prompt "TrustZone interface memory allocator mode"
depends on QCOM_TZMEM default QCOM_TZMEM_MODE_GENERIC
help
Selects the mode of the memory allocator providing memory buffers of
suitable format for sharing with the TrustZone. If in doubt, select 'Generic'.
config QCOM_TZMEM_MODE_GENERIC bool"Generic"
help
Use the generic allocator mode. The memory is page-aligned, non-cachable and physically contiguous.
config QCOM_TZMEM_MODE_SHMBRIDGE bool"SHM Bridge"
help
Use Qualcomm Shared Memory Bridge. The memory has the same alignment as
in the 'Generic' allocator but is also explicitly marked as an SHM Bridge
buffer.
With this selected, all buffers passed to the TrustZone must be allocated using the TZMem allocator orelse the TrustZone will refuse to use them.

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 andregister 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 donot 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.
