[RFC 0/4] Cleanup PRM and CM regbit headers

[Rajendra Nayak]

Hi,

Over the years the PRM and CM headers for OMAP have been growing largely
due to autogeneration which creates headers for complete PRM and
CM register space, regardless of the actual usage of these registers in
software.

The latest master on linux-omap (which also happens to have the OMAP5 data)
show these stats for the prm-regbits-*.h and cm-regbits-*.h alone. Not to mention
there are other PRM/CM related headers which I am yet to look at.

6285
a0131687 at ula0131687:~/oldhome/repos/github/linux$ cat arch/arm/mach-omap2/cm-regbits-*.h | wc -l 
5556

Using some simple awk/grep scripting I cleaned these headers to retain only the defines that
are currently used and that changes the stats to this below.

352
a0131687 at ula0131687:~/oldhome/repos/github/linux$ cat arch/arm/mach-omap2/cm-regbits-*.h | wc -l
661

I am sharing this RFC just to take the discussion forward on how to handle these files, and many
others which are also autogenerated, given we have newer SoCs coming up for which the autogen output
ends up creating even larger files.
