Subject: [PATCH] sh: maple: Add support for VMU devices (v2) [0/3]
Date: Tue, 03 Feb 2009 00:06:09 +0000 [thread overview]
Message-ID: <1233619569.13918.12.camel@localhost.localdomain> (raw)
This series of patches adds support for the Dreamcast Visual Memory
Unit, reworking the maple bus code to ensure it supports asynchronous
reads and writes. A consequential amendment to the keyboard driver is
also included.
The VMU is a 'smart' flash chip where access is controlled by a
microcontroller so that, for instance, flash erases appear to be
transparent to the end user. The VMU does, however, show typical
flash-type behaviour (eg phased writes) and the MTD layer and the chip
work well together (eg in the way they handle apparent hotplug events
during a block write).
