understanding -PIE about opensbi

[SiFiveHolland]

The OpenSBI firmware binary is no less bare metal because it is a PIE. OpenSBI applies relocations to itself as part of its entry assembly code, so there is no external dependency to load the firmware.

What problems do you experience when you don't patch OpenSBI?

Actually my toolchain does not support PIE. I should figure out how to rebuild with PIE if needed. That would be ok.

I appreciate the self relocation and I am a fan of flexibility. Just wondering if optional use of PIE (depending of toolchain capabilities) would be an option.

For me there is two options fork and patch or find I way to achieve both in the main repo, without need to fork - which is my preferred option. Thats why I am trying to understand if PIE could be optional.

(actually this is what I am doing)
