[PATCH] arm64: defconfig: Ensure CRYPTO_CHACHA20_NEON is selected

[PATCH] arm64: defconfig: Ensure CRYPTO_CHACHA20_NEON is selected

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

Since commit 17ec3e71ba79 ("crypto: lib/Kconfig - Hide arch options from
user"), the CRYPTO_CHACHA20_NEON option is no longer selected by default
due to changes in how crypto library options are exposed and selected.

To restore the previous behavior and ensure CRYPTO_CHACHA20_NEON is
enabled, explicitly select CONFIG_CRYPTO_CHACHA20 in the defconfig. This
pulls in CRYPTO_LIB_CHACHA_INTERNAL and allows CRYPTO_CHACHA20_NEON to be
selected automatically as before.

Fixes: 17ec3e71ba79 ("crypto: lib/Kconfig - Hide arch options from user")

in case Herbert wants to pick this up as a fix for the crypto tree,
or I can apply this through arm-soc if you send a copy to soc@lists.linux.dev.

Going through arm-soc should be fine.  I don't see any changes
in my tree that should create a non-trivial conflict with this.

Thanks,
