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. -- Best Regards, Ulf Samuelsson ulf at atmel.com Atmel Nordic AB Mail: Box 2033, 174 02 Sundbyberg, Sweden Visit: Kavalleriv?gen 24, 174 58 Sundbyberg, Sweden Phone +46 (8) 441 54 22 Fax +46 (8) 441 54 29 GSM +46 (706) 22 44 57 Technical support when I am not available: AT90 AVR Applications Group: mailto:avr at atmel.com AT91 ARM Applications Group: mailto:at91support at atmel.com links: www.avrfreaks.net; www.at91.com; avr32linux.org -------------- next part -------------- A non-text attachment was scrubbed...
