The Security function on the AMCC SoCs has multiple engines within a single MMIO range. The crypto driver currently enables the 3DES functionality by doing a blind write to the device control register. This can unintentionally disable other functions like the PKA or TRNG when the driver is loaded. Perform a read/modify/write to enable the 3DES function instead. Signed-off-by: Josh Boyer <redacted>
Patch applied. Thanks. -- Email: Herbert Xu [off-list ref] Home Page: http://gondor.apana.org.au/~herbert/ PGP Key: http://gondor.apana.org.au/~herbert/pubkey.txt
