thisseems not clean and seems caused by the fact that the define RCSR_MEM_CTL_SD should be 3 and not 2 so in your tests the function spl_boot_device was not detecting the right boot mode. Also IMHO this define should be named RCSR_MEM_CTL_EXPANSION as in the app note AN3996 at end of page 3 (there is a typo in the reference manual which seems to be a copy'n paste from i.MX25 as it doesn't take in acount the ATA HDD case) : http://cache.freescale.com/files/dsp/doc/app_note/AN3996.pdf
You're right, thanks ! I will fix in V2
