AST2700 is the 8th generation of Integrated Remote Management
Processor introduced by ASPEED Technology Inc. It is a Board
Management Controller (BMC) SoC family with a dual-die architecture:
SoC0 ("CPU" die with four ARM Cortex-A35 application cores) and
SoC1 ("IO" die with peripherals) each SoC have its own SCU PLLs,
clock dividers and reset domains.

Add initial device tree support for the ASPEED AST27xx family, the
8th-generation Baseboard Management Controller (BMC) SoCs.
AST27xx SOC Family
- https://www.aspeedtech.com/server_ast2700/
- https://www.aspeedtech.com/server_ast2720/
- https://www.aspeedtech.com/server_ast2750/
The AST27xx features a dual-SoC architecture consisting of two ties,
referred to as SoC0 and SoC1 - interconnected through an internal
property bus. Both SoCs share the same address decoding scheme,
while each maintains independent clock and reset domains.
- SoC0 (CPU die): contains a dual-core Cortex-A35 cluster and two
Cortex-M4 cores, along with high-speed peripherals.
- SoC1 (I/O die): includes the BootMCU (responsible for system
boot) and its own clock/reset domains low-speed peripherals.
The device tree describes the SoC0 and SoC1 domains and their peripheral
layouts.

mach-axiado AX3005 SCM3005 board, a quad-core ARM Cortex-A53 (ARMv8/ARM64) platform."
Siu Ming Tong <[email protected]> says:
Patch 1 adds the device tree files: an SoC-level DTSI describing
GIC-v3, Cadence/Zynq UART, a fixed reference clock, and spin-table
secondary CPU boot, plus a board-level DTS setting the console to
uart3 at 115200 baud with 2 GB DRAM at 0x80000000.
Patch 2 adds mach-axiado to support Axiado SoC-based boards, Kconfig
plumbing (AXIADO_AX3005 and TARGET_SCM3005), defconfig, board source
with ft_board_setup() and a MAINTAINERS entry.

Add device tree source files for the Axiado AX3005 SCM3005 board.
The AX3005 is a quad-core 64-bit ARMv8 Cortex-A53 SoC.
The DTSI describes the SoC-level nodes: GIC-v3 interrupt controller,
Cadence/Zynq UART, fixed reference clock, and spin-table secondary
CPU boot. A /memreserve/ directive protects the spin-table release
address at 0x80002fa0 from being overwritten during boot.
The SCM3005 DTS sets the console to uart3 at 115200 baud and declares
2 GB of DRAM starting at 0x80000000.

Add board support for the Freebox Nodebox 10G based on the Marvell
Armada 8040 SoC. This board features:
- Quad-core ARMv8 AP806 with dual CP110 companions
- eMMC storage via Xenon SDHCI controller
- 1G SGMII Ethernet on CP0 lane 5
- I2C buses for peripheral access
- NS16550 UART console at 115200 baud
The implementation includes:
- Device tree for the Nodebox 10G hardware
- Dedicated board directory (board/freebox/nbx10g/)
- Board-specific Kconfig and defconfig
The U-Boot comphy bindings (phy-type/phy-speed) differ from the
mainline Linux PHY framework bindings used by phy-mvebu-cp110-comphy,
so U-Boot and the kernel each have their own device tree.

Add the Allied Telesis x220 board. There are a number of other variants
with the same CPU block that are sold under some different brand names
but the x220 was first.
The x220 uses the AlleyCat3 switch chip with integrated ARMv7 CPU.
Because of this it is reliant on a binary blob for the DDR training. In
upstream u-boot this is replaced by an empty file.

Caleb Ethridge <[email protected]> says:
This series performs a general cleanup of the default U-boot environment
for sc5xx boards, stemming from the decision to no longer store the
environment in the SPI flash. The environments for each board have been
edited to contain the minimum number of commands needed for all supported
boot modes to avoid confusion, and the default boot command synced to spi
for all boards that support it. The filesystem for the SPI flash has also
been changed from jffs2 to ubifs.
A bug with the Ethernet reset line on the sc594 has been fixed, and the
sc573 has been renamed from the EZKIT to the EZLITE to match the name of the
publically available board. EZKIT was only used internally before release.
Preliminary binman support for sc5xx boards has been removed as it was unused
and full support never added.

Add support for building U-Boot for Cortex-M33 RSIP core in Renesas
R-Car Gen5 R8A78000 X5H SoC. The main goal is to start U-Boot on the
Cortex-M33 RSIP core, which initializes the hardware and then starts
the Cortex-M33 SCP and Cortex-A720 cores which run the SCP firmware
and applications software respectively. The SCP is responsible for
platform resource management, and is used to start other CPU cores.
The Cortex-M33 build contains its own r8a78000_ironhide_cm33_defconfig
which configures the build for aarch32 instruction set compatible with
the ARMv8M core. The build also uses -cm33 DT and -u-boot.dtsi which
are derived from their non-CM33 counterparts, and add CM33 specifics.
The arch/arm/mach-renesas/u-boot-rsip.lds is derived from generic
arch/arm/cpu/u-boot.lds with adjustments to cater to the RSIP core,
those are entrypoint before vectors, __data_start/__data_end symbols
for data-only relocation, and placement of BSS into read-write SRAM
area.

Enable OF_UPSTREAM to use upstream Linux kernel DT source as a base

are not yet part of upstream Linux kernel DT in -u-boot.dtsi files
until they get replaced by upstream equivalents. Add renesas/ prefix
to the DEFAULT_DEVICE_TREE as part of the switch.
Unused i2c2..i2c8 nodes have been removed, and will become available
once upstream Linux kernel DT adds those nodes.
The DRAM_RSV_SIZE has been updated to cover first 518 MiB of DRAM,
which are reserved for firmware and other use.
Note that all DT parts in -u-boot.dtsi are not considered stable DT
bindings and may change before they land in Linux kernel and become
stable DT ABI.

The device tree on Apple silicon devices is passed from a previous
bootloader stage. The bootloader fills in dynamic information so
u-boot can not use its own device tree.
As documented in doc/board/apple/m1.rst it is possible to build boot
bundles (bootloader + device tree + gzipped u-boot binary). These are
useful for testing.
Instead of using u-boot's own device trees for M1 (t8103) devices use
upstream device trees from dts/upstream/src/arm64/apple. The u-boot
device trees have not seen updates since 2022. The upstream linux device
trees have feature parity for the M1 devices. In addition linux has
device trees for M1 Pro/Max/Ultra, M2 and M2 Pro/Max/Ultra devices.
Keep t8103-j274 as default device tree to avoid further updates.
