Ross Thompson	de9e234ffa	Modified icache to no longer need StallF in the PCMux logic. Instead this is handled in the icachefsm. ... One downside is it increases the icache complexity. However it also fixes an untested bug. If a region was uncacheable it would have been possible for the request to be made multiple times. Now that is not possible. Additionally spills were oscillating between the spill hit states without this change. The impact was 'benign' as the final spilled instruction always had the correct upper 16 bits.	2021-08-27 11:03:36 -05:00
