Remove unsupported memory entry for the bcm7362 platform. The BMIPS4380 processor only supports ZONE_NORMAL is not available for HIGHMEM.

Hmm, this is more of a kernel limitation than a hardware limitation, though. The board physically has 1GB of memory, right? It is best if the DT entry reflects the actual hardware configuration. The Broadcom kernels enable the CPU's special "XKS01" feature to put 1GB of memory in ZONE_NORMAL: https://github.com/Broadcom/stblinux-3.3/tree/master/linux Maybe this would be worth adding to mainline. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
