Since commit ff98cb90514d ("part: extract MBR signature from partitions") SPL boot on i.MX6 starts to fail:
U-Boot SPL 2017.09-00221-g0d6ab32 (Oct 02 2017 - 15:13:19) Trying to boot from MMC1 (keep in loop)
Use the original allocation scheme for the SPL case, so that MX6 boards can boot again.
This is a temporary solution to avoid the boot regression.

Hi Tom,
I do not have time this week to further investigate and narrow down this problem.
Using the old allocation scheme fixes the mx6 SPL boot problem.
Hi Tom, if you are ok with this as a temporary fix, then this is:

I'm getting some help from some of the fedora-arm folks so hopefully I can get some idea what is going wrong, but I'd like to unblock folks w/ mx6 boards..

This does not seem to be a complete fix, cubox is still broken when U-Boot proper loads, unless the efi loader commits are to blame for introducing unaligned accesses.
Works with 2017.09.

I don't think any efi_loader code is running here, you would see a message like:
## Starting EFI application at XYZ
But to be sure you can disable CONFIG_EFI_LOADER in menuconfig to confirm.
I guess this is some unrelated change. I suspect Tom's change to malloc the fat_itr's which would make the buffers used for fs_exists()/etc not cache aligned. I thought there was a patch floating around to change that to memalign().
