From 4b17645d5d60a9aa8ef0810d4fdf962bce407c8a Mon Sep 17 00:00:00 2001 From: Daniel Schwierzeck Date: Sat, 12 Jan 2013 18:18:20 +0100 Subject: [PATCH] MIPS: bootm: drop obsolete Qemu specific bootm implementation The Qemu specific bootm implementation was intended for a special Qemu target in Linux kernel. But this target has been dropped in v2.6.25-rc1 by commit 302922e5f6901eb6f29c58539631f71b3d9746b8 Author: Ralf Baechle Date: Tue Jan 29 10:15:02 2008 +0000 [MIPS] Qemu: Remove platform. The Qemu platform was originally implemented to have an easily supportable platform until Qemu reaches a state where it emulates a real world system. Since the latest release Qemu is capable of emulating the MIPSsim and Malta platforms, so this goal has been reached. The Qemu plaform is also rather underfeatured so less useful than a Malta emulation. Thus the special bootm implementation is obsolete by now and can be dropped. The Qemu support in U-Boot is going to be replaced by MIPS Malta board support.
