Well...it wasn't broken in next-20200720. A bit of poking with nm, and building hw_atl/hw_atl_b0.s, it looks like the culprit is this commit: commit 8dcf2ad39fdb2d183b7bd4307c837713e3150b9a Author: Mark Starovoytov <[email protected]> Date: Mon Jul 20 21:32:44 2020 +0300 net: atlantic: add hwmon getter for MAC temperature specifically this chunk around line 1634 of hw_atl/hw_atl_b0.c: + err = readx_poll_timeout_atomic(hw_atl_b0_ts_ready_and_latch_high_get, + self, val, val == 1, 10000U, 500000U); And doing a 'git revert' makes the build work....
