Hello,
I am working on an i.MX25 board, and would like to know the recommended
mechanism for putting code in before the first instruction in the
executable, but outside the *_spl system.
Basically, the i.MX25 has a smart boot rom in the CPU, which will
extract the first block, and interpret it (as

Yes, I am booting in internal mode, so that I can load U-Boot from NAND
(or SPI flash).
