JSE Configuration Details
Memory Bank 0 -- Flash chip
---------------------------
0xfff00000 - 0xffffffff
The flash chip is really only 512Kbytes, but the high address bit of
the 1Meg region is ignored, so the flash is replicated through the
region. Thus, this is consistent with a flash base address 0xfff80000.
The placement at the end is to be consistent with reset behavior,
where the processor itself initially uses this bus to load the branch
vector and start running.
On-Chip Memory
--------------
0xf4000000 - 0xf4000fff
The 405GPr includes a 4K on-chip memory that can be placed however
software chooses. I choose to place the memory at this address, to
keep it out of the cachable areas.
Memory Bank 1 -- SystemACE Controller
-------------------------------------
0xf0000000 - 0xf00fffff
The SystemACE chip is along on peripheral bank CS#1. We don't need
much space, but 1Meg is the smallest we can configure the chip to
allocate. We need it far away from the flash region, because this
region is set to be non-cached.
Internal Peripherals
--------------------
0xef600300 - 0xef6008ff
These are scattered various peripherals internal to the PPC405GPr
chip.
SDRAM
-----
0x00000000 - 0x07ffffff (128 MBytes)

These are brief instructions on how to add support for CF adapters to
custom designed PXA boards. You need to set the parameters in the
config file. This should work for most implementations especially if you
follow the connections of the standard lubbock. Anyway just the block
marked memory configuration should be touched since the other parameters
are imposed by the PXA architecture.

do it please search for CONFIG_EXADRON1 in cmd_pcmcia.c
