[U-Boot] [PATCH v3 15/19] ARM: tegra: Enable position independent build for 64-bit

Thierry Reding
2019-03-21T18:01:14Z

Note that U-Boot is always chainloaded from cboot starting with L4T
release 28. cboot always loads U-Boot to a fixed address, so making
the builds position independent isn't strictly necessary. However,
position independent builds can be convenient because if U-Boot is
ever loaded to an address different from its link address, it will
still be able to boot.
