[Lenovo E325] DMIIllegalMappedAddrRange error when running FWTS

[Brendan Donegan]

When running the FWTS (Firmware Test Suite) we encountered the following error, classified as High importance:

FAILED [HIGH] DMIIllegalMappedAddrRange: Test 1, Illegal row position 00, while accessing entry
'Memory Device Mapped Address (Type 20)' @ 0xbf11f519, field 'Partial Row Position', offset 0x10

fwts is flagging up a DMI table field that is not strictly conforming to the DMI specification,

http://dmtf.org/sites/default/files/standards/documents/DSP0134_2.7.1.pdf

Section 7.21, page 93, offsect 10h, "Partition Row Postion" states:

"Identifies the position of the referenced Memory Device in a row of the address partition. For example, if two 8-bit devices form a 16-bit row, this field’s value is either 1 or 2.

The value 0 is reserved. If the position is unknown, the field contains FFh."

So, the firmware is using a reserved value of 0. We should expect unknown (0xff) or a value > 0.

This probably won't cause any issues with Linux, but it should be fed back to the BIOS vendor as a query or something to fix
on the next BIOS release
