Michael Brown	95cb7aaacf	Support cards such as natsemi which treat the data as little-endian (i.e. LSB transmitted first on the wire), even though SPI commands and addresses always have to be big-endian.	17 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.	17 jaren geleden
Michael Brown	dc06c895fc	Changed length parameter in SPI methods to be a byte length, rather than a word length.	17 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.	17 jaren geleden
Michael Brown	88e38fa148	We don't actually have a stdio.h header file. Our printf() functions are defined in vsprintf.h. (This may change, since vsprintf.h is a non-standard name, but for now it's the one to use.) There should be no need to include vsprintf.h just for DBG() statements, since include/compiler.h forces it in for a debug build anyway.	18 jaren geleden
Marty Connor	6ac78f6aff	added stdio.h to includes for DBG compilation	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	ab4f96e525	Move per-transition delays from generic bit-bashing layer to i2c layer (since SPI bit-bashing will require different delay semantics).	18 jaren geleden
Michael Brown	51a36f1cfb	Change read_bit() to return 0 or -1UL, rather than 0 or 1.	18 jaren geleden
Michael Brown	3ed40686c9	Added bit-bashing i2c interface code	18 jaren geleden
Michael Brown	e90b64d625	Added sketch of bit-bashing interface common code	18 jaren geleden
