U-Boot typically sets up its malloc() pool near the top of memory. On ARM64 systems this can result in an SMBIOS table above 4GB which is not supported by SMBIOSv2.
Work around this problem by providing a new option to choose an address below 4GB (but as high as possible), if needed.
You must not overwrite memory controlled by the EFI subsystem without calling its allocator. We should provide SMBIOS 3. SMBIOS 2 is only a fallback for outdated tools.
That is not my intention and I don't believe this code does that. EFI is not running at this point, is it?
The bit I am confused about is that we don't support SMBIOS3 in U-Boot. I am trying to fix an introduced bug...
