Neuschäfer" Convert the Freescale localbus controller bindings from text form to YAML. The list of compatible strings reflects current usage. Changes compared to the txt version: - removed the board-control (fsl,mpc8272ads-bcsr) node because it only appears in this example and nowhere else - added a new example with NAND flash Remaining issues: - The localbus is not really a simple-bus: Unit addresses are not simply addresses on a memory bus. Instead, they have a format: The first cell is a chip select number, the remaining one or two cells are bus addresses. Signed-off-by: J.
