Patch from John Cotton <john.cotton@…>, Charles-Antoine Gauthier
<charles.gauthier@…>, and Darlene A. Stewart
<Darlene.Stewart@…> to add support for a number of very
significant things:
+ BSPs for many variations on the Motorola MBX8xx board series
+ Cache Manager including initial support for m68040
and PowerPC
+ Rework of mpc8xx libcpu code so all mpc8xx CPUs now use
same code base.
+ Rework of eth_comm BSP to utiltize above.
John reports this works on the 821 and 860

| 5 | The location of the vectors file object is critical. |

| 7 | From the comments at the head of vectors.S: |
|---|
| 8 | |
|---|
| 9 | The issue with this file is getting it loaded at the right place. |
|---|
| 10 | The first vector MUST be at address 0x????0100. |
|---|
| 11 | How this is achieved is dependant on the tool chain. |
|---|
| 12 | |
|---|
| 13 | ... |
|---|
| 14 | |
|---|
| 15 | The variable 'PPC_VECTOR_FILE_BASE' must be defined to be the |
|---|
| 16 | offset from 0x????0000 to the first location in the file. This |
|---|
| 17 | will be either 0x0000 or 0xfff0. |
|---|
| 18 | |
|---|
| 19 | The eth_comm BSP defines PPC_VECTOR_FILE_BASE to be 0x00000000. |
|---|
| 20 | The MBX8xx BSP also defines PPC_VECTOR_FILE_BASE to be 0x00000000. |
|---|
| 21 | Change these values to 0xFFF00000 if your are implementing an actual |
|---|
| 22 | boot rom. |
