[yocto] Enabling Ramdisk Support

[Crast, Nicholas]

All,

I am having some issues with initrd using u-boot and yocto. My current .config file in build/tmp/work/mitysom_5csx-poky-linux-gnueabi/linux-mitysom-5csx/3.12-r2/linux-socfpga-socfpga-3.12-7cb4fc4 has the following settings:

CONFIG_BLK_DEV_INITRD=y
CONFIG_INITRAMFS_SOURCE=""
CONFIG_RD_GZIP=y

Whenever I attempt to boot up with an initrd, I get a message saying that the kernel was unable to mount the rootfs. What concerns me, though, is I don't see any RAMDISK initialization messages on startup. Looking online, I figure I should see something like this:

[root]# dmesg | grep RAMDISK
RAMDISK driver initialized: 16 RAM disks of 4096K size 1024 blocksize


When I boot up, or at least some sort of error from RAMDISK. Is there a way I can verify that this option is actually being built into my system?

-Nick
