[PATCH 1/2] bsps/riscv: Remove inaccurate statement about reliance on a boot loader

[Hesham Almatary]

Hello,

I tried to push that but got an error message:
"remote: git_buildbot: ERROR: Could not connect to
buildbot.int.rtems.org:9899: Connection was refused by other side: 61:
Connection refused."

Please push if you're happy with the patch.

Cheers,
Hesham
