Subject: MPC5200 memory mapped IO
Date: Thu, 22 Feb 2007 17:25:25 -0500 [thread overview]
Message-ID: <45de1855.1b2.2357.4082@cgocable.ca> (raw)
Hi!
I am working on a driver to interface a FPGA chip with the MPC5200 on the local bus plus and I have two questions.
Is it normal that ioremap work without calling mem_request_region before when accessing to mpc5200 registers?
And do I need to call mem_request_region to access to memory mapped device on local bus plus?
Regards,
Fran=e7ois
