powerpc/85xx: Add support for Freescale P1023/P1017 Processors
Add P1023 (dual core) & P1017 (single core) specific information: * SERDES Table * Added P1023/P1017 to cpu_type_list and SVR list (fixed issue with P1013 not being sorted correctly). * Added P1023/P1027 to config_mpc85xx.h * Added new LAW type introduced on P1023/P1017 * Updated a few immap register/defines unique to P1023/P1017 Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
