The typedef and definitions are generated by the OBJECT_DECLARE_TYPE
macro in "hw/arm/bcm2836.h":
20 #define TYPE_BCM283X "bcm283x"
21 OBJECT_DECLARE_TYPE(BCM283XState, BCM283XClass, BCM283X)
The script ran in commit a489d1951c ("Use OBJECT_DECLARE_TYPE when
possible") missed them because they are declared in a different
file unit. Remove them.
