I found some comment pointing ar71xx and its routerboot.c and mach-rbspi.c as a reference for dynamic partition parsing. It has following advantages: 1) It dynamically finds beginning of hard coding partition 2) It dynamically finds beginning of soft coding partition and not much more. It assumes: 1) that bootloader starts at 0x0 2) there is nothing between bootloader & hard config 3) size of hard config partition 4) there is bios right after hard config partition 5) size of bios partition 6) (...) [I got tired by listing that] After all it seems routerboot.c + mach-rbspi.c also assume pretty fixed flash layout and I don't see it much much better over "fixed-partitions". Again, if we ever find "fixed-partitions" inaccurate it's something that can be changed. _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
