Is not possible to change the behavior of the script filtering the
$blobs variable before evaluating ? The check is just for skipping these
two files.

Something like :

 blobs=`awk '/^SIGNED_HDMI/ {print $2} /^LOADER/ {print $2}
/^SECOND_LOADER/ {print $2} /^DDR_FW/ {print $2}' $file` | grep -v
""spl/u-boot-spl-ddr.bin" | ......

It look to me better to put in $blobs just the values that must be
evaluated instead of checking them later. $blobs is not evaluated anymore.

Best regards,
Stefano
