Do you think we could use spi-nor for Broadcom's SPI Atmel flashes? If
so, we could need this.

Broadcom's code includes support for two Atmel flashes: AT25F512 and AT25F2048.

>From what I can see, Atmel-specific code uses command 0xD7 (checking

flashes using command 0xD7 (checking for bit 0x80 to be unset).
