#845 closed defect (fixed)

mvme2100 BSP has MMU disabled

Description

The 2100 BSP leaves the MMU off for data access (apparently intentionally). This is very bad (memory mapped devices) since all accesses without MMU are write-back caching enabled. There is a comment saying that the MMU is 'broken' -- however, I believe the problems that were observed are due to other bugs (incorrect/no MMU mapping was setup).

Release:
4.6.5, CVS head
