This is how I would approach it: 1) Look at the custom board's .dts file and make sure it has a crypto section with properties which match those in arch/powerpc/boot/dts/mpc8548cds.dts from 2.6.27.18. 2) talitos in 2.6.27.18 implements only ESP IPsec algorithms. So if you need h/w accelerated plain cipher or digest algorithms,there are not there. 3) If IPsec is what you are interested in using, talitos implements aes-cbc and 3des-cbc encryption, and hmac-sha1 & -sha256 & -md5 authentication. You can try it in 2.6.27.18. Turn on the necessary CRYPTO kernel options as well as applicable IPsec options. 4) For better IPsec performance, add the talitos patches made since 2.6.27 which are in the mainline kernel tree. (Linux 2.6.29-rc8 includes 7 extra patches). These could be added to 2.6.27.18 easily. Lee
