I'm not sure about which generic functions we're supposed to use in replace of
get_field/set_field, at least as far as bitops.h goes. extract64/deposit64 has a
different API (it uses start bit + length, not a mask) and it would require
a lot of RISC-V code to be adapted to this format.
Looking a little further I see that registerfields.h has the equivalent of what
we're using here: FIELD_EX64 / FIELD_SEX64. But these macros seems to be tied
with
the abstractions used in the header, i.e. registers created with REG32/REG64 and
fields/masks created with the FIELD() macro. The header smmuv3-internal.h makes
use of them so we could use that as a base.
Hopefully Peter/Richard can correct me if I'm wrong and point to the right
direction. Thanks,
Yes, registerfields.h is the proper replacement.
