Hi,
Are there plans to add crypto acceleration support to OMAP4? Has
this hardware component been removed from OMAP4? I tried to load the
code written for OMAP3 on my Pandaboard, but it just outputs
"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.
