Hi Baruch,
I provided the board/solid-run/hummingboard-i2eX/make_sd_card.sh script 
rather than use the board/freescale/create-boot-sd.sh script for the 
following reasons.

1. make_sd_card.sh supports OOT builds. Also support parameters in 
environment variables or command line.

2. make_sd_card.sh handles the likely multipath problem that happen in 
newer distros when you change partitions on media.

3. Moved the error control to the begining of the script so that there is 
less chance of leaving a mounted filesystem or temporary mount point if 
some requried file is missing and the -e kicks in.

4. Provides cumulative error control and check for many more types of 
error. That is, doesn't stop at the first error but continues noting all 
errors possible to detect before actually making any changes.

5. Copy only the specific images required rather than using wildcards that 
can result in the wrong images being copied and can leave the newbie 
wondering why the SD doesn't boot.

6. Having a separate script takes into account the fact that we are using 
forked U-Boot repo whose bootcmd might change from the bootcmd in the 
upstream repo.

The script that I provided in 
board/solid-run/hummingboard-i2eX/make_sd_card.sh
board/freescale/create-boot-sd.sh
