pstore/ram: Clarify resource reservation labels
When ramoops reserved a memory region in the kernel, it had an unhelpful
label of "persistent_memory". When reading /proc/iomem, it would be
repeated many times, did not hint that it was ramoops in particular,
and didn't clarify very much about what each was used for:
400000000-407ffffff : Persistent Memory (legacy)
400000000-400000fff : persistent_memory
400001000-400001fff : persistent_memory
...
4000ff000-4000fffff : persistent_memory
Instead, this adds meaningful labels for how the various regions are
being used:
400000000-407ffffff : Persistent Memory (legacy)
400000000-400000fff : ramoops:dump(0/252)
400001000-400001fff : ramoops:dump(1/252)
...
4000fc000-4000fcfff : ramoops:dump(252/252)
4000fd000-4000fdfff : ramoops:console
4000fe000-4000fe3ff : ramoops:ftrace(0/3)
4000fe400-4000fe7ff : ramoops:ftrace(1/3)
4000fe800-4000febff : ramoops:ftrace(2/3)
4000fec00-4000fefff : ramoops:ftrace(3/3)
4000ff000-4000fffff : ramoops:pmsg
