I am a bit confused about the use of the driver model when it comes to spi flash.
It seems from the description in the Kconfig help that both the legacy and dm interfaces for spi flash can coexist, thus you can use both the "sf xxxx" commands as well as use the driver model interface for the likes of flash..
is that correct? or is it one or the other?
2ndly, I've been trying to build u-boot for an TI am335x_evm (well our board is designed largely the same as that) attached to the spi flash is is25lp512 nor flash. when I try to configure both the CONFIG_SPI_FLASH and the CONFIG_DM_SPI + CONFIG_DM_SPI_FLASH i get lots of build errors.
I have a version of u-boot from 2017-09, I'll update to the newer version next but just wondering if anyone has done this and knows which config options to set/not set
thanks mike
