H A D | omap-aes.c | f9fb69e7 Tue Jan 08 12:57:47 CST 2013 Mark A. Greer <mgreer@animalcreek.com> crypto: omap-aes - Add CTR algorithm Support
The OMAP3 and OMAP4/AM33xx versions of the AES crypto module support the CTR algorithm in addition to ECB and CBC that the OMAP2 version of the module supports.
So, OMAP2 and OMAP3 share a common register set but OMAP3 supports CTR while OMAP2 doesn't. OMAP4/AM33XX uses a different register set from OMAP2/OMAP3 and also supports CTR.
To add this support, use the platform_data introduced in an ealier commit to hold the list of algorithms supported by the current module. The probe routine will use that list to register the correct algorithms.
Note: The code being integrated is from the TI AM33xx SDK and was written by Greg Turner <gkmturner@gmail.com> and Herman Schuurman (current email unknown) while at TI.
