[U-Boot] [PATCH] ARM: at91: sama5d2: Wrap cpu detection to fix macb driver

[Alexander Dahl]

Hei hei,

my use of git send-email messed up my original cc list, so I add Eugen

I'm not sure if those macros for checking on certain cpu types are a
good solution at all, other code parts seem to distinguish things by
CONFIG_* variables.

The Linux kernel driver sets cap flags based on the dt compat strings.
I consider that a good approach in general, but I don't know if that's
a way for the U-Boot driver model, too?
