Merge tag 'atlas7-lldebug-for-3.20' of git://git.kernel.org/pub/scm/linux/kernel/git/baohua/linux into next/soc

Merge "CSR atlas7 debug ports for 3.20" from Barry Song:

add debug ports for CSRatlas7 SoC

Because Marco chip has never shipped to customers and has been replaced
by Atlas7, so we do the below
- drop Marco's debug port
- add debug ports for Atlas7

* tag 'atlas7-lldebug-for-3.20' of git://git.kernel.org/pub/scm/linux/kernel/git/baohua/linux:
  ARM: sirf: add two debug ports for CSRatlas7 SoC
  ARM: sirf: drop Marco low-level debug port
