[POWERPC] 4xx: Add AMCC 460EX/460GT support to cputable.c & cpu_setup_44x.S
This patch adds basic support for the AMCC 460EX/460GT PPC's to arch/powerpc. Currently those PPC's are still based on a 440 core and *not* a 460 core. Here some basic features of those SoC's: 460EX: - Up to 1.2GHz, 32kB L1 I-cache and D-cache, 256kB L2-cache, FPU - 1 * PCI (max 66MHz), 2 * PCIe (one 4-lane, one 1-lane) - 2 * GBit Ethernet with TCP/IP acceleration - USB 2.0 Host/Device OTG and Host interface - SATA controller - Optional security feature 460GT (only changes to 460EX): - 4 * GBit Ethernet with TCP/IP acceleration - RapidIO - No SATA - No USB Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
