+* Word alignment fixes for word aligned NS16550 UART
+ Patch by Jean-Paul Saman, 01 Mar 2005
+
+ Fixes bug with UART that only supports word aligned access: removed
+ "__attribute__ ((packed));" for "(CFG_NS16550_REG_SIZE == 4)" some
+ (broken!) versions of GCC generate byte accesses when encountering
+ the packed attribute regardless if the struct is already correctly
+ aligned for a platform. 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
