Subject: [RFC PATCH v3 0/3] rework of usbgecko-based early debug
Date: Tue, 1 Dec 2009 00:09:47 +0100 [thread overview]
Message-ID: <cover.1259609263.git.albert_herranz@yahoo.es> (raw)
This series is a rework of the previously posted patch:
- [RFC PATCH v2 08/11] powerpc: gamecube/wii: early debugging using usbgecko
It tries to implement the ideas suggested by Benjamin Herrenschmidt
regarding the use of a fixmap entry to provide a valid I/O mapping
immediately after MMU_init runs and MMU is definitively enabled.
Albert Herranz (3):
powerpc: udbg: add early remap hook
powerpc: udbg: add fixmap entry for early debug
powerpc: gamecube/wii: early debugging using usbgecko
