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.
Thanks, Michal
Changes in v2: - new patch in series to solve Kconfig warning - Fix endian selection
