Future U-Boot 2026.07 will build mkeficapsule with pkcs11 support. [1]
This causes link errors with Buildroot, such as the following one:
mkeficapsule.c:(.text.startup+0xcd3): undefined reference to `gnutls_pkcs11_init'
(Other symbols the linker complains about are: gnutls_pkcs11_add_provider,
gnutls_pkcs11_obj_list_import_url4, gnutls_x509_crt_import_pkcs11 and
gnutls_pkcs11_deinit.)
The following example commands can be used to reproduce the issue:
make qemu_aarch64_ebbr_defconfig
echo 'BR2_TARGET_UBOOT_CUSTOM_VERSION_VALUE="2026.07-rc3"' >>.config
echo 'BR2_TARGET_UBOOT_NEEDS_GNUTLS=y' >>.config
echo '# BR2_DOWNLOAD_FORCE_CHECK_HASHES is not set' >>.config
make olddefconfig
make uboot
This commit adds the pkcs11 support for host-gnutls.
In Buildroot, since host-gnutls is currently only needed by uboot
(and other uboot derivatives such as uboot-tools) the pkcs11 support
is added unconditionally to host-gnutls.
