[U-Boot-Users] Add another FLASH to my board

I ordered a Strataflash from Intel (E28F128J3C), 128 Mbits.  I would like to
add it to the AT91RM9200 development board.

Is there any document to explain how to proceed to add a new flash memory?
So I will have two flashes to initialize.  But the first flash, it works.

The base address of the first flash (AT49BV162A - 2 MB) is 0x1000000

The base address of the strataflash memory : 0x30000000

To do?

1.  In lib_arm\board.c, I have to call a strataflash_init() routine in order
to initialize the flash_info_t structure.

2.  call display_flash_config to print out the flash size.

3.   I don't know what to do with these routines: flash_erase,  write_word,
write_buff.  The content of these routines are different if we access to the
strataflash or AT49 flash.  So, how can I manage it correctly?

Best regards
