Author: bz Date: Sat Nov 7 16:35:48 2020 New Revision: 367451 URL: https://svnweb.freebsd.org/changeset/base/367451 Log: MFC r367327: arm64: implement bs_sr_<N> Implement the bs_sr_<N> generic functions based on the generic mips implementation calling the generic bs_w_<N> functions in a loop. ral(4) (rt2860.c) panics in RAL_SET_REGION_4() because bs_sr_4() is NULL. It seems ral(4) and ti(4) might be the only consumers of these functions I could find quickly so keeping them in C rather than asm.
