Re: [U-Boot] [PATCH 4/6] riscv: replace use of callee-saved register in standalone

Register x19 (s3) is a callee-saved register. It must not be used to load and jump to exported functions without saving it beforehand. Replace it with t0, a temporary and caller-saved register.

Change the code comment to reflect this and fix it to correctly list gp as the register with the pointer to global data.
