* Use an absolute address when jumping out of 4k boot pageKumar Gala2007-08-14-29/+24
| | | | | | | 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 <galak@kernel.crashing.org>
* 85xx start.S cleanup and exception supportAndy Fleming2007-08-14-278/+207
| | | | | | | | | | | | | | | | | | | | | | | | | | From: Ed Swarthout <Ed.Swarthout@freescale.com> 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.

* [ppc] Fix build breakage for all non-4xx PowerPC variants.Rafal Jaworowski2007-06-22-2/+2
| | | | | - adapt to the more generic EXCEPTION_PROLOG and CRIT_EXCEPTION macros - minor 4xx cleanup
* u-boot: v2: Remove the fixed TLB and LAW entrynubmerZang Roy-r619112007-04-23-12/+4
| | | | | | | | | Remove the fixed TLB and LAW entry nubmer. Use actually TLB and LAW entry number to control the loop. This can reduce the potential risk for the 85xx processor increasing its TLB adn LAW entry number.
