dm: core: Fix address translation in devfdt_get_addr_index()

2024-03-04T15:25:47+00:00

During address translation #address/size-cells props are expected to
apply to child nodes. However, devfdt_get_addr_index() incorrectly use
the parent offset of the udevice parent instead of getting the offset of
the node parent. This will work in most cases when there is only one
udevice tied to a node.

On e.g. an Orange Pi R1 Plus TLS board the dwc3-generic (parent) and
dwc3-generic-host (child) udevice is tied to the same node.

In that case both the offset and parent values end up being the same.
As a result, the #address/size-cells props intended for child nodes
incorrectly gets applied to the node itself resulting in wrong addr
being returned, 0x0 instead of 0xff600000.

The following can be seen on console:

  dwc3-generic-host usb@ff600000: this is not a DesignWare USB3 DRD Core
  dwc3-generic-host usb@ff600000: failed to initialize core

Fix this by using the offset of the parent node and not the offset to
the node the parent udevice is tied to.

fdt: Check for a valid fdt in oftree_ensure()

Check the header before starting to use it, since this could provide
very confusing later, when ofnode calls start to fail.

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.

spl: Allow enabling SPL_OF_REAL and SPL_OF_PLATDATA at the same time

2023-10-18T00:50:52+00:00

Sandbox unit tests in U-Boot proper load a test device tree to have some
devices to work with. In order to do the same in SPL, we must enable
SPL_OF_REAL. However, we already have SPL_OF_PLATDATA enabled. When
generating platdata from a devicetree, it is expected that we will not need
devicetree access functions (even though SPL_OF_CONTROL is enabled). This
expectation does not hold for sandbox, so allow user control of
SPL_OF_REAL.

There are several places in the tree where conditions involving OF_PLATDATA
or OF_REAL no longer function correctly when both of these options can be
selected at the same time. Adjust these conditions accordingly.

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.
