I don't think that it's mandatory. Without phys_* parameters, just
dynamic allocation from non-reserved area would be used. This may
sometimes suffer from memory allocation, especially in the case that
the target board has small amount of memory(RAM).

The above is a bit different from mine as below, where the count of
mailbox interrupt are incremented reasonably.
bridge:~$ modprobe bridgedriver base_img=ddspbase_tiomap3430.dof64P
bridge:~$ grep DspBridge /proc/interrupts
26: 3 INTC DspBridge mailbox
28: 0 INTC DspBridge iommu fault
bridge:~$ ./ping.out > /dev/null
bridge:~$ grep DspBridge /proc/interrupts
26: 169 INTC DspBridge mailbox
28: 0 INTC DspBridge iommu fault
bridge:~$ ./ping.out > /dev/null
bridge:~$ grep DspBridge /proc/interrupts
26: 334 INTC DspBridge mailbox
28: 0 INTC DspBridge iommu fault
bridge:~$
You can see how it's working by appending GT_str="**=01234567" on
module parameter to investigate further.
