The malloc() calls are unnecessary, just allocate the stuff on stack.
While at it, reorder the code a little, so that only one variable is
used for the text, use snprintf() instead of sprintf() and use %01d
as a formatting string to avoid any possible overflows.

This board uses setup_i2c() in SPL. The setup_i2c() function internally
calls gpio_request(), which in turn internally calls strdup(). The strdup()
requires a running mallocator, so this patch makes the mallocator available.

Sequence like the following is completely useless and results from
an errorneous ordering of the statements during development. Zap it.

Pull the definitions of GPIOs into a separate header file, so that
they can be used across all source files.

Pull all of the video handling into a separate file, since a lot
more code will be added and such code would polute the board file.

Could perhaps move the board to driver model for I2C.

Does this board use driver model? If not it should be easy to convert
since one MX6 board supports it. With driver model there is
gpio_requestf("i2c_sda%01d", i2c_index);

That's the plan, not only this one, but SoCFPGA in general and all the DENX
boards.

No, not yet, but it's in the pipeline. I am already keeping an eye on a few
conversion patches to get this done.

Hey!
hope you had a nice holiday :) You might want to apply 2/8 and 3/8 to current

Best regards,
Marek Vasut
