Hi Simon,

Few question wrt sandbox flash driver - drivers/mtd/spi/sandbox.c

1. Does this driver used for creating flash emulation environment? or

something else?

It is an emulation driver, meant to emulate a SPI flash device. See sandbox_sf_emul_ops - the sandbox_sf_xfer() receives a SPI message from U-Boot and produces a reply.

2. Can't it use spi_flash.c core for all spi flash operations, how

different is this?

That is for talking to SPI flash devices I think, rather than emulating one.

Please let me know your inputs.

thanks!

Jagan.
