Store the memory region ID in the memory descriptor structure. This is a move toward *not* indexing the array by the ID, but for now we must still specify those index values. Define an explicitly undefined region ID, value 0, so uninitialized entries in the array won't use an otherwise valid ID. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.
