Above formula assumes the maximum HOB length could be 0xFFFF.
But actually the maximum HOB length could be only 0xFFF8 because
PeiCore::PeiCreateHob() contains following logic:
if (0x10000 - Length <= 0x7) {
return EFI_INVALID_PARAMETER;
}
Length = (UINT16)((Length + 0x7) & (~0x7));
The if-check is to guarantee (Length + 0x7) & ~0x7 doesn't produce value 0
when the Length > 0xFFF8.
So, that means the formula should use 0xFFF8 instead of 0xFFFF (MAX_UINT16).
