@ -129,7 +129,7 @@ Setting the ramoops parameters can be done in several different manners:
takes a size, alignment and name as arguments. The name is used
to map the memory to a label that can be retrieved by ramoops.
reserver_mem=2M:4096:oops ramoops.mem_name=oops
reserve_mem=2M:4096:oops ramoops.mem_name=oops
