This only becomes an issue when __hyp_call_panic_nvhe() and
__hyp_call_panic_vhe() are moved to separate files, so I don't think it's
necessary to go in early.
Currently the string variable (declared static) is seen by the C compiler as
used by __hyp_call_panic_vhe(). But when split, the variable in the nVHE source
file becomes unused, is dropped by the compiler and the inline assembly's
reference is unresolved. We could then alias __hyp_text___hyp_panic_string back
to the VHE copy, but this is the right way of addressing it.
Thanks for the review,
David
