Hi all,
This series updated u-boot-test-hooks to adopt QEMU 9.0.
It also introduced 3 new boards: qemu-arm64be, qemu-xtensa-dc233c and
qemu-loongarch64.
This is required for CI changes.
I'm going to respin other series later to utilise those new hooks.

`b4` is a commandline tool to make patch-based development easier[1]
Provide a .b4-config file to match U-Boot's patch preference so it will
be easier for people to use b4 with U-Boot development.

Jiaxun Yang (13):
pci: xilinx: Handle size of ecam region properly
pci: auto: Reduce
Probe size of ecam from devicetree properly and cap accessible
bus number accorading to ecam region size to ensure we don't go
beyond hardware address space.
Also disable all interrupts to ensure errors are handled silently.

Boston has a very limited memory range for PCI controllers, where
1MB can't easily fit into it.
Make alignment boundary of PCI memory resource allocation a Kconfig
option and default to 0x1 for boston.

For MIPS we are always looking gd->dram in virtual address so
PCI_MAP_SYSTEM_MEMORY should always be enabled.
If in future we ever want to make it physical we have to set
ARCH_MAP_SYSMEM.

higher bits are written into registers/sg properly.
Use memalign for allocating aligned buffer in dwc_ahsata so we
don't have to do our own alignment in driver.

Remove hard dependencies to arch headers, get clock from clk
subsystem if arch clock function is not available, align
compatible strings with devicetree binding.
No functional change on existing platforms, just get it build

When bootph-all is enabled for a syscon driver, the device
may leave unprobed when syscon_get_regmap is called by another
driver.
Perform device_probe in syscon_get_regmap, there is no side
affect as device_probe will return 0 quickly for an activated
device.

In upstream devicetree, clk_boston is a child of syscon node
and there is no "regmap" property for clk_boston node.
Try to check parent device first to look for syscon.
