Confirmed no impact on the Thumb2 code, but did need to change which .c files were used.
Tried to test on an STM32MP135 (cortex-a7) using:
./configure --host=armv7a CC="arm-linux-gnueabi-gcc" AR="arm-linux-gnueabi-ar" RANLIB="arm-linux-gnueabi-ranlib" --enable-sp=yes,asm --enable-keygen --enable-armasm=inline --enable-keygen --enable-curve25519 --enable-ed25519 --disable-shared --enable-static --disable-dh --disable-filesystem CPPFLAGS="-DWOLFSSL_ARMASM_NO_NEON" --disable-sha3 && make
Can you share an example of how you cross-compile?

About a 30% improvement without NEON.

Errors not finding the implementations for GCM_gmult_len, AES_set_encrypt_key, AES_CBC_encrypt, AES_CBC_decrypt, AES_ECB_encrypt, etc...
Due to A7 needing WOLFSSL_ARMASM_NO_HW_CRYPTO. These are in the armv8-32-aes-asm or thumb2-aes-asm.
Seems the BUILD_ARMASM_CRYPTO may not be required anymore. This patch worked for PR and master:
