This is exactly the way we use to prepend an header for the i.MX
processors that it is automatically executed before start.S. The i.MX25
uses V1 version of the imximage, as the MX35 and MX51. However, there is
not yet MX25 boards in u-boot using this mechanism.
Of course, it works if (as it should be) the code you want to add has
the goal to write defined values and you cannot add any type of logic.
The syntax is very simple and accepts the format
<data wide> <address you want to write> <value>.
You can check the imximage file for mx51/mx53 boards and as reference
the doc/README.imximage, as already stated by Fabio.
Best regards,
Stefano Babic
