From mboxrd@z Thu Jan 1 00:00:00 1970 From: shawn.guo@linaro.org (Shawn Guo) Date: Tue, 14 Jun 2011 14:20:07 +0800 Subject: [PATCH v2 5/6] ARM: mxc: all three imx51 TOs use TO1 version of sdma script In-Reply-To: <1307950645-26529-6-git-send-email-shawn.guo@linaro.org> References: <1307950645-26529-6-git-send-email-shawn.guo@linaro.org> Message-ID: <1308032407-3860-1-git-send-email-shawn.guo@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Though there are three TOs of imx51 soc, the sdma script never changes since TO1, which means all three TOs of imx51 uses TO1 version of sdma script. The current code passes TO number to imx-sdma driver to load different firmware for different TO. That means we have to prepare 3 identical firmwares, sdma-imx51-to1.bin sdma-imx51-to2.bin and sdma-imx51-to3.bin, to have the kernel capable of running on all three TOs. This just makes no sense. The patch removes the TO number passing and get the default TO1 version of sdma firmware work for all TOs.
