Subject: [U-Boot] Driver data in u-boot
Date: Sat, 29 Oct 2011 02:03:33 -0700 (PDT) [thread overview]
Message-ID: <32742826.post@talk.nabble.com> (raw)
I am trying to write a spi bus driver for an arm board. Different boards from
the same vendor
are likely to have more than one instance of the controller.
So I am attempting to write a portable driver for all instances on a board.
However each board is going to have different config data like gpio numbers,
clock freq plan etc. Can I maintain these as read only global data in board
specific files
and declare them as externs in the driver implementation
I realize this is an implementation/design question,
but I believe there are some guidelines regarding use of global data in
u-boot.
My understanding is that this approach conforms to those guidelines but
correct me
if im wrong.
