mmu: zero-extend paddr to match tval width (!539) · Merge requests · OpenHW Group / backup-20241120 / cva6

Eclipse Webmaster requested to merge github/fork/niwis/mmu-exception-width into master Oct 06, 2020

Created by: niwis

exception_t.tval is XLEN, while *_paddr is only PLEN wide. This results in an overflow of cause into tval and wrong exception information. Therefore, zero-extend physical addresses when assigned to lsu_exception_o.tval.
