[Qemu-devel] PATCH: Longword read/write to eepro100's eeprom

[Qemu-devel] PATCH: Longword read/write to eepro100's eeprom

[Brian Wheeler]

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.
