of --append option for both set and append the STRING at the cmdline.
With this patch we correctly
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.

Hi,
This is version 2 of the patch
Changes from Version 1 :
: Changed the interface for read_memory_region_limits to use 'int fd'
