[SeaBIOS] POST Memory Manager emulation in SeaBIOS

[Darmawan Salihun]

Hi Kevin,

I finally got everything I needed with SeaBIOS debug level set to 8.

These are the relevant snippets from the serial logging:
-------------------------------------------
Scan for option roms

-------------------------------------------
What I really needed is the details about the  memory allocated
by SeaBIOS for the PMM call in the option rom (test.rom above).
Particularly, start address of the allocated memory.

Thank you very much for your help

Kind Regards,

Darmawan
