From: Lee Jones <lee.jones@linaro.org>
Firmware can be loaded with a resource table, which details
resources needed by coprocessor like carevout memory, virtual
device, trace log buffer etc.
Until now, no method exists to display resource table content.
This function adds the capability to display the different
resources associated to a firmware if DEBUG is enabled.
