Question about SPI NOR flash

[Holger Schurig]

Hmm, this patch waits for both RDSR bitmask 0x01 not set AND for RDFSR
bitmask 0x80 set. I looked at u-boot, which does either one or the
other, depending on an E_FSR flag in the probe data.

However, still no joice (althought a printk revealed that the FSR
ready bit was set).

The NOR flash is actually a dual-die chip, so I'm now looking into
u-boot's CONFIG_SF_DUAL_FLASH code ...
