Okay success on another bisect run to find what was causing the Data
Abort with linaro's gcc toolchain..
gcc version 4.7.3 20121205 (prerelease) (crosstool-NG
linaro-1.13.1-4.7-2012.12-20121214 - Linaro GCC 2012.12)

Reverting, Troy's last 4 imximage changes:

ab857f2613be39274d0870768720067ff9d859c0 (imximage: make
set_imx_hdr_v1/v2 easier to read)
ad0826dcd81ba6cf4cc93a4ca8337e1bc676c238 (imximage: change parameters
to set_imx_hdr)
243319825fa6e79885d57b6b78e72f3fe10ef69c (imximage: delay setting of image size)
348ca8efb79652d2b259fbd0ed6d317a77a8cbb9 (imximage: fix size of image
to load.) (this was the first bad bisect, the previous 3 are needed
for a clean revert)

Along with Fabio's "mx53loco: Call PMIC related functions from
board_late_init()"

The Dialog based mx53loco is no operating correctly with linaro's toolchain...
