Subject: [PATCH v2 00/10] ARM: mstar: Add basic support for i2m and SMP

Sorry for spamming this. I wanted to fix the DT parts
before anyone spent time looking at the DT related commits
in v1.

This series adds basic support for the infinity2m series
of chips. For now the SigmaStar SSD202D which is a dual
Cortex A7 in a QFN128 package.

These chips share most of the same hardware with the
currently supported infinity, infinity3 and mercury5
chips.

Changes since v1:

- Based on Arnd's feedback[0] there is now "mstar,smpctrl" as the 
  most generic compatible string for the smp control registers 
  and a more specific "sstar,ssd201" (yes sstar is right, this is
  a SigmaStar chip) string that is good for the SSD201 and SSD202D
  chips.

- Small code clean ups: remove initialiser for smpctrl, remove unneeded
  #ifdef CONFIG_SMP, make the smp_operations struct static and const.
