Harald: This patch should fix your problems writing to the chip. Use either "patch -l" or remove the // before //while (generic_spi_read_status_register() & JEDEC_RDSR_BIT_WIP)
Ronald: I need an ack to commit this.

Did you have time to test with the while (generic_spi_read_status_register() & .._WIP) enabled? It would be more correct to have it enabled.
I had that in initially (that's why it was there, but commented out) but all it got me was slower programming times and the datasheet also suggests it is ok to just do a timed wait. But in the face of genericness for other chips, it is indeed more correct to do the check for the busy bit.
Ronald/Harald, can you please ack the change? It is reproduced below (whichspace-damaged).

Make sure we delay writing the next byte long enough in SPI byte programming. Minor formatting changes.
