Instead of passing our own custom 32-bit addresses around and translating them, this patch makes all our register address constants absolute and removes the translation. There are two ugly parts: - fw_reg_addr() is needed to compute addresses of firmware registers, as this is dynamic based upon firmware - inc_addr() needs a small hack to handle byte vs word addressing However, both of those are only small, and we don't use fw_regs a whole lot anyway. The bonuses here include simplicity and improved driver readability. Also, the fact that registers are now referenced by 16-bit absolute addresses (as opposed to 32-bit pseudo addresses) means that over 2kb compiled code size has been shaved off. Includes some touchups and sparse fixes from Ulrich Kunitz. Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
