The current FitGen has "-NA" parameter to indicate whether microcode
is placed with an alignment, but it could only support 0x800 alignment:
- With"-NA" means microcode is not aligned.
- No "-NA" means Microcode is 0x800 aligned.
There is no method to specify other alignment value.
This patch add "-A" option to FitGen for to configure the alignment
to a user specified value. The change is backward compatible as:
- Only "-NA" means microcode is not aligned (same as before).
- No "-NA" and No "-A" means Microcode is 0x800 aligned (same as
before).
- Only "-A" means microcode is aligned with specified value (new).
