lib: acpi: Fix linking SPL when ACPIGEN is enabled

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

lib/acpi/acpigen.o is only compiled into SPL when SPL_ACPIGEN is enabled.
Update several files which reference these functions accordingly.

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: introduce dev_read_addr_name[_size]_ptr() functions

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

Same as dev_read_addr_name[_size](), but returns a pointer, cast
through map_sysmem().

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.

pci: serial: Support reading PCI-register size with base

2023-10-06T18:38:13+00:00

The PCI helpers read only the base address for a PCI region. In some cases
the size is needed as well, e.g. to pass along to a driver which needs to
know the size of its register area.

Update the functions to allow the size to be returned. For serial, record
the information and provided it with the serial_info() call.

A limitation still exists in that the size is not available when OF_LIVE
is enabled, so take account of that in the tests.

dm: core: Support writing a 64-bit value

2023-10-06T18:38:13+00:00

Add support for writing a single 64-bit value into a property.

Repurpose the existing tests to handle this case too.

dm: core: Support writing a boolean

2023-10-06T18:38:13+00:00

Add functions to write a boolean property. This involves deleting it if
the value is false.

Add a new ofnode_has_property() as well. Add a comment about the behaviour
of of_read_property() when the property value is empty.

dm: core: Add a way to convert a devicetree to a dtb

2023-10-06T18:38:13+00:00

Add a way to flatten a devicetree into binary form. For livetree this
involves generating the devicetree using fdt_property() and other calls.
For flattree it simply involves providing the buffer containing the tree.

dm: core: Add a way to copy a node

2023-10-06T18:38:12+00:00

Add a function to copy a node to another place under a new name. This is
useful at least for testing, since copying a test node with existing
properties is easier than writing the code to generate it all afresh.
