[PATCH RFC INTERNAL 0/2] soc: renesas: Introduce ARCH_RENESAS_ARM64

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Hi All,

This an attempt to fix adding each SoCs to ARM64 defconfig file
by introducing ARCH_RENESAS_ARM64.

As an attempt I have just added it for ARM64 if we are OK we can
proceed with ARM32 too.

Cheers,
Prabhakar

[PATCH RFC INTERNAL 1/2] soc: renesas: Add ARCH_RENESAS_ARM64 Kconfig option

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Introduce a new `ARCH_RENESAS_ARM64` Kconfig option to simplify the
selection of all ARM64-based Renesas SoCs. This allows for easier
configuration when building kernels for multiple Renesas ARM64 platforms
by selecting a single option instead of enabling each SoC individually.

[PATCH RFC INTERNAL 2/2] arm64: defconfig: Use ARCH_RENESAS_ARM64 to enable all Renesas ARM64 SoCs

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Replace individual SoC-specific `CONFIG_ARCH_*` entries for Renesas ARM64
platforms with the newly introduced `CONFIG_ARCH_RENESAS_ARM64` option.
This change simplifies the defconfig by enabling all Renesas ARM64 SoCs
with a single configuration option, improving maintainability and reducing
the risk of missing SoCs when updating the defconfig.

Why not use 'default y if ARCH_RENESAS' as suggested here:

?

Agreed, let me test that out and send a v2.
