Subject: [PATCH] Enhance FitGen
1) Fix alignment issue for FV header
2) Will check each size of uCode patch is less than SlotSize
3) Will continue to scan empty slot after uCode patch array
Assumption: there are no empty slot between each uCode patch
The empty range is behind uCode patch array
4) We reserve 100KB for each uCode patch in current solution

And, you also need to update BZ https://bugzilla.tianocore.org/show_bug.cgi?id=2321 for this change.
Based on current description in BZ, I don't know why need to add -S option.

Newer version.
Add -L/-l for Microcode slot mode.
Hi Vincent, Pls follow this to change the usage in postbuild.bat when generating BIOS image.
Thanks, Kenji.

Kenji:
This patch adds -S option for Slotsize. Please update FitGen tool help message to list this new option.
And, you also need to update BZ https://bugzilla.tianocore.org/show_bug.cgi?id=2321 for this change.
Based on current description in BZ, I don't know why need to add -S option.
Thanks
Liming

Newer version.
Add -L/-l for Microcode slot mode.
Hi Vincent, Pls follow this to change the usage in postbuild.bat when generating BIOS image.
Thanks, Kenji.

Kenji:
This patch adds -S option for Slotsize. Please update FitGen tool help message to list this new option.
And, you also need to update BZ https://bugzilla.tianocore.org/show_bug.cgi?id=2321 for this change.
Based on current description in BZ, I don't know why need to add -S option.
Thanks
Liming
