Rasmus VillemoesandFabio Estevam bfbbd8472e imx: hab: fix size of IVT+CSF blob tacked on to u-boot.itb
Loading flash.bin using uuu fails when flash.bin does not have the
right size.

When flash.bin is loaded from some storage medium (sd card/emmc), SPL
just loads some random garbage bytes from beyond what has been
populated when flash.bin was written, but when loaded via uuu, SPL
hangs waiting for the host to send the expected number of bytes. Which
is (size of FIT image aligned to 0x1000)+CONFIG_CSF_SIZE. The
alignment to 0x1000 is already done and is necessary in all cases
because that's the exact expected location of the 32 byte IVT
header. But the IVT+CSF blob tacked onto the end must be a total of
CONFIG_CSF_SIZE.

This is exactly the same fix as 89f19f45d6, except that this time
around I don't know how to cleanly get CONFIG_CSF_SIZE.

Tom Rini 1466ff7d83 Merge patch series "boards: siemens: iot2050: SM variant, sysinfo support, fixes & cleanups"
Jan Kiszka <jan.kiszka@siemens.com> says:

This adds support for the new IOT2050 SM variant, introduces a sysinfo
driver which also permits SMBIOS support and switches the board to
OF_UPSTREAM. There are some further fixes for the boards included as well.

Not yet included is configuration support for DMA isolation via the PVU as
this depends on not yet merged DT bindings and another overlay.

[trini: This is just the first 10 patches in the series for now]

Baocheng SuandTom Rini 3acd534b73 board: iot2050: Support new IOT2050-SM variant
Main differences between the new variant and Advanced PG2:

1. Arduino interface is removed. Instead, an new ASIC is added for
   communicating with PLC 1200 signal modules.
2. USB 3.0 type A connector is removed, only USB 2.0 type A connector is
   available.
3. DP interface is tailored down. Instead, to communicate with the
   PLC 1200 signal modules, a USB 3.0 type B connector is added but the
   signal is not USB.
4. DDR size is increased to 4 GB.
5. Two sensors are added, one tilt sensor and one light sensor.

Conor DooleyandLeo Yu-Chi Liang 239e470509 riscv: dts: mpfs: migrate to OF_UPSTREAM
The U-Boot copy of the mpfs devicetree has, in general, been neglected
somewhat in comparison to the one in Linux. Moving to OF_UPSTREAM to
keep both in sync should serve to eliminate that discrepancy.

Additionally, moving to OF_UPSTREAM will let U-Boot automatically pick
up the devicetree rework that is in progress at [1].

Conor DooleyandLeo Yu-Chi Liang 084367be4d clk: microchip: mpfs: support new syscon based devicetree configuration
Why get a devicetree description wrong once when you can get it wrong
twice? The original mistake, which the driver supports was failing to
describe the main PLL that the "cfg" and "periph" clocks parented by.
The second mistake was describing the "cfg" and "periph" clocks a
reg region within the clock controller, rather as two registers within
a syscon region that also contains pinctrl, interrupt muxing controls
and other functions.

Make up for lost time and describe these regions as they should have
been originally, preserving support for the existing two configurations
for the sake of existing systems with firmware-provided devicetrees.

Since now we only have M.2 variant consuming the overlay, it may not
have immediate effect for other variant, however this makes the future

Tom Rini 2800aecce0 Merge patch series "Implement ACPI on aarch64"
Patrick Rudolph <patrick.rudolph@9elements.com> says:

Based on the existing work done by Simon Glass this series adds
support for booting aarch64 devices using ACPI only.
As first target QEMU SBSA support is added, which relies on ACPI
only to boot an OS. As secondary target the Raspberry Pi4 was used,
which is broadly available and allows easy testing of the proposed
solution.

The series is split into ACPI cleanups and code movements, adding
Arm specific ACPI tables and finally SoC and mainboard related
changes to boot a Linux on the QEMU SBSA and RPi4. Currently only the
mandatory ACPI tables are supported, allowing to boot into Linux
without errors.

The QEMU SBSA support is feature complete and provides the same
functionality as the EDK2 implementation.

The changes were tested on real hardware as well on QEMU v9.0:

qemu-system-aarch64 -machine sbsa-ref -nographic -cpu cortex-a57 \
                    -pflash secure-world.rom \
                    -pflash unsecure-world.rom

qemu-system-aarch64 -machine raspi4b -kernel u-boot.bin -cpu cortex-a72 \
-smp 4 -m 2G -drive file=raspbian.img,format=raw,index=0 \
-dtb bcm2711-rpi-4-b.dtb -nographic

Tested against FWTS V24.03.00.

Known issues:
- The QEMU rpi4 support is currently limited as it doesn't emulate PCI,
  USB or ethernet devices!
- The SMP bringup doesn't work on RPi4, but works in QEMU (Possibly
  cache related).
- PCI on RPI4 isn't working on real hardware since the pcie_brcmstb
  Linux kernel module doesn't support ACPI yet.

Patrick RudolphandTom Rini 3cc4123ed5 arm: mach-bcm283x: Enable ARMV8_MULTIENTRY
On FDT platforms the APs are brought out of reset using the spin-table
as defined in the DT. On ACPI enabled platforms there's no FDT, thus
enable the ARMV8_MULTIENTRY and BLOBLIST to use the ACPI parking
protocol instead.

TEST: - APs enter Linux when run on qemu-system-aarch64 -machine raspi4b
      -	APs on real hardware do not enter Linux, but continue spinning in
        their ACPI parking protocol spinloop. To be investigated.

Patrick RudolphandTom Rini ceff6f478f arm: mach-bcm283x: Add ARMV8_MULTIENTRY support
When ACPI is enabled over FDT the APs cannot be brought out of reset
by the OS using the "FDT spin-table" mechanism, as no FDT is provided
to the OS. The APs must be released out of reset in u-boot and then
brought up in an ACPI compliant fashion.

When ARMV8_MULTIENTRY is specified, the APs are released from reset
and will enter U-Boot after it has been relocated as well.

By default ARMV8_MULTIENTRY is not selected, keeping existing behaviour.

TEST: All APs enter U-Boot when run on qemu-system-aarch64 and on
      real hardware.

Patrick RudolphandTom Rini 92e02b01ec armv8: cpu: Enable ACPI parking protocol
Update the generic entry point code to support the ACPI parking protocol.
The ACPI parking protocol can be used when PSCI is not available to bring
up secondary CPU cores.

When enabled secondary CPUs will enter U-Boot proper and spin in their own
4KiB reserved memory page, which also acts as mailbox with the OS to
release the CPU.

Patrick RudolphandTom Rini 34bfe8eff8 arm: cpu: Add ACPI parking protocol support
On Arm platforms that use ACPI they cannot rely on the "spin-table"
CPU bringup usually defined in the FDT. Thus implement the
'ACPI Multi-processor Startup for ARM Platforms', also referred to as
'ACPI parking protocol'.

The ACPI parking protocol works similar to the spin-table mechanism, but
the specification also covers lots of shortcomings of the spin-table
implementations.

Every CPU defined in the ACPI MADT table has it's own 4K page where the
spinloop code and the OS mailbox resides. When selected the U-Boot board
code must make sure that the secondary CPUs enter u-boot after relocation
as well, so that they can enter the spinloop code residing in the ACPI
parking protocol pages.

The OS will then write to the mailbox and generate an IPI to release the
CPUs from the spinloop code.

For now it's only implemented on ARMv8, but can easily be extended to
other platforms, like ARMv7.
