Refactor OMAP3/4/5 code so that we have only one get_device_type()
function for all platforms.
Details:
- Add ctrl variable for AM33xx and OMAP3 platforms (like it's done for
OMAP4/5), so we can obtain status register in common way
- For now ctrl structure for AM33xx/OMAP3 contains only status register
address
- Run hw_data_init() in order to assign ctrl to proper structure
- Remove DEVICE_MASK and DEVICE_GP definitions as they are not used
(DEVICE_TYPE_MASK and GP_DEVICE are used instead)
- Guard structs in omap_common.h with #ifdefs, because otherwise
including omap_common.h on non-omap4/5 board files breaks compilation
Buildman script was run for all OMAP boards. Result output:
arm: (for 38/616 boards)
all +352.5
bss -1.4
data +3.5
rodata +300.0
spl/u-boot-spl:all +284.7
spl/u-boot-spl:data +2.2
spl/u-boot-spl:rodata +252.0
spl/u-boot-spl:text +30.5
text +50.4
(no errors to report)
Tested on AM57x EVM and BeagleBoard xM.
