** Description changed:
- lshw currently assumes memory described by device-tree is DDR2, which
- makes assumptions invalid for DDR3.
-
- Specifically, it is unable to detect ecc and spd capabilities.
+ [Impact]
+ lshw currently assumes memory described by device-tree is DDR2, which makes assumptions invalid for DDR3.
+ Specifically, it is unable to detect ecc and spd capabilities - so things like ECC support are not exposed.
+ [Test Case]
+ Run lshw on a device-tree-based system with DDR3 RAM and observe that no ECC capability is shown
+ [Regression Potential]
+ Because this changes how the output for DDR2 ram is generated, there is a potential that the expected output changes on existing device-tree based systems with DDR2.

Bug description:
[Impact]
lshw currently assumes memory described by device-tree is DDR2, which makes assumptions invalid for DDR3.
Specifically, it is unable to detect ecc and spd capabilities - so things like ECC support are not exposed.
[Test Case]
Run lshw on a device-tree-based system with DDR3 RAM and observe that no ECC capability is shown
[Regression Potential]
Because this changes how the output for DDR2 ram is generated, there is a potential that the expected output changes on existing device-tree based systems with DDR2.
