Sorry, just stumbled over this message now.
We discussed exactly this issue already more than a year ago, see:
http://lists.denx.de/pipermail/u-boot/2014-April/177580.html
Back then you asked whether I asked Freescale about it. Earlier this
year I tried to get hold of that issue and asked Freescale on Community,
see:
https://community.freescale.com/thread/355161
However, no official confirmation or explanation so far.
I think my patch back then solves the issue nicer. The struct dcd_v2_t
is not the reason the whole header is not aligned by 8-byte, it is a
problem of the boot_data_t header which is 12 bytes long. So inserting
the padding just after struct boot_data_t (or inside of struct
boot_data_t) seems to be more appropriate.
