I have just tested top of tree U-boot and my mx53loco board boots fine.
That's because CONFIG_HAS_VBAR is set for ARMv7. There may be an issue, though: according to Freescale, the TrustZone security extensions are present on i.MX514/515/516/53x, but not on i.MX512/513. According to ARM, the security extensions seem to always be implemented on Cortex-A8, so it's not clear what Freescale means for i.MX512/513, and if the non-secure VBAR is still available on these. If not, 0x00000000 is the boot ROM, and 0xFFFF0000 is reserved, just like on i.MX25/27/31/35, so disabling CONFIG_HAS_VBAR for i.MX512/513 would not help, and your vector relocation patch would be required here too. It would be nice if someone could test the latest U-Boot on i.MX512/513.
Best regards, Benoît
