Subject: OMAP baseline test results for v3.15-rc8

From: [email-masked] (Dmitry Lifshitz)
Date: Mon, 02 Jun 2014 11:45:47 +0300

Hi Paul,

CM-T3517 is a bare-bone CoM without MMC/SD card slot (NAND option).
MMC/SD card interface (and some other peripherals) are properties of the 
carrier base board SB-T35, which turns this CoM into fully functional 
board SBC-T3517.

Please, use omap3-sbc-t3517.dtb target.

Attached Linux v3.15-rc8 boot log using omap2plus_defconfig.
