Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

cmd: Convert existing long help messages to the new macro

2023-10-16T14:24:58+00:00

- Generally we just drop the #ifdef CONFIG_SYS_LONGHELP and endif lines
  and use U_BOOT_LONGHELP to declare the same variable name as before
- In a few places, either rename the variable to follow convention or
  introduce the variable as it was being done inline before.

pci: Add checks to prevent config space overflow

2022-08-26T18:59:21+00:00

PCIe config space has address range 0-4095. So do not allow reading from
addresses outside of this range. Lot of U-Boot drivers do not expect that
passed value is not in this range. PCI DM read function is extended to
fill read value to all ones or zeros when it fails as U-Boot callers
ignores return value.

Calling U-Boot command 'pci display.b 0.0.0 0 0x2000' now stops printing
config space at the end (before 0x1000 address).

pci: Extend 'pci' command with bus option '*'

2022-01-28T22:58:41+00:00

Allow to call 'pci' and 'pci regions' commands with bus option '*' which
cause pci to process all buses.

PCIe is point-to-point HW and so on each bus is maximally one physical
device. Therefore for PCIe it is common to have multiple buses.

This change allows to easily print all available PCIe devices in system.

Make '*' as default option when no bus argument is specified.

pci: Extend 'pci regions' command with bus number

2022-01-28T22:58:41+00:00

'pci regions' currently prints only region information from bus 0 which
belongs to controller 0. Parser for 'pci regions' cmdline currently ignores
any additional arguments and so U-Boot always uses bus 0.

Regions are stored in controller (not on the bus) and therefore to retrieve
controller from the bus, it is needed to call pci_get_controller() which
returns root bus. Because bus 0 is root bus, current code worked fine for
controller 0.

Extend cmdline parser for 'pci regions' to allows specifying bus number,
extend pci_show_regions() code to accept also non-zero bus number and
print bus ranges for which is regions configuration assigned.
