[U-Boot] support for spansion s29gl-p flash?

Hi Stefan,

> OK. So you are using 2 chips interleaved on this 16bit bus (one on lower 8bits 
> and one on higher 8bits), right?
  No, I misunderstood yor last e-mail. 	Our layout is:
	The flash chip is 16x/8x capable but is configured in 8x mode ( _BYTE
pin to GND). 
	Only the low 8 data bits from the processor are connected to the flash
data bits. 
	So, I think our layout is chip_width = 8 and port_width = 8. Is it
correct?

This is the flinfo report from U-Boot. It's from a Spansion flash board
but the Numonyx flash board has the same layout.

Bank # 1: CFI conformant FLASH (8 x 8)  Size: 16 MB in 128 Sectors
  AMD Standard command set, Manufacturer ID: 0x01, Device ID: 0x7E2101
  Erase timeout: 4096 ms, write timeout: 1 ms
  Buffer write timeout: 3 ms, buffer size: 64 bytes



NOTE: I think the layout you point out could be supported by U-Boot.

We are working with a 2.4.25 kernel version and the Numonyx is not fully
supported (our layout I'm quite sure not). We did some changes to fix
it, if you are interested in it I could submit you a patch.
