[PATCH 12/25] hw/arm/mps2: Inline CMSDK_APB_TIMER creation |
Date: |
Thu, 21 Jan 2021 19:06:09 +0000 |
The old-style convenience function cmsdk_apb_timer_create() for
creating CMSDK_APB_TIMER objects is used in only two places in
mps2.c. Most of the rest of the code in that file uses the new
"initialize in place" coding style.
We want to connect up a Clock object which should be done between the
object creation and realization; rather than adding a Clock* argument
to the convenience function, convert the timer creation code in
mps2.c to the same style as is used already for the watchdog,
dualtimer and other devices, and delete the now-unused convenience
function.
