[meta-freescale] SD card image for LS1021a

[Thomas T]

Hi,

I tried to add support for sd card image generation (enable
IMAGE_FSTYPES="sdcard" in fsl-image-full.bb) to the SDK1.7.

Based on the file image_types_fsl.bbclass I want to creat a file
image_types_ls1.bbclass. To make bitbake aware of the new file I assume I
have to add "IMAGE_CLASSES += "image_types_ls1"" to the file
fsl-default-settings.inc.

Finally I added "echo "start SD"" to the function IMAGE_CMD_sdcard in
image_types_ls1.bbclass to see if the command is executed. But I ended up
with lots of red lines ...

I am sure that I do not understand the bitbake internals, but also I didn't
found any documentation. Do you have some hints?

Best regards
Thomas
