There is no hook anywhere that would trigger when running a command
like

	md 0xFF000000 0x100000

which actually might cross "bank" boundaries that require  tofggeling
of I/O lines. addr2info() is nowhere used in such a szenario. [And it
shall  not  be  used,  as "md" and friends are supposed to operate on
plain memory, exactly as their counterparts in a JTAG debugger  would
do.]

Best regards,
