From df01714aec2dc4f8fb265fb3378adbbc128d7549 Mon Sep 17 00:00:00 2001 From: Joonyoung Shim Date: Thu, 24 Jun 2010 19:28:55 +0900 Subject: ARM: S5PV210: Fix Aquila board UART FIFO mode configration The Aquila board uses max UART FIFO size to each UART channels. UART0 supports 256 bytes FIFO, but Aquila board supports 128 bytes FIFO because of initial chip bug. Also, this patch fixes to "s/smdkv210/aquila".
