RFC TI: OMAP3: Use common config file.

Hi all,

Most of the boards based on TI processors uses common configuration files (ti_armv7_common.h, ti_<processor>_common.h) to avoid duplication of code. This is right except for OMAP3-based boards. In order to use the same schema as used on am33xx, omap4, omap5 and dra7 TI processors these patches create a new ti_omap3_common.h (that include ti_armv7_common.h) with the purpose that all OMAP3 board can use it.

Patches 1 and 2 just renames current omap4|omap5_common.h to ti_omap4|omap5_common.h to be coherent with current ti_am33xx_common.h, ti_armv7_common.h and the new ti_omap3_common.h. It's just a cosmetic change so if people don't like it I don't have any inconvenient to remove from these series.

Patches 3 and 4 modifies the ti_armv7_common.h to be more compatible with OMAP3 boards. For example, patch 3 removes the assumption that all ti_armv7 have an ELM hardware engine and patch 4 handles the case that the number of DRAM banks is defined at board level. The patch 5 is also required to integrate the use of ti_armv7_common.h on OMAP3 boards.

Patch 6 creates the new ti_omap3_common.h to be used for any OMAP3-based board.

And finally, patch 7 moves the IGEP boards to use the new common file. As I only have IGEP hardware to test these patches I decided only implement the use case for these boards. I don't have any inconvenient to move other OMAP3 boards to use this schema but I prefer leave the decision to the board maintainers.

Any comments, improvements, fixes are welcome.

Best regards,
