Abstracted out part of the concept of an SPI device to a generalised NVS 2006-12-04T18:23:06+00:00 Michael Brown 2006-12-04T18:23:06+00:00 urn:sha1:946967f09ce0ab9ab438a0647d393601dd0fca23 device. 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 than 2006-12-04T16:09:59+00:00 Michael Brown 2006-12-04T16:09:59+00:00 urn:sha1:dc06c895fc089bcb9c050b2fb64494213f61e896 a word length. Generalised the SPI abstraction layer to also be able to handle interfaces 2006-12-04T15:36:51+00:00 Michael Brown 2006-12-04T15:36:51+00:00 urn:sha1:931f94dca30b04f8303acdcfd08436e61a491a92 that don't provide the full flexibility of a bit-bashing interface. Temporarily hacked rtl8139.c to use the new interface. We don't actually have a stdio.h header file.

(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 compilation 2006-09-27T05:57:06+00:00 Marty Connor 2006-09-27T05:57:06+00:00 urn:sha1:6ac78f6aff85b2a41d1c98011c41f622d569076a Generalise three-wire interface to generic SPI interface. 2006-06-14T00:22:50+00:00 Michael Brown 2006-06-14T00:22:50+00:00 urn:sha1:3b51c719d305d4bfe8e99003f28d7cd48e0d9f4e Update rtl8139 driver to instantiate an SPI interface with a three-wire device attached.
