The CAAM on IMX7ULP doesn't support public key hardware acceleration (PKHA), as in other NXP parts. Disable RSA_FREESCALE_EXP for IMX7ULP too.

Fixed: f4e9ff7135 ("Kconfig: Don't use RSA_FREESCALE_EXP on IMX") Signed-off-by: Ricardo Salveti ricardo@foundries.io Signed-off-by: Oleksandr Suvorov oleksandr.suvorov@foundries.io ---

Changes in v2: - add a dependency rule for RSA_FREESCALE_EXP
