Subject: [PATCH 04/11] of/flattree: eliminate cell_t typedef

From: Grant Likely <[email-masked]>
Date: Tue, 24 Nov 2009 01:18:35 -0700

A cell is firmly established as a u32.  No need to do an ugly typedef
to redefine it to cell_t.  Eliminate the unnecessary typedef so that
it doesn't have to be added to the of_fdt header file
