This patch removes all self references and fixes references to files in the now defunct arch/ppc64 tree. I think this accomplises everything wanted, though there might be a few references I missed. Signed-off-by: Jon Mason <jdmason@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

* The MV64x60 has 2 PCI buses each with 1 window from the CPU bus to

* PCI I/O space and 4 windows from the CPU bus to PCI MEM space.
|
|
* We'll only use one PCI MEM window on each PCI bus.
|
|
*
|
|
* This is the CPU physical memory map (windows must be at least 1MB and start
|
|
* on a boundary that is a multiple of the window size):

|
* 0xfc000000-0xffffffff - External FLASH on device module
|
|
* 0xfbf00000-0xfbffffff - Embedded (on board) FLASH
|
|
* 0xfbe00000-0xfbefffff - GT64260 Registers (preferably)
|
|
* but really a config option
|
|
* 0xfbd00000-0xfbdfffff - External SRAM on device module
|
|
* 0xfbc00000-0xfbcfffff - TODC chip on device module
|
|
* 0xfbb00000-0xfbbfffff - External UART on device module
|
|
* 0xa2000000-0xfbafffff - <hole>
|
|
* 0xa1000000-0xa1ffffff - PCI 1 I/O (defined in gt64260.h)
