* Tero Kristo [off-list ref] [160314 02:02]:
EDMA was allocating DMA channels 32 and 33 for memcpy usage, out of which channel 33 is actually used by DES crypto engine. This bad allocation of the channel causes a crash in the DES crypto engine, as the channel gets configured for memcpy usage instead of hardware <-> memory DMA. Fixed by allocating DMA channels 58 and 59 for memcpy usage (I2C0 RX/TX), which are not used by anybody.
Thanks applying into omap-for-v4.6/fixes with Cc stable v4.4+. Tony
