From: Kyösti Mälkki Date: Tue, 28 Feb 2012 12:01:34 +0000 (+0200) Subject: Apply cache-as-ram conditionally on socket mPGA604 X-Git-Url: http://wien.tomnetworks.com/gitweb/?p=coreboot.git;a=commitdiff_plain;h=abdf15f40b1e0838a43a54704ba5277c8210d69f Apply cache-as-ram conditionally on socket mPGA604 The socket mPGA604 is for P4 Xeon which to my knowledge is always HT-enabled. I assume the existing usage of car/cache_as_ram.inc on socket_mPGA604, namely the Tyan S2735, as broken. Existing car/cache_as_ram.inc has invalid SIPI vector and it does not initialise AP CPU's to activate L2 cache. Other mPGA604 boards are not affected, as they have not been converted to CAR.
