I don't know what's the current state of sdcard generation bbclass. 
However, I can assure you that it is not the most comofrtable
way of disk image generation. I would encourage you to switch to wic 
tool already instead (especially if you are using pyro revision).
An example wks file for i.MX SoC family can be found at: 
http://git.yoctoproject.org/cgit/cgit.cgi/meta-fsl-arm/tree/scripts/lib/image/canned-wks/imx-uboot-spl.wks

To enable it, you would need to add following lines to machine 
configuration file:

WKS_FILES = "imx-uboot-spl.wks"
IMAGE_DEPENDS_wic_append = " virtual/bootloader"
IMAGE_FSTYPES = "wic"
