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.

core: fix doc comments of dev_read_addr*() and related functions

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

- The dev_read_addr_name*() family of functions has no "index" argument,
  doc comments should refer to "name"
- Specify the error return for several devfdt_get_addr*() functions

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.

core: fdtaddr: add devfdt_get_addr_size_index_ptr function

2023-05-06T09:28:18+00:00

Add devfdt_get_addr_size_index_ptr function with the same
functionality as devfdt_get_addr_size_index, but instead
a return pointer is given.

Correct Sphinx style comments in include/dm/fdtaddr.h
and add the devfdt API to the HTML documentation;
these functions are NOT compatible with live tree.

dm: core: Add a new API devfdt_get_addr_index_ptr()

2021-10-20T02:59:09+00:00

At present there is only devfdt_get_addr_ptr() which only returns
the first  pair in the 'reg' property. Add a new API
devfdt_get_addr_index_ptr() to return the indexed pointer.

dm: core: Use const device for the devfdt...() interface

2020-02-06T02:33:45+00:00

These functions do not modify the device so should use a const pointer to
it. Update the code accordingly.

dm: pci: Add a function to read a PCI BAR

2019-10-08T05:57:43+00:00

At present PCI address transaction is not supported so drivers must
manually read the correct BAR after reading the device tree info. The
ns16550 has a suitable implementation, so move this code into the core
DM support.

Note that there is no live-tree equivalent at present.

dm: core: add support for getting register address and size

2019-08-12T17:33:39+00:00

Current dev_read_*() API lacks support to get address and size
of a "reg" property by name or index. Add support for the same.

Livetree support has been added but not tested on real hardware.

The existing unit tests testing reading address from device-tree
have been updated to test address as well as size.
