[PATCH 0/3] arm64: tegra: Make ARCH_TEGRA_SOC_FOO defaults for Nvidia Tegra

[PATCH 0/3] arm64: tegra: Make ARCH_TEGRA_SOC_FOO defaults for Nvidia Tegra

[Krzysztof Kozlowski]

Renesas was fixed (thanks folks!), so let's fix this one myself.

By convention, only one globally selectable ARCH_PLATFORM is expected
for given SoC platform, defined in arch/arm64/Kconfig.platforms or
arch/arm/mach-*/Kconfig, because we target a single multi-platform
kernel image.

Dependency
==========
Further (2 and 3) patches depend on the first one, so should be taken
via one branch or some cross-branch-merges.

Best regards,
Krzysztof

[PATCH 1/3] soc: tegra: Make ARCH_TEGRA_SOC_FOO defaults for Nvidia Tegra

[Krzysztof Kozlowski]

By convention, only one globally selectable ARCH_PLATFORM is expected
for given SoC platform, defined in arch/arm64/Kconfig.platforms or
arch/arm/mach-*/Kconfig, because we target a single multi-platform
kernel image.

Platforms wanting different granularity, e.g. due to size constraints on
their devices, should be sure that globally only one ARCH_PLTAFORM is
selected in defconfig.  Change Tegra per-soc Kconfig entries to default
to ARCH_TEGRA allowing removal of these per-soc parts from defconfigs.

1. All further patches depend on this one.
2. Year ago after my complains Prabhakar fixed another case - Renesas -
   so with this patch we get rid of all single-ARCH offenders.

[PATCH 2/3] ARM: tegra: defconfig: Drop redundant ARCH_TEGRA_foo_SOC

[Krzysztof Kozlowski]

All CONFIG_ARCH_TEGRA_2x_SOC-like symbols are now default for
ARCH_TEGRA, so drop redundant lines from defconfigs.  Tested with
comparing include/generated/autoconf.h.

Sounds like a bit of a made-up convention to me. I don't have a strong
objection, though, so feel free to go ahead with this.

Maybe we should ask Arnd to pick up this series into ARM SoC for 7.0?
Most ARM SoC stuff should be merged at this point and since this is
essentially just a bit of cleanup merging this now would avoid any
potential conflicts for 7.1.

In any case, the series:
