Hi Wolfgang,

Attached is a patch to allow the MPC8260FADS family of boards to be configured to boot either high (0xfff00000) or low (0x00000000). It was tested on a PQ2FADS-ZU (MPC8280 processor). I slipped in an unrelated change to the default load address and beg your indulgence in applying that as well.

Thanks, gvb

CHANGELOG:

* Patch by Jerry Van Baren 08 Nov 2004 - Enhance the PQ2FADS board (aka. mpc8260ads) to boot high or low based on whether "lowboot" is in the configuration target name. If lowboot is selected, the jumper for the HRCW source should select flash. If lowboot is not selected, the jumper for the HRCW source should select the BCSR.

The "boot low" configuration is highly recommended. With this configuration, the HRCW sets the IMMR to 0xf0000000 to be directly compatible with linux (the IMMR is properly positioned and does not need to be moved in start.S).

- The patch also changes the default load base address to 0x00400000 (was 0x00100000) to allow linux to boot properly.
