From 16c63f8ea49c3fcb9eac7ebc511f5c821d3c55c2 Mon Sep 17 00:00:00 2001 From: Daniel Walker Date: Tue, 30 Nov 2010 11:25:39 -0800 Subject: drivers: char: hvc: add arm JTAG DCC console support This driver adds a basic console that uses the arm JTAG DCC to transfer data back and forth. It has support for ARMv6 and ARMv7. This console is created under the HVC driver, and should be named /dev/hvcX (or /dev/hvc0 for example).
