Subject: [RFC PATCH v4 0/2] rework of usbgecko-based early debug
Date: Thu, 3 Dec 2009 21:34:58 +0100 [thread overview]
Message-ID: <cover.1259871725.git.albert_herranz@yahoo.es> (raw)
This is v4 of the "early debugging using usbgecko" patch.
It tries to implement the ideas suggested by Benjamin Herrenschmidt
regarding the use of a set of fixmap entries to provide safe
virtual address space for an early mapping.
