Dynamic ATTR Override support via debug interface
-Supported by debug tools (ecmd-debug-framework/Cronus)
Only in istep mode and between isteps
Requires HB to be running
-Uses output of attributeOverride tool (same format as ATTR_TMP)
-Introduces two new "debug" isteps
255,4,set_attr_overrides
255,5,clear_attr_overrides
-Once istep is triggered Hostboot sends down address/size
and the debug tool uses putmempba to push data to cache/mem.
Then Hostboot consumes just like ATTR_TMP
