PS1, Line 11: This reduction along with the available free space in PSP shared buffer
            : (32 KiB)
> That backup space is in MP2 SRAM and not in PSP's SRAM. So PSP has to work with their MP2 FW team and still bump it up.
>
> Also if you look at the layout closely, Bootblock, ROM Stage, FSP-M also closely follow PSP_SHARED_MEM. So they need to be moved around which needs a revisit of memory map.
>
> I have tried increasing the PSP_SHARED_MEM size without any corresponding PSP FW changes. The system ended up not booting.

got it. Thanks for explaining that!
