Version 6.00 of the TI Sitara SDK supports(*) the BBB:

It allows you to cross compile the TI kernel. Note that you need a serial
connection to access the console (an FTDI cable probably is the best
choice). I couldn't get the network based boot to work,
Ok, so with 3.13.0-rc6-bone2.8 and
CONFIG_USB_TI_CPPI41_DMA=y
# CONFIG_MUSB_PIO_ONLY is not set
I'm getting about 14MB/s which is much better than before but still less
than with the TI v3.2 Kernel.

Great, that sounds promising :-)
Unfortunately, with 3.13.0-rc3 USB currently does not seem to work at all
(also no ethernet).

Apparently, it's unrealistic to expect good performance from dm-crypt with
HW acceleration, given that it uses a block size of 512 bytes:

Ok, first of all, the transfer speeds obtained with hdparm with the saucy
image seem to be unrealistic, because cross checks with dd on files again
show much lower speeds (maybe some compiler optimization at work here?).
Secondly, I now have a pointer why HW acceleration is not working: There
I'm trying to use the HW AES acceleration on BBB with dm-crypt.
So far my results have been mixed (see also

While it didn't work at all on 3.8 kernels, with 3.12 kernels there were no
errors, but I could not find any indications that dm-crypt
Well, I've checked out the official TI Kernel v3.2 and now I get speeds
well beyond 20MB/s. Does anyone have a clue why the newer Kernels are so
much worse?

I'm trying to use the BBB as a (very) lightweight NAS. Unfortunately, I'm a
bit disappointed with the transfer speed I can achieve over the USB port.
I've now tried different kernels such as Robert C Nelsons 3.8.13-bone28 and
3.12.0-rc5-bone6, different USB storage devices (such as a USB 2.0
