From 9f29aeb89de8199ebaea9995dbb30ea5fa2f1085 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Wed, 13 Jan 2016 19:38:58 -0800 Subject: Revert "fdt_support: Add multi-serial support for stdout fixup" This reverts commit 3e303f748cf57fb23e8ec95ab7eac0074be50e2b. The fix up in the /aliases node does not work under the following scenarios: - Not every non-DM serial driver was written to have a driver name that conforms the format of "serial%d" or "eserial%d". - With driver model serial, the stdio_devices[] stores the serial device node name in the device tree.
