The L2 cache size is 512KB for 8568, print out the correct informaiton. Signed-off-by: Haiying Wang

85xxCDS: Add make targets for legacy systems.

2007-08-14T06:51:39Z

The PCI ID select values on the Arcadia main board differ depending on the version of the hardware. The standard configuration supports Rev 3.1. The legacy target supports Rev 2.x. Signed-off-by Randy Vinson

Empirically set cpo and clk_adjust for mpc85xx DDR2 support

2007-08-14T06:45:51Z

This patch is against u-boot-mpc85xx.git of www.denx.com Setting cpo to 0x9 for frequencies higher than 333MHz is verified on both MPC8548CDS board and MPC8568MDS board, especially for supporting 533MHz DDR2. Setting clk_adjust to 0x6(3/4 late cycle) for MPC8568MDS board is for DDR2 on all current board versions especially ver 1.92 or later to bring up. Signed-off-by: Haiying Wang

Use an absolute address when jumping out of 4k boot page

2007-08-14T06:45:09Z

On e500 when we leave the 4k boot page we should use an absolute address since we don't know where the board code may want us to be really running at. Signed-off-by: Kumar Gala

MPC85xx BA bits not set for 3-bit bank address DIMM

2007-08-14T06:44:55Z

The current implementation does not set the number of bank address bits (BA) in the processor. The default assumes 2 logical bank bits. This works fine for a DIMM that uses devices with 4 internal banks (SPD byte17 = 0x4) but needs to be set appropriately for a DIMM that uses devices with 8 internal banks (SPD byte17 = 0x8).

Fix minor 85xx warnings

2007-08-14T06:39:14Z

Some patches had inserted warnings into the build: * mpc8560ads declared data without using it * cpu_init declared ecm and immap without using it in all CONFIGs * MPC8548CDS.h had its default filenames changed so that they contained "\m" in the paths. Made the defaults not Windows-specific (or anything-specific) Signed-off-by: Andy Fleming

85xx start.S cleanup and exception support

2007-08-14T06:34:21Z

From: Ed Swarthout Support external interrupts from platform to eliminate system hangs. Define CONFIG_INTERRUPTS board configure option to enable. Enable ecm, ddr, lbc, and pci/pcie error interrupts in PIC. Remove extra cpu initialization redundant with hardware initialization. Whitespace cleanup. Define and use _START_OFFSET consistent with other processors using ppc_asm.tmpl Move additional code from .text to boot page to make room for exception vectors at start of image. Handle Machine Check, External and Critical exceptions. Fix e500 machine check error determination in traps.c TEXT_BASE can now be 0xfffc_0000 - which cuts binary image in half.
