This follows the example of RISC-V where <asm/global_data.h> includes <asm/u-boot.h> directly as "gd" includes a reference to bd_info already and so the first must include the second anyhow. We then remove <asm/u-boot.h> from all of the places which include references to "gd" an so have <asm/global_data.h> already. Signed-off-by: Tom Rini <trini@konsulko.com>
