052ef6dc5a Added nvs_write(). This shares a lot of code in common with nvs_read();
this can probably be optimised down quite a lot.

946967f09c Abstracted out part of the concept of an SPI device to a generalised NVS
device.

Separated the mechanisms of non-volatile storage access and non-volatile
stored options.

dc06c895fc Changed length parameter in SPI methods to be a byte length, rather than
a word length.

931f94dca3 Generalised the SPI abstraction layer to also be able to handle interfaces
that don't provide the full flexibility of a bit-bashing interface.

Temporarily hacked rtl8139.c to use the new interface.

3b51c719d3 Generalise three-wire interface to generic SPI interface.
Update rtl8139 driver to instantiate an SPI interface with a three-wire
device attached.

aa2468babe Added abstraction layer for a three-wire serial device (e.g. the EEPROM
used on RTL8139 cards).
