The issue I've had with CCSR relocation has been fixed by Timur's patchset titled "powerpc/85xx: fix definition of MAS register macros". So you don't really need to test this. If you'd like to test it anyway, use P2020DS_SDCARD, where you use the boot_format tool + configuration file to write the U-Boot image to the SD card. It should be booting with the help of the Freescale On-Chip ROM.
