+config QCOM_SCM_DOWNLOAD_MODE_DEFAULT
+	bool "Qualcomm download mode enabled by default"
+	depends on QCOM_SCM
+	help
+	  A device with "download mode" enabled will upon an unexpected
+	  warm-restart enter a special debug mode that allows the user to
+	  "download" memory content over USB for offline postmortem analysis.
+	  The feature can be enabled/disabled on the kernel command line.
+
+	  Say Y here to enable "download mode" by default.
+
+config QCOM_QSEECOM
+	bool "Qualcomm QSEECOM interface driver"
+	depends on QCOM_SCM=y
+	select AUXILIARY_BUS
+	help
+	  Various Qualcomm SoCs have a Secure Execution Environment (SEE) running
+	  in the Trust Zone. This module provides an interface to that via the
+	  QSEECOM mechanism, using SCM calls.
+
+	  The QSEECOM interface allows, among other things, access to applications
+	  running in the SEE. An example of such an application is 'uefisecapp',
+	  which is required to access UEFI variables on certain systems. If
+	  selected, the interface will also attempt to detect and register client
+	  devices for supported applications.
+
+	  Select Y here to enable the QSEECOM interface driver.
+
+config QCOM_QSEECOM_UEFISECAPP
+	bool "Qualcomm SEE UEFI Secure App client driver"
+	depends on QCOM_QSEECOM
+	depends on EFI
+	help
+	  Various Qualcomm SoCs do not allow direct access to EFI variables.
+	  Instead, these need to be accessed via the UEFI Secure Application
+	  (uefisecapp), residing in the Secure Execution Environment (SEE).
+
+	  This module provides a client driver for uefisecapp, installing efivar
+	  operations to allow the kernel accessing EFI variables, and via that also
+	  provide user-space with access to EFI variables via efivarfs.
+
+	  Select Y here to provide access to EFI variables on the aforementioned
+	  platforms.
