Charlie Jenkins	4525462dd0	riscv: lib: Check if output in asm goto supported ... The output field of an asm goto statement is not supported by all compilers. If it is not supported, fallback to the non-optimized code.

Charlie Jenkins	a04c192eab	riscv: Add checksum library ... Provide a 32 and 64 bit version of do_csum. When compiled for 32-bit will load from the buffer in groups of 32 bits, and when compiled for 64-bit will load in groups of 64 bits. Additionally provide riscv optimized implementation of csum_ipv6_magic.
