This patch renames the board directory from board/freescale to board/nxp because NXP now provides Board Support Packages (BSPs) and tools for the former Freescale i.MX and other i.MX products. All relevant references have been updated accordingly. This change does not affect functionality. Signed-off-by: Alice Guo <alice.guo@nxp.com> Reviewed-by: Fabio Estevam <festevam@gmail.com>
