2022-05-03pci: Check region ranges are addressableAndrew Scull
When parsing the `ranges` DT node, check that both extremes of the regions are addressable without overflow. This assumption can then be safely made when processing the regions. Signed-off-by: Andrew Scull <ascull@google.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2022-05-03pci: Fix use of flags in dm_pci_map_bar()Andrew Scull
The flags parameter of dm_pci_map_bar() is used for PCI region flags rather than memory mapping flags. Fix the type to match that of the region flags and stop using the regions flags as memory mapping flags. Signed-off-by: Andrew Scull <ascull@google.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2022-05-03virtio: pci: Read entire capability into memoryAndrew Scull
Read the virtio PCI capability out of the device configuration space to a struct rather than accessing fields directly from the configuration space as they are needed. This both makes access to the fields easier and avoids re-reading fields. Re-reading fields could result in time-of-check to time-of-use problems, should the value in the configuration space change. The range check of the `bar` field and the later call to `dm_pci_read_bar32()` is an example of where this could happen.

2022-05-02Merge branch '2022-05-02-add-verifying-program-loader'Tom Rini
To quote the author: U-Boot provides a verified-boot feature based around FIT, but there is no standard way of implementing it for a board. At present the various required pieces must be built up separately, to produce a working implementation. In particular, there is no built-in support for selecting A/B boot or recovery mode. This series introduces VPL, a verified program loader phase for U-Boot. Its purpose is to run the verified-boot process and decide which SPL binary should be run. It is critical that this decision happens before SPL runs, since SPL sets up SDRAM and we need to be able to update the SDRAM-init code in the field. Adding VPL into the boot flow provides a standard place to implement verified boot. This series includes the phase itself, some useful Kconfig options and a sandbox_vpl build for sandbox. No verfied-boot support is provided in this series. Most of the patches in this series are fixes and improvements to docs and various Kconfig conditions for SPL.

2022-05-02net: marvell: mvgbe: Set PHY page 0 before phy_connectTony Dinh
For most Kirkwood boards, the PHY page is already set to page 0 (in register 22) before phy_connect is invoked. But some board like the Zyxel NSA310S (which uses the network chip MV88E1318S), the PHY page is not set to page 0. There seems to be some bad data remained in register 22 when the uclass MVGBE about to invoke phy_connect(). This patch enables the uclass MVGBE to always set the PHY page to 0 before phy_connect.

To quote the author: The bootflow feature provide a built-in way for U-Boot to automatically boot an Operating System without custom scripting and other customisation. This is called 'standard boot' since it provides a standard way for U-Boot to boot a distro, without scripting. It introduces the following concepts: - bootdev - a device which can hold a distro - bootmeth - a method to scan a bootdev to find bootflows (owned by U-Boot) - bootflow - a description of how to boot (owned by the distro) This series provides an implementation of these, enabled to scan for bootflows from MMC, USB and Ethernet. It supports the existing distro boot as well as the EFI loader flow (bootefi/bootmgr). It works similiarly to the existing script-based approach, but is native to U-Boot. With this we can boot on a Raspberry Pi 3 with just one command: bootflow scan -lb which means to scan, listing (-l) each bootflow and trying to boot each one (-b). The final patch shows this. With a standard way to identify boot devices, booting become easier. It also should be possible to support U-Boot scripts, for backwards compatibility only. ...
