headers: don't depend on errno.h being available

2024-01-24T16:12:11+00:00

These headers follow the pattern:

| #if CONFIG_IS_ENABLED(FANCY_FEATURE)
|   void foo(void);
| #else
|   static inline void foo(void) { return -ENOSYS; }
| #endif

In the #else path ENOSYS is used, however linux/errno.h is not included.
If errno.h has not been included already the compiler errors out even
if the inline function is not referenced.

Make those headers self contained.

dm: Do not enable debug messages by default

2023-11-15T03:04:01+00:00

CONFIG_DM_WARN has a text indicating that these messages should only
provided when debugging. This implies that the setting must be default no.

We should still create debug messages.

serial: zynqmp: Fetch baudrate from dtb and update

2023-11-07T12:47:08+00:00

The baudrate configured in .config is taken by default by serial. If
change of baudrate is required then the .config needs to changed and
u-boot recompilation is required or the u-boot environment needs to be
updated.

To avoid this, support is added to fetch the baudrate directly from the
device tree file and update.
The serial, prints the log with the configured baudrate in the dtb.
The commit c4df0f6f315c ("arm: mvebu: Espressobin: Set default value for
$fdtfile env variable") is taken as reference for changing the default
environment variable.

The default environment stores the default baudrate value, When default
baudrate and dtb baudrate are not same glitches are seen on the serial.
So, the environment also needs to be updated with the dtb baudrate to
avoid the glitches on the serial.

Also add test to cover this new function.

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.

firmware: scmi: implement SCMI base protocol

2023-10-13T20:59:23+00:00

SCMI base protocol is mandatory according to the SCMI specification.

With this patch, SCMI base protocol can be accessed via SCMI transport
layers. All the commands, except SCMI_BASE_NOTIFY_ERRORS, are supported.
This is because U-Boot doesn't support interrupts and the current transport
layers are not able to handle asynchronous messages properly.

core: return FDT_ADDR_T_NONE from devfdt_get_addr_[size_]name() on errors

2023-10-13T17:15:41+00:00

Checking for the error cast to fdt_addr_t is rather awkward - IS_ERR()
can be used, but it's not really made to be used on fdt_addr_t, which
may not even be the same size as a native pointer.

Most places in U-Boot only check for FDT_ADDR_T_NONE; let's adjust the
error return to match the expectation.
