OBSOLETES: From: Jean-Paul Saman Date: 23-02-2005 Subject: [PATCH] word alignment fixes for word aligned NS16550 UART peripheral
CHANGELOG: * Patch by Jean-Paul Saman, 23 Feb 2005
- include/ns16550.h Fixes alignement bug with UART that only supports word aligned access: removed "__attribute__ ((packed));" for "(CFG_NS16550_REG_SIZE == 4)" GCC generates bytes access when it encounters the packed attribute regardless if the struct is already word 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.
