From mboxrd@z Thu Jan 1 00:00:00 1970 From: swirl@gmx.li (Thomas Weber) Date: Thu, 25 Feb 2010 10:36:13 +0100 Subject: No subject Message-ID: <1267090573-17708-1-git-send-email-swirl@gmx.li> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Subject: [PATCH/RFC] OMAP2: serial.c: Fix number of uarts in early_init The omap_serial_early_init prints the following errors: Could not get uart4_ick Could not get uart4_fck because all the uarts available in omap_uart[] will be initialized. Only omap4430 and omap3630 have 4 uarts at the moment. This patch reduces the number of uarts when cpu is not omap4430 or omap3630.
