Subject: [Qemu-devel] PATCH: Longword read/write to eepro100's eeprom
Date: Thu, 02 Apr 2009 08:52:26 -0400 [thread overview]
Message-ID: <1238676746.18745.2.camel@nibbler.dlib.indiana.edu> (raw)
It looks like the alpha-softmmu target tries to read/write the eeprom
using longword addressing. This patch catches that case and redirects
the reads/writes to the eeprom.
