yes, in your example, the fines in conf/machine/include are common to all omap 
boards (and even all cortexa8 for tune-cortexa8.inc) and thus when fixing one 
BSP you have to think to fix the others (and to communicate the fix to other 
BSP maintainers).
The same apply for most of the .inc in recipes-bsp/*/.

Do you think the following setup is possible ?

- ARM overlay (containing all generic files for ARM achitecture : 
conf/machines/include for example)

- OMAP3 overlay (containing all generic files for OMAP3 SOC : 
conf/machines/include/omap* + recipes/linux u-boot x-load base files for omap3 
architecture,

- specific board overlay (conf/machine/themachine.conf + board specific 
additions in recipes/linux u-boot & x-load (with patches based on top of the 
OMAP3 overlay).
