Ard Biesheuvel 3f368b886e crypto: amlogic-gxl - default to build as module
The AmLogic GXL crypto accelerator driver is built into the kernel if
ARCH_MESON is set. However, given the single image policy of arm64, its
defconfig enables all platforms by default, and so ARCH_MESON is usually
enabled.

This means that the AmLogic driver causes the arm64 defconfig build to
pull in a huge chunk of the crypto stack as a builtin as well, which is
undesirable, so let's make the amlogic GXL driver default to 'm' instead.

Select y here to have support for the cryptographic offloader
available on Amlogic GXL SoC.
This hardware handles AES ciphers in ECB/CBC mode.
To compile this driver as a module, choose M here: the module
will be called amlogic-gxl-crypto.
config CRYPTO_DEV_AMLOGIC_GXL_DEBUG
bool "Enable amlogic stats"

depends on DEBUG_FS
help
Say y to enable amlogic-crypto debug stats.
This will create /sys/kernel/debug/gxl-crypto/stats for displaying
the number of requests per flow and per algorithm.
