Peripherals that can only handle word + aligned access won't work properly when accessed with byte access. + The struct NS16550 is already word aligned for REG_SIZE = 4, so + there is no need to packed the struct in that case. + * Fix behaviour if gatewayip is not set Patch by Robin Gilks, 23 Dec 2004 |
