From: Thor Thayer <tthayer@xxxxxxxxxxxxxxxxxxxxx>
In preparation for additional memory module ECCs, the IRQ and
check_deps() functions are being made available to all the memory
buffers. Move them outside of the OCRAM only area.
Signed-off-by: Thor Thayer <tthayer@xxxxxxxxxxxxxxxxxxxxx>
---
v2 New patch. Move shared functions outside OCRAM only area.
v3 Change title line - check_deps & IRQ.
v4 Replace #ifdeffery with __maybe_unused macro.
v5 No change
