IIUC, the only board that uses ARM DCC serial is the Zynq, and it
gets it to work by #define'ing CONFIG_CPU_V6 in its include config
file despite being ARMv7. Am I right in assuming this #define was
actually a hack to get around the issue you're fixing here, and that it
can and should be removed from the Zinq include? If so, can you please
post a v2 of your patch which does the removal too?

(BTW, no need for a cover letter when there's only one patch in the
"series" IMO)

Amicalement,
