Fix Object RAM clearing for CPS. Issue #561 #790

Closed paulb-nl closed 2 months ago

-Add ERASE_AW to clear 0x200000-0x2FFFFF. -SDRAM write mask was 2'b11 during erasing so it did not clear anything. -One small bug left: Last address is not written because erase_bsy goes low too early.

Thanks for spotting so many problems. Please give me a few days to study it.

Thank you. I have taken the ideas from here to implement it without the new ERASE_AW parameter, which would have affected many files and make the erase feature a bit less obvious. Please see e787541dd28c30798cb6e736a4b4d65e915f6dea
