Sorry, that was separate patch in the series:

You enable 64 bit addressing (64b dma bus width) always when appropriate
architecture config option is enabled.
But there are some legacy controllers w
This patch adds support for 64 bit addressing and BDs.
-> Enable 64 bit addressing in DMACFG register.
-> Set DMA mask when design config register shows support for 64 bit addr.
-> Add new BD words for higher address when 64 bit DMA support is present.
-> Add and update TBQPH and RBQPH for MSB of B
