Please drop this as it is not needed. *gd is zeroed on start.

[PATCH v2] board_f: Copy GD to new GD even if relocation disabled

2021-10-15 Thread marek . vasut
From: Marek Vasut 

Even if U-Boot has relocation disabled via GD_FLG_SKIP_RELOC , the
relocated stage of U-Boot still picks GD from new_gd location. The
U-Boot itself is not relocated, but GD might be, so copy the GD to
new GD location even if relocation is disabled.
