Michael Brown	6ceaa158da	Return -EIO when verification fails, instead of -EINVAL.	2006-12-20 14:11:50 +00:00
Michael Brown	d2bf7abe75	Added write support for three-wire devices (e.g. the RTL8139 EEPROM)	2006-12-06 19:51:58 +00:00
Michael Brown	ac401f481d	Verify data after writing	2006-12-06 18:51:31 +00:00
Michael Brown	6b45947a59	Added debug statements	2006-12-04 23:20:56 +00:00
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.	2006-12-04 22:06:54 +00:00
Michael Brown	2d8d21fe74	Added the generic block-splitting code to nvs.c	2006-12-04 19:06:07 +00:00
Michael Brown	1961ba44e1	Added generic SPI protocol handler with read and write support.	2006-12-04 18:32:55 +00:00
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.	2006-12-04 18:23:06 +00:00
Michael Brown	dc06c895fc	Changed length parameter in SPI methods to be a byte length, rather than ... a word length.	2006-12-04 16:09:59 +00:00
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.	2006-12-04 15:36:51 +00:00
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.	2006-06-14 00:22:50 +00:00
Michael Brown	aa2468babe	Added abstraction layer for a three-wire serial device (e.g. the EEPROM ... used on RTL8139 cards).	2006-05-26 15:39:24 +00:00
