[U-Boot-Users] problems with the strataflash driver in U-boot

[Josh Fryman]

hi,

the strataflash driver (used in the U-boot boot loader project) is getting
confused by the configuration of flash i've got.  i'm CC'ing Brad Kemp, the
author of the driver, as i'm not sure he's a developer of U-boot.

the intel sitsang platform has the 28F128J3 (A150) on it.  it has 4 of these
16MB chips, set up to make a 32-bit wide flash interface.  the address lines
and flash bank enables are shared for both chips in a block.

ie:

   0-32MB:   high-data chip 1      low-data chip 0

  32-64MB:   high-data chip 3      low-data chip 2

should the driver support this?  it seems to be getting very confused right
in the beginnining of initialization, with flash_get_size() calling 
flash_isequal() which does this pattern of data xfer... (i've tossed in a lot
of debug statements :)

do i just have the permutation of CFG_foo flags set wrong?

thanks for any input,
