Subject: [PATCH/RFC 04/17] MIPS: BMIPS: Allow BMIPS3300 to utilize SMP ebase relocation code
Date: Mon, 20 Oct 2014 21:27:54 -0700 [thread overview]
Message-ID: <1413865687-15255-5-git-send-email-cernekee@gmail.com> (raw)
In-Reply-To: <1413865687-15255-1-git-send-email-cernekee-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
From: Jon Fraser <jfraser-dY08KVG/lbpWk0Htik3J/w@public.gmane.org>
BMIPS3300 processors do not have the hardware to support SMP, but with a
small tweak, the SMP ebase relocation code allows BMIPS3300-based
platforms to reuse the S2/S3 power management code from BMIPS4380-based
chips. Normally this is as simple as adding one line to prom_init():
board_ebase_setup = &bmips_ebase_setup;
