Michael Brown	92a9978b44	[spi] Add address-length autodetection to the SPI bit-bashing code Several SPI chips will respond to an SPI read command with a dummy zero bit immediately prior to the first real data bit. This can be used to autodetect the address length, provided that the command length and data length are already known, and that the MISO data line is tied high.

Michael Brown	052ef6dc5a	Added nvs_write(). This shares a lot of code in common with nvs_read(); this can probably be optimised down quite a lot.	18 jaren geleden

Michael Brown	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.	18 jaren geleden
Michael Brown	dc06c895fc	Changed length parameter in SPI methods to be a byte length, rather than a word length.	18 jaren geleden
Michael Brown	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.	18 jaren geleden
Michael Brown	3b51c719d3	Generalise three-wire interface to generic SPI interface. Update rtl8139 driver to instantiate an SPI interface with a three-wire device attached.	18 jaren geleden
Michael Brown	aa2468babe	Added abstraction layer for a three-wire serial device (e.g. the EEPROM used on RTL8139 cards).	18 jaren geleden
