Perhaps we should be doing that in qcom_defconfig if we aren't already.

Any update on this? This still seems to be the latest IFC6540 commit: https://git.linaro.org/landing-teams/working/qualcomm/kernel.git/commit/66c04e30f4a6e6ed998a6c154a6c45b3cd5b3fde Following the instructions in https://wiki.linaro.org/Boards/IFC6540 I've tried to pass a full rootfs as ramdisk parameter (fastboot boot -c "console=ttyMSM0,115200,n8 rw rootwait" -b 0x0 zImage-ifc6540 initrd.cpio.gz), but I then get: [258660] fastboot: download:12738800 [268150] fastboot: boot [268150] kernel/ramdisk addresses overlap with aboot addresses. Booting without ramdisk specified works, but for lack of SD, USB and network support I then have no root. So, do you have any new insights on why 'status = "okay";' doesn't work for the above sdhci node? Or do you have a working config you can share for creating a non-overlapping abootimg?

Enable support for the two SD host controllers on the APQ8084 platform by adding the required nodes to the DT files. On the IFC6540 board, the first controller is connected to the onboard eMMC and the second is connected to a micro-SD card slot.
