What makes you sure barebox stops there? Do you have DEBUG_LL enabled or
do you use a JTAG debugger?

Does this happen in first stage boot only or also when you chainload
barebox from an already running barebox?

You could try calling imx53_init_lowlevel_early from
barebox_arm_reset_vector(). This *could* make a difference.

Since you are using v2013.05-stable you should have the following
patches, but maybe it's worth rechecking.

76820df ARM: invalidate data caches during early init
f9d7582 ARM v7: added v7_mmu_cache_invalidate()
ee5f859 ARM v7: v7_mmu_cache_flush(): do not restore r0-r3 (minor optimization)
eb7d85c arm: properly init alignment trap bit
7904d90 ARM v7: fix mmu-off operation
9af1150 ARM: fix the memset fix
