Hi, I am looking at the redboot packages/hal/arm/mx31/3stack/current/include/hal_platform_setup.h in the latest PDK 1.4 released by Freescale for the MX31. I am trying to understand what do the following lines do using the GPIO3 pin. Are they in anyway related to the enabling the SD host controller driver. I am trying to relate it to the init sequence for SDHC on the PDK board. Appreciate your help! Thanks, Alfred.
