The convention that we've been using is: 10004000-10004fff : mb:aaci 10004000-10004fff : aaci-pl041 10005000-10005fff : mb:mmci 10005000-10005fff : mmci-pl18x 10006000-10006fff : mb:kmi0 10006000-10006fff : kmi-pl050 10007000-10007fff : mb:kmi1 10007000-10007fff : kmi-pl050 10009000-10009fff : mb:uart0 10009000-10009fff : uart-pl011 1000a000-1000afff : mb:uart1 1000a000-1000afff : uart-pl011 1000b000-1000bfff : mb:uart2 1000b000-1000bfff : uart-pl011 1000c000-1000cfff : mb:uart3 1000c000-1000cfff : uart-pl011 The parent resource uses the device name. The child resource is the driver name. That (a) avoids useless duplication of data in /proc/iomem and (b) is more informative when you look at /proc/iomem about what's where.
