hwmod file for OMAP 4460 with aes definition

Hi

From SDK6 for AM335x, I can see that the AES hwmod layer is defined in omap_hwmod_33xx_data.c file.

Where can I get the similar hwmod layer definition for OMAP4460's AES ? Kindly point me to a kernel source that has it.

    Hello,

    There is no such information for AES in OMAP devices. They come with already set security/crypto engines. All you can do with the crypto modules is modify their clock settings from PRCM module. Available crypto files are located in:

    <linux kernel sources folder>/drivers/crypto and <linux kernel sources>/crypto for linux

    <adroid_sources>/kernel/android-3.4/crypto and <adroid_sources>/kernel/android-3.4/drivers/crypto for Android

    Best Regards,

    Yordan

    Yordan,

    Thank you very much for your clarification.

    I am trying to get AES HW module working on OMAP4460 . I found kernel sources for OMAP4 at http://www.omappedia.com/wiki/Ubuntu_kernel_for_OMAP4#Ubuntu_kernel_sources

    In them, AES on OMAP4460 is not being used. The available code is a generic driver. But from reading AES Crypto Addendum for OMAP4460, I found that the crypto/driver/omap4-aes.c from AM335x's SDk v6 can be used as is.

    What I couldn't find is the OMAP4460 specific hwmod layer details at arch/arm/mach-omap2/omap_hwmod_44xx_data.c . Can you point to a kernel for OMAP4460 where those details are available?

    Thanks.
