I don't understand why this is needed. It seems like something more fundamental in the u-boot allocator if it can't handle all the devices in 1M of memory space. No devices memory space requirement is greater than 4k and there are only 5 or 6 of them.
This 'hack' seems to workaround the issue in slightly better way. Not sure if we can do anything better.
The problem is pciauto_setup_device() getting called from fsl_pci_init.c is allocating memory space it doesn't need.
