powerpc: mpc83xx: Minimize r1 modification The r1 register is modified several times during the cache-ram setup of the MPC83xx SoCs. Since this SP modification confuses debuggers, we use a general purpose register to compute the new stack pointer value, and only set the SP once after all computations are done.
