Hello Alvaro,

commit: 6c94bd12c4ad "drivers: spi: consider command bytes when sending transfers"

breaks for me on a ls1021a based board write support for SPI NOR.

After removing this commit, writting SPI NOR works fine.

Board is not yet mainlined, as I work on the U-Boot port currently, but
it is similiar to "ls1021a-iot" board. SPI NOR flash is the same, see

http://git.denx.de/?p=u-boot.git;a=blob;f=arch/arm/dts/ls1021a-iot.dtsi;h=1817c62c04c5fe728c4de34d00476f4cbe356003;hb=275d80a4c2fb63890f3f4c16b7ad481064e650a0#l28

I wonder if SPI NOR is working on the ls1021a-iot board.

@Feng Li: Can you check with current mainline, if writting SPI NOR
           works for you ?

Any ideas?

Thanks!

bye,
Heiko
