[PATCH 1/2] hw: Fix problem with the A*MPCORE switches in the Kconfig files

Thomas Huth posted 2 patches 10 months, 1 week ago
There is a newer version of this series
[PATCH 1/2] hw: Fix problem with the A*MPCORE switches in the Kconfig files
Posted by Thomas Huth 10 months, 1 week ago 
A9MPCORE, ARM11MPCORE and A15MPCORE are defined twice, once in
hw/cpu/Kconfig and once in hw/arm/Kconfig. This is only possible
by accident, since hw/cpu/Kconfig is never included from hw/Kconfig.
Fix it by declaring the switches only in hw/cpu/Kconfig (since the
related files reside in the hw/cpu/ folder) and by making sure that
the file hw/cpu/Kconfig is now properly included from hw/Kconfig.

I thought

  was already merged :/ I'll look at what is missing and respin.

Oh, ok. But I'd prefer to keep the hw/cpu/Kconfig file since it will be used 
in the 2nd patch here, too.
