Attached is a diff between the trusty and trusty-proposed lshw output.
As you can see, the ECC capability is now shown.

Title:
lshw needs DDR3 support
Status in “lshw” package in Ubuntu:
Fix Released
Status in “lshw” source package in Trusty:
Fix Committed
Status in “lshw” package in Debian:
New
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.
