EnforcePostVersion16PAL(
)
/*++
Routine Description:
This routine enforces that the system has a PAL version >= 20.
Note:
The return value from get PAL version call has the
PAL B model and revision has the least significant
16 bits (Intel IA-64 Architecture Software Developer's Manual, Rav. 1.0, Page 11-109).
We should be using this to determine a minimum PAL revision for the firmware.
The first byte has the PAL_B_revision which is a monotonically increasing number
and is 0x17 for Lion 71b and 0x20 for Softsur 103b.
The PAL_B model indicates the stepping of the processor supported (We can ignore this one).
So we need to be using PAL B revision for our minimum firmware test.
Just an FYI:
There is a disconnect in the PAL_REVISION structure and what appears to be the specified
PAL revision layout. We use PAL_B_REVISION to get the PAL version rather than PAL_A_REVISION.

None
Returns:
None
