[U-Boot] [PATCH] armv8: ls2080a: update fdt path for fsl-mc node

From: Stuart Yoder <redacted>

The fsl-mc node has been moved under /soc, so update
the path references accordingly.  Backwards compatibility
is retained for /fsl-mc.

Delete backwards compatibility for the completely obsolete
/fsl,dprc at 0.

As you can see in the patch, we first check /soc/fsl-mc.  If that is not
there we check /fsl-mc.  So, both will work.

Use of /fsl,dprc at 0 I think was Freescale-internal only and there is
no actual use of it remaining.

Prabhakar,

Are you OK with Stuart's answer?

Applied to u-boot-fsl-qoriq master. Awaiting upstream.

Thanks.
