-- Hi all,
I am new to this list, I planned port u-boot on my board(pxa255),

Hi all,
I tried to debug why it is stopping after
DRAM Configuration:
Bank #0: a0000000 64 MB
Bank #1: a4000000 0 kB
Bank #2: a8000000 0 kB
Bank #3: ac000000 0 kB
It is unable to find the flash type;
and control is not coming out of flash_init() function.
Regards,
Naveen.

Hi,
As far as I know CFG_MAX_FLASH_BANKS should be set to 1 always.
Multiple flash banks in u-boot are not supported.
> Flash: 0 kB
This message is saying that u-boot was unable to detect the flash chip
itself.
The easiest way to get you flash working:
1. add flash id in include/flash.h (check your flash datasheet)
2. based on board/../flash.c get it working (probably you will need only
sector organization, also a datasheet material)
Hope this helps.
Regards,
Andrejs Cainikovs.

I have a system with two banks.

As expected, it also works in the older board with one bank only (no
CFI QRY found for second bank and everything continues as smooth as always).

Huh!? Well, there is some time since we have implemented the flash
support for our board (Atmel AT91RM9200 based),
but at the moment we have done that, as far as I remember it was
impossible to support both chips we have.

Our boards flash driver is the same as in board/atmel/at91rm9200dk/flash.c
The only thing that was modified is the flash identification routine, as
there was no support for AT49BV642D.
The flash organization for this chip is the same as in AT49BV6416 which
exists in the sources, so we haven't changed a lot.
So, I think that's all are board dependent what and where are easier
and/or faster to implement.

I can understand this position to some extend from your local,
project-specific point of view. But in general, and especially from
the point of view a maintainer of the whole U-Boot project, I
strongly discourage the use of custom flash drivers if you could use
the CFI driver as well.
So please do not recommend to use custom drivers in new projects (and
don't do it your self either), because such code will not be accepted
for inclusion into mainline.

Pardon...
Now i'm wonder how easy CFI driver can be implemented on AT91 and why
somebody haven't done this already.
I think now I'll get my hands on that.
Kind regards,
Andrejs Cainikovs.

This chip is supported by the CFI driver (the ATNGW100 board relies on
that.)

This chip is not yet supported by the CFI driver. It needs a fixup due
to reversed erase region information, but since the CFI driver only
reads the low 8 bits of the ID, there's currently no way to tell it
apart from AT49BV642D, which doesn't need this fixup.
If someone can figure out how to read a 16-bit ID when appropriate, I
suspect we can get rid of quite a few board-specific flash drivers
(including the one for ATSTK1000).
Unfortunately, I don't have the time to look into this myself at the
moment.

Hi all,
The flash chip in my board is Intel 28F256P33T
which is not defined in the u-boot-1.1.6/include/flash.h
Please guide what is the procedure i should follow to add it.
