Intel e7505: enable ECC scrubbing It takes about 3 seconds to scrub 8GiB DDR266 RAM. After ECC scrub XIP cache is disabled for system stability. There is very little to do in romstage after ECC scrub, especially when RAM debug messages are turned off. So the delay caused by this is hardly noticeable. Cache for complete ROM is re-enabled before ramstage is decompressed, and it has no unstability issues. So the code required to re-enable cache for ROM currently already exists in cache-as-ram_ht.inc. A Kconfig option HW_SCRUBBER enables the scrub to be run on hard reboots and power-ons.

Add support for E7505 northbridge. Adapted from northbridge/intel/e7501 with only minor changes. This commit provides minimal patch from e7501 and I prefer any cosmetic clean-up to be done after initial merge. Due the incomplete register specifications, it is safer to have e7505 as a separate directory in case I improve it to support wider range of memory configurations. I have no e7501 to test with.
