On ARM it's relevant to not only distinguish between ordinary cached memory
and write-combined one, but also having non-cached memory too. To insert the
appropriated page table entries e.g.: in the base-hw kernel, we need to preserve
the information about the kind of memory from allocation until the pager
resolves a page fault. Therefore, this commit introduces a new Cache_attribute
type, and replaces the write_combined boolean with the new type where necessary.
In case the storage-entry point dispatches more then one packet, wait for the
previous command to finish before setting a new request. This has to be done
because the 'queuecommand' does actually *not* queue things, but can only handle
one request at the time.
