linux.git/arch/arm/kernel/debug.S, branch v2.6.37 Linux kernel source tree arm: return both physical and virtual addresses from addruart 2010-10-20T04:27:33+00:00 Jeremy Kerr jeremy.kerr@canonical.com 2010-07-06T10:30:06+00:00 0ea1293009826da45e1019f45dfde1e557bb30df Rather than checking the MMU status in every instance of addruart, do it once in kernel/debug.S, and change the existing addruart macros to return both physical and virtual addresses. The main debug code can then select the appropriate address to use. This will also allow us to retreive the address of a uart for the MMU state that we're not current in.
