The analog input pins on the Intel Galileo board are not enabled in Wind River Linux 5. Enabling with AD:7298 in the Kernel does not enable the pins. These are pins A0-A5 on the board, internally mapped in Linux to 44-49. They are Muxed with AD:7298.

Steps to Reproduce

Build an Intel-Quark platform project (glibc-small or glibc-IDP), and boot it on the Intel Galileo board with a micro-SD card. After boot, the pins are not accessable, and to not appear activated under /sys/kernel/debug/gpio.
