This commit modularizes the curve25519 and idgen implementations in the crypto subsystem. Previously, curve25519.c and idgen.c were only compiled when CONFIG_CRYPTO_RANDOM_POOL was enabled. However, cryptosoft.c (used by software cipher support) has a direct dependency on curve25519 functions. This caused linker errors (undefined reference to curve25519) when software crypto was enabled but the random pool was disabled. Changes: - Introduce hidden Kconfig options CRYPTO_CURVE25519 and CRYPTO_IDGEN. - Make CRYPTO_RANDOM_POOL select both CRYPTO_IDGEN and CRYPTO_CURVE25519. - Make CRYPTO_CRYPTODEV_SOFTWARE_CRYPTO/KEYMGMT select CRYPTO_CURVE25519. - Update CMakeLists.txt and Makefile to use the new config flags. This ensures that required algorithms are automatically included in the build regardless of whether the entropy pool is enabled. Signed-off-by: karaketir16 <osmankaraketir@gmail.com>
