Kconfig: Make further use of testing for !COMPILE_TEST

2025-10-08T22:12:41+00:00

We have a large number of library symbols that should not be prompted
for by the user really but rather selected by the platform (or SoC) as
needed. To start with however, make these depend on !COMPILE_TEST.

drivers: introduce Secure Monitor uclass

2023-10-15T10:23:48+00:00

At the moment, we don't have a common API for working with
SM, only the smc_call() function. This approach is not generic
and difficult to configure and maintain.

This patch adds UCLASS_SM with the generic API:

- sm_call()
- sm_call_write()
- sm_call_read()

These functions operate with struct pt_regs, which describes
Secure Monitor arguments.

bios_emulator: Add Kconfig and adjust Makefile for SPL

2023-07-17T09:08:44+00:00

The Kconfig for this is currently inside a particular board. Move it into
the correct place and allow use in SPL, so that video can be used there
if needed.

FWU: Add support for the FWU Multi Bank Update feature

2022-10-31T18:47:32+00:00

The FWU Multi Bank Update feature supports updating firmware images
to one of multiple sets(also called banks) of images. The firmware
images are clubbed together in banks, with the system booting images
from the active bank. Information on the images such as which bank
they belong to is stored as part of the metadata structure, which is
stored on the same storage media as the firmware images on a dedicated
partition.

At the time of update, the metadata is read to identify the bank to
which the images need to be flashed(update bank). On a successful
update, the metadata is modified to set the updated bank as active
bank to subsequently boot from.

iommu: Add IOMMU uclass

2021-10-31T12:46:44+00:00

This uclass is intended to manage IOMMUs on systems where the
IOMMUs are not in bypass mode by default.  In that case U-Boot
cannot ignore the IOMMUs if it wants to use devices that need
to do DMA and sit behind such an IOMMU.

This initial IOMMU uclass implementation does not implement and
device ops and is intended for IOMMUs that have a bypass mode
that does not require address translation.  Support for IOMMUs
that do require address translation is planned and device ops
will be defined when support for such IOMMUs will be added.

reboot-mode: add support for reboot mode control

2021-07-23T14:16:39+00:00

A new driver uclass is created to handle the reboot mode control.

The new uclass driver is updating an environment variable with the
configured reboot mode. The mode is extracted from a map provided
at initialization time. The map contains a list of modes
and associated ids.
