Not exactly misspelled... I renamed them myself in the ELF relocation patch -- which means your arch/arm/include/asm/u-boot-arm.h is that of the elf_reloc branch -- which means your board.c is not up to date. > Adding _bss_start + _armboot_start into u-boot-arm.h makes it > compile nicely :) Big thanks. > Still cant understand why it showed up now and > not in my e79f48393dd919079b34f37957c933f8e75c164d revision(from 13th of > october). > And also why people with arm boards arent hitting this all the time, or is > everyone running with relocation already? Everyone should be. Now is a transition period where ARM board owners must support (ELF) relocation or else the boards are going to be removed, IIUC. > Anyhow, the quick fix in case someone needs it: This is not a quick fix; this is a workaround to a weird source tree issue. Either you should build on the master branch (and then your .h file should already have _bss_start and _armboot_start or you build on the elf_reloc branch and should not refer to _bss_start and _armboot_start but to their _ofs counterparts throughout the code; you can look up how this is done on arm926ejs.
