- Fix a bug, where the bios memory map could have a bogus entry: according to R.B.'s Interrupt list, in some bioses the function for enumerating the memory can return ebx != 0 for the last descriptor, and fail in the following call returning CF = 1. In that case we were previously counting that last descriptor as well, but its content wouldn't describe a valid memory region.
- Use a static buffer for the bios memory map, stored in the achitecture specific file and return a pointer to that variable from PcMemGetMemoryMap. Reuse the static map from DetectAcpiBios instead of enumerating again. On arm, we don't even need a buffer, we return the pointer from the arm block.
