Exists in smarc-l5.0.0_1.0.0-ga and in 5 other branches imx_3.10.17_1.0.1_ga, imx_3.10.53_1.1.0_ga, imx_3.14.28_1.0.0_ga, smarc-imx_3.10.53_1.1.0_ga, smarc-imx_3.14.28_1.0.0_ga

edac: add a new memory layer type 

There are some cases where the memory controller layout is
completely hidden. This is the case of firmware-driven error
code, like the one provided by GHES. Add a new layer to be
used on such memory error report mechanisms.
