From 6ec006ede5e0526c20cd7ed5e20df637ea592b1f Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Mon, 12 Aug 2013 14:09:28 -0400 Subject: tilegx: provide kernel support for the tilegx UART shim The TILE-Gx chip includes an on-chip UART. This change adds support for using the UART from within the kernel. The UART shim has more functionality than is exposed here, but to keep the kernel code and binary simpler, this is a subset of the full API designed to enable a standard Linux tty serial driver only.
