Use SMBIOS_ENTRY_POINT_SCAN_START instead of 0xF0000, because other
archtecture maybe use a special start address such as 0xFFFE000 for
Loongson platform.

Hi Jean,

Since this patch is independent and it has no any negative influence,
could you apply it to your DMI tree first?

Thanks,

Tiezhu Yang

I've just queued your patch for kernel 5.6. Thanks for your
contribution and sorry for the delay.

Hi Jean,

Thank you very much, it has been merged into
mips-next and linux-next tree by Thomas about
three days ago, so you can drop it in your tree.

OK, I removed it from my dmi tree to avoid conflicts.
