the AT45DB321D is supposed to be 64 block per sector and 64 sectors

[U-Boot] [PATCH] spi/atmel: add AT45DB321D support

[Brad Bozarth]

Hmm... looking in the datasheet I have, it says:
Flexible Erase Options
? Page Erase (512 Bytes)
? Block Erase (4 Kbytes)
? Sector Erase (64 Kbytes)
? Chip Erase (32 Mbits)

which would indicate a third combo, different from mine and yours :)
--- 16 blocks/sector and 64 sectors... The code only does page based
so far, so I didn't catch this.

The dataflash is normally 528/1056 bytes per page.
D versions can be configured to have a 512/1024 bytes per page
but that is wasting a couple of percent of the dataflash.

Blackfins can only boot with power of two flashes, so power of two page mode 
has to be supported for us ... not sure if the latest drivers have been fixed 
yet (both in u-boot and Linux)

[U-Boot] [PATCH] spi/atmel: add AT45DB321D support

[Brad Bozarth]

Linux - yes, it's supported. Uboot - I have another patch that allows  
power of 2 mode (I believe it's on the blackfin portal).

istr said patch was against the Blackfin eeprom/spi driver and not the new 
common layer ?  ive been largely ignoring changes to that driver and focusing 
on adding support for spi flashes to the new subsystem (spansion/sst/etc...).

whatever happened to this patch ?  it isnt in mainline, i dont know of a "mtd" 
or "spi" git tree, and it should apply cleanly still ...

it shouldnt cause any regressions considering the existing atmel driver has 
all of 1 id in it today

Normally it's still apply but it's still not in mainline
