Do you really need to enable all clocks ? Most boards try to enable just
the clocks they nee, not all.
There is a problem with this file. This seems coming from a very old
port, and it does not follow semantic as other imximage.cfg files.
You post a ddr2.cfg file and you see the differences: instead of bare
hexadecimal values for register address, the register name is used,
because the preprocessor runs before calling mkimage.

If you switch to SPL, all this stuff is managed by common code.
Even if you do not want it, you should factorize this in several files,
maybe reusing some .fg from other boards. Take a look at
boudary/nitrogen6x (nitrogen6q.cfg).
And register address must be substituted by names, as you have already
done for the second file.

We had this status at the beginning with i.MX6 - it is pity if a board
will be introduced dropping all common code.
This RAM chip is used on several i.MX6 board, and configuration can be
reused.

Most of this file is currently replaced by common code. And if you use
