Hello Simon,
The Aspeed AST2500 FMC controller can handle SPI flash and NOR flash memory, and the Aspeed AST2500 SPI Flash Controllers only SPI. If there is some misunderstanding on this driver, it might come from the fact it is closer to a SPI-NOR driver like we have in Linux, than a generic SPI driver. The stm32 SPI driver is somewhat similar.
Should we move it under drivers/mtd/spi/ maybe ?
Seems with new spi-mem in Linux flash memory driver rely on spi-mem instead of mtd/spi-nor. So I think you can handle this via new spi-mem. have you send any patches to Linux?
No, not yet. The patchset is sent :
https://patchwork.ozlabs.org/cover/933293/
is not using spimem. I was not aware of that change in the spi-nor layer at the time. I will take a look.
Is there a similar framework in u-boot ?
Thanks,
