how to adress flash memory in Linux

[Ming Liu]

Dear Peter,
Here is the booting information about my cfi flash. Maybe it's useful for 
you to help on my questions. :-)

eth%d: XTemac using sgDMA mode.
eth%d: XTemac buffer_descriptor_space: phy: 0x3c90000, virt: 0xff100000, 
size: 0x5000
eth0: Xilinx TEMAC #0 at 0x81200000 mapped to 0xC4000000, irq=0
physmap flash device: 800000 at 22000000
phys_mapped_flash: Found 2 x16 devices at 0x0 in 32-bit bank
 Intel/Sharp Extended Query Table at 0x0031
Using buffer write method
cfi_cmdset_0001: Erase suspend on write enabled
Searching for RedBoot partition table in phys_mapped_flash at offset 
0x7c0000
No RedBoot partition table detected in phys_mapped_flash
NAND device: Manufacturer ID: 0x98, Chip ID: 0x39 (Toshiba NAND 8MiB 1,8V 
8-bit)
flash size: 8 MiB
page size: 512 bytes
OOB area size: 16 bytes
sector size: 8 KiB
pages number: 16384
pages per sector: 16
bus width: 8
bits in sector size: 13
bits in page size: 9
bits in OOB size: 4
flash size with OOB: 8448 KiB
page address bytes: 3
sector address bytes: 2
options: 0x62
Scanning device for bad blocks
Creating 1 MTD partitions on "NAND 8MiB 1,8V 8-bit":
0x00000000-0x00800000 : "NAND simulator partition"
mice: PS/2 mouse device common for all mice
NET: Registered protocol family 2

Here it says "Creating 1 MTD partitions on "NAND 8MiB 1,8V 8-bit":". So it 
looks like that I have not yet provided my own partition information. So 
what shall I do?..... Thank you for helping.

Regards
Ming
