On my tests:
Prior to this patch: with the internal ROM SDMA firmware I got UART issues when communicating through a Bluetooth module. With external SDMA firmware (version 3.1) it worked fine.
With your patch applied: Bluetooth worked fine even with no external SDMA firmware, which does not match the comments you added.
Can't you just remove these comments?
Thanks
