(((Patch.header.cpuid == Processor’s CPUID) &&
((Patch.header.platformID & 2^FUSE_MSR[52:50]) != 0))
The MSR view of the EP80579 Platform ID is 100b. Table 8-1 summarizes the format of
the processor version identification signature (CPUID).

8.2.3
FSB Physical Interface
The IA-32 core replaces the standard bi-directional, tri-state FSB interface found on the
Pentium M processor (90nm) with a uni-directional interface. This uni-directional
interface is better suited for SoC applications that use a single core. This modification
replaces a single bi-directional wire with two uni-directional wires.
8.2.4
IA-32 Core and FSB Frequency
The EP80579 is targeted to operate with IA-32 core frequencies of 600 MHz, 1066 MHz
and 1200 MHz and FSB frequencies of 400 MHz (600 MHz SKU) and 533 MHz (1066
MHz and 1200 MHz SKUs).
