Hi Aneesh,
BTW, I agree that enabling un-aligned access is not a bad idea.
Just being not a bad idea is not enough for me to accept this. It
will have to be the sole sound solution to a problem, and at this
point, I do not think it is as far as USB structure mis-alignement
issues are

What is the (non-contrived) problem to which allowing mis-aligned

memcpy() when there is a mismatch in the alignment of source and

Hi Lucas,
Linux in particular does reinitialize this state and I expect any
reasonable OS to do so.
Then what is the point of enabling it on U-Boot? Does it fix some
issue whereby some mis-aligned piece of data cannot be properly
aligned?
Yes, it fixes U-Boot USB on Tegra, when

Recent toolchains default to using the hardware feature for unaligned access on
ARM v7, rather than doing the software fallback. According to ARM this is safe
as all v7 implementations have to support this feature.
