Subject: [PATCH] alpha: add io{read,write}{16,32}be functions
|
|
Date: Wed, 30 Nov 2011 21:01:40 +1300
|
|
Message-Id: <1322640100-14534-1-git-send-email-mcree@orcon.net.nz>

|
These functions are used in some PCI drivers with big-endian
|
|
MMIO space.
|
|
|
|
Admittedly it is almost certain that no one this side of the
|
|
Moon would use such a card in an Alpha but it does get us
|
|
closer to being able to build allyesconfig or allmodconfig,
|
|
and it enables the Debian default generic config to build.
