firmware: qcom: move Qualcomm code into its own directory
We're getting more and more qcom specific .c files in drivers/firmware/ and about to get even more. Create a separate directory for Qualcomm firmware drivers and move existing sources in there.

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. | ||

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. | ||
|

bool "Qualcomm SEE UEFI Secure App client driver" | ||

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. | ||
