl.h +++ arch-arm-include-asm-arch-sunxi-spl.new.h @@ -49,7 +49,8 @@ uint8_t spl_signature[4]; }; uint32_t fel_script_address; - uint32_t reserved1[3]; + uint32_t fel_script_length; + uint32_t reserved1[2]; uint32_t boot_media; /* written here by the boot ROM */ uint32_t reserved2[5]; /* padding, align to 64 bytes */ };
I do not intend to further push my specific use cases, however I still consider the (then somewhat theoretical) ability to do "import -t ${fel_script_addr} ${filesize}" useful. For reference, the previous discussion related to this was somewhere around http://lists.denx.de/pipermail/u-boot/2015-September/227454.html
