Hardware support for Cryptography operations

Hi All,

I'm working over DM8148 EVM with EZSDK_5.5 version. We have requirement of decrypting contents by using AES (Advanced encryption standard). I was following 'http://processors.wiki.ti.com/index.php/Installing_AM387x_C6A814x_DM814x_Crypto_Support' link to enable cryptographic acceleration to boost performance, but I did not get following two options in menuconfig file under 'Hardware Random Number Generator Core'' while building kernel object:

<*> Hardware Random Number Generator Core support
  <*>   Netra Random Number Generator support (NEW)

Also I did not find following options :
--- Hardware crypto devices
  < >   Driver HIFN 795x crypto accelerator chips (NEW)
  <*>   Support for Netra AES hw engine (NEW)
  <*>   Support for Netra DES hw engine (NEW)
  <*>   Support for Netra SHA/MD5 hw engine (NEW)


1. Does DM8148 board provides any sort of acceleration for Cryptographic functions (viz. Decryption) ?
2. If DM8148 does provide support, How to enable above mentioned options while building modules for these accelerators ?

Thanks in advance.

    Hi All,

    The patch 'NSS-Crypto-driver-software-beta-0.9.patch' mentioned in link is not proper. I found the correct patch while going through http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/209641.aspx.

    Now I got all the above mentioned options and have started the kernel compilation for cryptographic support.

    Thanks,
