Subject: [PATCHv2 1/5] xen: rename ns16550-uart.h to 8250-uart.h and fix some typos
Date: Wed,  7 Aug 2013 20:31:20 +0800	[thread overview]
Message-ID: <1375878685-24453-2-git-send-email-baozich@gmail.com> (raw)
In-Reply-To: <1375878685-24453-1-git-send-email-baozich@gmail.com>

Since UARTs on OMAP5 & Allwinner's SoC are not ns16550 but only 8250
compatible, rename ns16550-uart.h to 8250-uart.h, which is a more pervasive
name. At the same time, fix some typos, which have redundance UART_
prefixes in some macros.
