Mark Brown 4e5e1eb89f arm64: dts: Reduce size of virtio block device for foundation model
Will Deacon observed that kvmtool uses a size of 0x200 for virtio
block memory region and that the virtio block spec only uses 31 bytes in
the device specific region at 0x100 so reduce the region to a less
wasteful 0x200.

Catalin Marinas df503ba7f6 arm64: dts: Reserve the memory used for secondary CPU release address
With the spin-table SMP booting method, secondary CPUs poll a location
passed in the DT. The foundation-v8.dts file doesn't have this memory
reserved and there is a risk of Linux using it before secondary CPUs are
started.

Mark Rutland ed1f23637a arm64: dts: fix #address-cells for foundation-v8
Commit 90556ca1 ("arm64: vexpress: Add dts files for the ARMv8 RTSM
models") added foundation-v8.dts, but erroneously set
/cpus/#address-cells = <1> while providing two cells in each cpus/cpu@N
node's reg property.

As of commit ea393a2e ("arm64: smp: honour #address-size when parsing
CPU reg property") we read in as many address cells as specified rather
than always reading two. This means that for foundation-v8.dts, we only
read the first reg cell (zero) for each cpu node, and receive a lot of
warnings at boot of the form "/cpus/cpu@1: duplicate cpu reg properties
in the DT".

This patch corrects foundation-v8.dts to have the correct value for
/cpus/#address-cells.

Stephen Warren d0b6a548f7 arm64: dts: prevent *.dtb from always being rebuilt
if_changed (used by the *.dts->*.dtc rule) rebuilds files if they aren't
contained in $(targets). (make V=2 indicates this). Add $(dtb-y) to
$(targets) to prevent *.dtb from always being rebuilt. Note

This fixes a regression introduced by the .dtb rule rework in da4cbc6
"arm64: use new common dtc rule", although since arm64 doesn't actually
have any *.dts yet, this isn't a critical issue.

Stephen Warren da4cbc6d58 arm64: use new common dtc rule
The current rules have the .dtb files build in a different directory
from the .dts files. This patch changes arm64 to use the generic dtb
rule which builds .dtb files in the same directory as the source .dts.

This requires moving parts of arch/arm64/boot/Makefile into newly created
arch/arm64/boot/dts/Makefile, and updating arch/arm64/Makefile to call the
new Makefile.
