Good morning!
What version of the AT91SAM9260EK u-boot code are you referring to?
I am using u-boot-1.1.5_atmel_1.2 from the Atmel ftp site. Is there a more recent version available? Are there any plans to add the at91sam9260ek support to the main branch of u-boot (latest version 1.2).
The Atmel U-Boot for the AT91SAM9260/1/3 chips uses a common driver for dataflash. This is located in the "drivers/at45.c" If the Atmel U-boot patches are installed, it will break the "board/at91rm9200dk" and "board/cmc_pu2" since it duplicates the functionality. Additional boards coming from Atmel will use the same dataflash driver. The "board/at91rm9200dk/at45.c" functionality is split into a CPU dependent part located in "cpu/arm926ejs/at91sam926x/spi.c" and the "board/at45.c" file.
I tried to start the process of merging with mainstream U-boot by sending in a patch which split the at45.c located in board/at91rm9200dk into * drivers/at45.c * cpu/arm920t/at91rm9200/spi.c but I have no feedback.
Peter Pearse which will be responsible for maintaining the ARM part is not up to speed yet, and noone else seems to be interested.
There has been a discussion about how dataflash should be supported but the things people do not like are not in this file, they are in the "board/dataflash.c" file so I have no clue why nothing is happening.
