treewide: move bi_dram[] from bd to gd

2026-06-25T00:13:24Z

Currently, the bi_dram[] information is stored in the board info structure (bd). Because bd is only valid after reserve_board(), dram_init_banksize() must be called late in the initialization process. This limitation is problematic, as it forces us to rely on a variety of bespoke functions to determine board RAM, bank memory sizes, and other early setup requirements. By moving bi_dram[] into the global data (gd), we can run it earlier. This is particularly convenient since boards define their own dram_init_banksize() routines, which do not always rely on parsing Device Tree (DT) memory nodes. Additionally, U-Boot defaults to relocating to the top of the first memory bank. While boards currently use custom functions to override this behavior, having the DRAM bank information available earlier in gd makes relocating to a different bank trivial and standardizes the process.

pci: correct PCI device enumeration to include all functions on device 0

2026-04-27T17:11:08Z

Currently the implementation does not just skip all devices beside device 0, it also skips all functions (besides 0) on device 0. This broke basically all AMD platforms, since they have a lot of internal SOC devices behind these functions. This was detected, because the XHCI controller and therefore the USB devices were not found by u-boot on AMD/crater platform. PCI_MASK_BUS() returns both device and function bits, so it skips any bdf where either device > 0 or function > 0. Using PCI_DEV() extracts only the device number, matching the intent in only_one_child(). It therefore now checks all functions on device 0 (Linux does the same). I build tested u-boot as coreboot payload and run it on a recent x86 AMD platform. Devices like the XHCI controller are now found again.

pci: skip unnecessary PCIe scanning

Use the same mechanism as the Linux kernel to skip unnecessary (and in the case of the J722S, errant) scanning of direct children of root ports, downstream ports or bridges.

pci: Assign a default value on reads on error

2025-07-14T21:16:48Z

Many callers of PCI read functions do not check the return value for error before using the variable that should contain the value read were there not to be an error. However in the error case this variable is never assigned to and so will contain uninitialised data. To provide some certainty as to behaviour in the error case assign a default value of all bits set. This issue found by Smatch. Signed-off-by: Andrew Goodbody

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

2023-10-06T18:38:13Z

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. Signed-off-by: Simon Glass
