Hi Paul

I'm glad you like it, thanks.

I don't know much about the ipq8064 crypto engine, other than it is
not compatible with the ipq40xx one, and that's why I removed it from
the image.  I looked into it superficially, but couldn't find much
information about it.

What we can do right away is to enable the neon/arm-asm modules, as I
did for ipq40xx.  I'll wait for ipq40xx's fate, before I apply the
same logic to ipq806x, and perhaps others.  If I were to just grep for
CONFIG_NEON=y, but not CONFIG_ARM_CRYPTO=y:
$ git grep -L '^CONFIG_ARM_CRYPTO=y' -- $(git grep -l '^CONFIG_NEON=y'
-- target/linux/) | xargs -r dirname | sort -u
target/linux/armvirt/32
target/linux/at91
target/linux/bcm27xx/bcm2709
target/linux/ipq40xx
target/linux/ipq806x
target/linux/layerscape/armv7
target/linux/mediatek/mt7623
target/linux/omap
target/linux/samsung/s5pv210
target/linux/sunxi
target/linux/zynq

Cheers,

Eneas
