omap3: zoom: split board file for software reuse
Browse files Browse the repository at this point in the history 
Split zoom2 board file into a base board file and a board-zoom-peripherals.c
file. That way the same peripherals file can be reused for zoom3 and sdp3630
in addition to zoom2.

Also remove unused struct omap_board_config_kernel entry.

NOTE: Keep the twl4030_madc_platform_data and twl4030_platform_data
entries in board-zoom2.c to avoid merge conflicts with the pending
patches in MFD tree. These entries will be removed later as a fix.

Following list shows the commonality across the three platforms and hence the
case for software reuse:

Peripheral    zoom2    zoom3  sdp3630
---------------------------------------
Ethernet        smsc    smsc    smc
NOR             n/a     n/a     B
Onenand         n/a     n/a     B
HDMI            A       A       B (present on different i2c)
NAND            A       A       A (same nand)
SDRAM           A       A       A (same sdram)
Keypad          A       A       A (same twl)
Camera          A       A       A (same sensor can be mounted)
LCD Display     A       A       A (same wvga display)
OPPs            A       A       A (same chip feature)
Audio           A       A       A (same audio via twl5030)
