SCTLR_EL2 is a 64-bit register [1]. Return its value as long (64 bit)
instead of int (32 bit) in get_sctlr() to make sure it's not trimmed.

The decision on whether HAB is enabled is solely based on the SEC_CONFIG
fuse. The HAB FIELD_RETURN feature is able to permanently disable HAB on
a CPU, after which it is able to boot unsigned firmware. U-Boot however
does not take into account the FIELD_RETURN mode, and refuses to boot
unsigned software when the feature is enabled.
Also take the FIELD_RETURN fuse into account when deciding whether HAB
is enabled. When The FIELD_RETURN fuse is blown, HAB is not enabled.
Tested on i.MX8M Mini, i.MX8M Plus, i.MX8M Nano and i.MX6ULL

Hi all,
This patch series aims to add DM support for the AEMIF controller that
can be found in the DaVinci SoCs.
This controller has already a driver used by the Keystone SoCs so I
add my work to it.
As we can now easily import Linux device-trees, I try to stick the
most I can to the Linux bindings of the AEMIF controller. To do so I add
an 'intermediate' driver called 'ti-aemif-cs'. It's in charge of
configuring timings for a given chip select of the AEMIF controller.

AEMIF controller is present on other SoCs than the Keystone ones.
Remove Keystone specificities from the driver to be able to use it from
other architectures.

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.

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.

Add support for Arm sbsa [1] v0.3+ that is supported by QEMU [2].
Unlike other Arm based platforms the machine only provides a minimal
FDT that contains number of CPUs, ammount of memory and machine-version.
The boot firmware has to provide ACPI tables to the OS.
Due to this design a full DTB is added here as well that allows U-Boot's
driver to properly function. The DTB is appended at the end of the U-Boot
image and will be merged with the QEMU provided DTB.
In addition provide documentation how to use, enable binman to fabricate both
ROMs that are required to boot and add ACPI tables to make it full compatible
to the EDK2 reference implementation.
The board was tested using Fedora 40 Aarch64 Workstation. It's able
to boot from USB and AHCI or network.
Tested and found working:
- serial
- PCI
- xHCI
- Bochs display
- AHCI
- network using e1000e
- CPU init

Add dedicated getter and setter for SCLK_UART0_PMU.
This allows the driver to correctly handle UART0 clocks, and thus
it fixes the issues with UART0 not working in case DEBUG_UART is
disabled.
Unlike other Rockchip SoCs, i.e. rk3399, in the PX30 the default
clock source for UART is GPLL, instead of external oscillator.
If the DEBUG_UART is enabled, the clock source is changed in
board_debug_uart_init function to 24Mhz oscillator, which also
matches the fallback value obtained from DT node.
In case the DEBUG_UART is disabled, the UART clock source remains
default, and the DM serial driver wrongly configures the baud rate,
resulting in broken communication.
By implementing the UART clock getter/setter, the serial driver
can probe the actual configuration and corectly configure itself.
The DEBUG_UART settings now should not affect it.
The driver supports GPLL and 24M oscillator. NPLL and USBPHY480M
sources, that are managed by CRU, are not yet handled, as likely
they won't be used in real scenarios.

MMU issues are some of the most frustrating to debug. To make this
slightly less unbearable, introduce a software pagetable walker for
ARMv8. This can be called to dump a pagetable with the default
formatter, or a custom callback can be provided to implement more
complicated parsing.
This can also be useful to dump the pagetable used by a previous
bootloader stage (by reading out the ttbr register).
Here is an example of the output when walking U-Boot's own memory map
on a Qualcomm RB3 board:
Walking pagetable at 000000017df90000, va_bits: 36. Using 3 levels

[0x17de00000 - 0x17dfa0000] | Pages | Normal | Inner-shareable
|
|
Add a basic software implementation of the ARM64 pagetable walker. This
can be used for debugging U-Boot's pagetable, as well as dumping the
pagetable from the previous bootloader stage if it used one (by reading
out the ttbr address).
One can either call dump_pagetable() to print the pagetable to the
console with the default formatter, or implement their own pagetable
handler using walke_pagetable() with a custom pte_walker_cb_t callback.
All of the added code is discarded when unused, hence there is no need
to add an additional Kconfig option for this.
