Re: [Xen-devel] [PATCH v4 08/10] arm: add QEMU, Rcar3 and MPSoC configs
Hi Stefano,
Sorry for formatting. Add a "Platform Support" menu with three umbrella kconfig options: QEMU,
RCAR3 and MPSOC. They enable the required options for their hardware
platform.
This patch is nothing close to what we discussed. As far as I can tell, the tiny.config will end up to select all the platforms with their driver. It will not be possible to deselect the driver selected for a platform afterwards.
I still think the best if providing a choice list where only one option can be selected. I would like to understand why you didn't go this path.
Cheers,
In the case of the MPSOC that has a platform file under
arch/arm/platforms/, build the file if MPSOC.

Changes in v4:
- fix GICv3/GICV3
- default y to all options
- build xilinx-zynqmp if MPSOC
