OpenSSL MIPS32R2 optimization


for a case study I optimized the openssl AES de-/encryption assembler routines for MIPS32R2. Upstream patch is pending at IIRC these will be used in OpenVPN builds too. Maybe someone can give give it a try and report back if he sees any benefits.

Best regards.

I'm scheduling the tonight build with your pr, so by tomorrow night I might have that flashed and we'll see how it rolls.

Thank you for your efforts.
