Dear Albert ARIBAUD, >>> ATM on mainline master branch only five ARM cpus (arm926ejs, arm1136, >>> arm1176, armv7 and pxa) have ELF relocation support. Others still use >>> GOT relocation (or the older fixed-location scheme maybe), which IIUC >>> means all boards using these other cpus are broken unless a maintainer >>> gets patches pulled in to support ELF relocs. >>> >>> I therefore propose that V5 of my patch fixes arm926ejs, armv7, arm1136, >>> arm1176 and pxa only, and leave the ten other ARM cpus untouched. Board >>> maintainers who want to fix their board support for ELF relocs may have >>> to also fix their cpu if it is not yet. >>> >>> Does everyone agree? >> I dislike having such a mix of different relocation methods. >> >> Let's face it: this discussion has been going on for so long already >> that every interested party could have adapted their code.

Is that ok?
Would it not be "nice" to take the ARM-universal identical code for relocate, clear bss and transfer to relocated code out of each ARM/CPU/*/start.S and move it to ARM/LIB/relocate.S ? You would not have to duplicate and maintain that code in every ARM CPU type. That would also pave the path to the relocation in C which I have started a while ago.
