Subject: [PATCH 2/9] ARM: modify mach-w90p910.c file for w90p910
Dear Russell,
To change mach-w90p910.c file for w90p910 platform.
At present, I re-arranged my w90x900 series platform architectures, adding 'dev.c' which was used to define the common platform device struct and adding the 'cpu.c' file to implement the common CPU function API, and for the function of specific CPU that were implemented in other file, such as nuc950.c, w90p910.c, due to there are six CPU patches will added to the mach-w90x900, so I think it was distinct to do above.
For above reasons, I modify the 'mach-w90p910.c' file.
