Subject: [PATCH v2 1/2] OMAP3 SDRC: Drop 133.3MHz, 66.6MHz rates from Qimonda SDRAM params file
Date: Thu, 14 May 2009 13:50:21 -0600	[thread overview]
Message-ID: <20090514195010.20623.21180.stgit@localhost.localdomain> (raw)
In-Reply-To: <20090514194728.20623.60039.stgit@localhost.localdomain>

Boards that used 133.3MHz maximum rate SDRAM were never released to the
public and presumably used the OMAPZoom kernel; so, drop these unused
rates.  Viz.:

    http://marc.info/?l=linux-omap&m=124232922426311&w=2

This patch is a collaboration between Richard Woodruff <r-woodruff2@ti.com>
and Paul Walmsley <paul@pwsan.com>.
