6163045bcd sf: unify status polling for ready bit
All of the spi flash drivers implement the status register polling for
detecting the device ready state, so unify them all in a new helper
function -- spi_flash_wait_ready.

b376bbb49f sf: move useful messages from debug to printf
At the moment, the default SPI flash subsystem is quite terse.  Errors and
successes both result in a generic message.  So move the useful errors and
useful successes to printf output by default.

While we're here, also convert the messages to use print_size().

68f8718df2 spi flash: fix crash due to spi flash miscommunication
Higher spi flash layers expect to be given back a pointer that was
malloced so that it can free the result, but the lower layers return
a pointer that is in the middle of the malloced memory. Reorder the
members of the lower spi structures so that things work out.

d25ce7d24c SPI Flash subsystem
This adds a new SPI flash subsystem.

Currently, only AT45 DataFlash in non-power-of-two mode is supported,
but some preliminary support for other flash types is in place as
well.
