* crypto: omap-crypto - Verify page zone scatterlists before starting DMATero Kristo2018-03-091-0/+4
| | | | | | | | | | | In certain platforms like DRA7xx having memory > 2GB with LPAE enabled has a constraint that DMA can be done with the initial 2GB and marks it as ZONE_DMA. But openssl when used with cryptodev does not make sure that input buffer is DMA capable. So, adding a check to verify if the input buffer is capable of DMA.
