nrf52_bsim: Add replacement for nrfx's nrfx_coredep_delay_us() (4b50281f) · Commits · Wenxi XU / zephyr

Provide a replacement for this board for the nordic HAL nrfx nrfx_coredep_delay_us() This function is a busy wait, which in the HAL relies on the ARM DWT or assembler, but which in this board can just utilize the same busy_wait mechanism provided for k_busy_wait() Signed-off-by:
