  Hi,
 
  Are there plans to add crypto acceleration support to OMAP4? Has

  platform not supported:
 
  [0.370513] omap_init_sham: platform not supported
  [0.375488] omap_init_aes: platform not supported

 I recall hearing at some point that these are now available
 only in the secure mode? Maybe somebody from TI could
 check this?

Thats right. I will cross verify but at least for sure I know
that OMAP4 onwards, these blocks are not available for
non-secure software.
