[U-Boot] arm mach-types.h

[Michael Walle]

Hi,

Does u-boot always follow the mach-types.h from upstream linux? Is there any 
policy?

If thats true, it means, that
 - every supported board in u-boot has to be supported in mainline linux,
   too. because that is the basic requirement for an entry to stay in this
   file.
 - a device with device tree bindings, won't have any mach-type entry at all,
   which means, that a distribution is not able to backport a device support
   from DT form to an old-fashioned setup code (eg. support for a board on
   older linux kernels, which doesn't have ARM device tree support).

IMHO u-boot should have its own mach-types.h (maybe autogenerated, like the 
linux kernel do), just with entries for boards which are supported by u-boot. 
This way, there won't be any problems with new board support patches.

Opinions?
