Subject: [PATCH] [RFC] sh: kexec: Register crashk_res
Date: Fri, 02 Sep 2011 03:47:12 +0000 [thread overview]
Message-ID: <1314935232-1545-1-git-send-email-horms@verge.net.au> (raw)
Register crashk_res so that it can be used by kexec-tools
via /proc/iomem.
On x86 the registration occurs using
insert_resource(&iomem_resource, &crashk_res).
However that approach seems to result in the boot hanging on SH.
