(i.e. LSB transmitted first on the wire), even though SPI commands and
addresses always have to be big-endian.
Abstracted out part of the concept of an SPI device to a generalised NVS2006-12-04T18:23:06+00:00Michael Brown2006-12-04T18:23:06+00:00urn:sha1:946967f09ce0ab9ab438a0647d393601dd0fca23

Separated the mechanisms of non-volatile storage access and non-volatile
stored options.
Changed length parameter in SPI methods to be a byte length, rather than2006-12-04T16:09:59+00:00Michael Brown2006-12-04T16:09:59+00:00urn:sha1:dc06c895fc089bcb9c050b2fb64494213f61e896

Generalised the SPI abstraction layer to also be able to handle interfaces2006-12-04T15:36:51+00:00Michael Brown2006-12-04T15:36:51+00:00urn:sha1:931f94dca30b04f8303acdcfd08436e61a491a92

Temporarily hacked rtl8139.c to use the new interface.
We don't actually have a stdio.h header file. Our printf() functions are2006-09-27T10:58:14+00:00Michael Brown2006-09-27T10:58:14+00:00urn:sha1:88e38fa1483891f273f063f92ef71a5c33fe5406
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.
added stdio.h to includes for DBG compilation2006-09-27T05:57:06+00:00Marty Connor2006-09-27T05:57:06+00:00urn:sha1:6ac78f6aff85b2a41d1c98011c41f622d569076aGeneralise three-wire interface to generic SPI interface.2006-06-14T00:22:50+00:00Michael Brown2006-06-14T00:22:50+00:00urn:sha1:3b51c719d305d4bfe8e99003f28d7cd48e0d9f4e
Update rtl8139 driver to instantiate an SPI interface with a three-wire
device attached.
Move per-transition delays from generic bit-bashing layer to i2c layer2006-06-14T00:20:35+00:00Michael Brown2006-06-14T00:20:35+00:00urn:sha1:ab4f96e525fe082b0750867cc50d03becf018048
(since SPI bit-bashing will require different delay semantics).
Change read_bit() to return 0 or -1UL, rather than 0 or 1.2006-06-12T19:29:50+00:00Michael Brown2006-06-12T19:29:50+00:00urn:sha1:51a36f1cfbb45609c5e50b2257f4030b956316ae
