> Hi,

> this series is adding support for full rela relocation.
> Origin NEEDS_MANUAL_RELOC option is still there as default.
>
> Code has been tested with multiple configurations on QEMU.
> - Origin behavior - u-boot
> - Relocated version - u-boot.elf
> - Loading u-boot.bin to higher address than TEXT_BASE
> - Loading u-boot.bin to lower address than TEXT_BASE
>
> In v2 I fixed Kconfig issue reported in v1 series.
>
> In v3 fix issues reported by gitlab CI.
>
> I incorrectly squashed m68k change to wrong patch. V4 fixes it.

> Thanks,

> Changes in v4:
> - Revert incorrect m68k merge - wrong patch
> - Aligned NEEDS_MANUAL_RELOC for m68k
>
> Changes in v3:
> - Move NEEDS_MANUAL_RELOC to m68k Kconfig to avoid Kconfig issues
>
> Changes in v2:
> - new patch in series to solve Kconfig warning
> - Fix endian selection
