arm64: dts: S32G3: Introduce device tree for S32G-VNP-RDB3

This commit adds device tree support for the NXP S32G3-based
S32G-VNP-RDB3 Board [1].

The S32G3 features an 8-core ARM Cortex-A53 based SoC developed by NXP.

The device tree files are derived from the official NXP downstream
Linux tree [2].

This addition encompasses a limited selection of peripherals that
are upstream-supported. Apart from the ARM System Modules
(GIC, Generic Timer, etc.), the following IPs have been validated:

    * UART: fsl-linflexuart
    * SDHC: fsl-imx-esdhc

Clock settings for the chip rely on ATF Firmware [3].
Pin control integration into the device tree is pending and currently
relies on Firmware/U-Boot settings [4].

These changes were validated using BSP39 Firmware/U-Boot from NXP [5].

The modifications enable booting the official Ubuntu 22.04 from NXP on
the RDB3 with default settings from the SD card and eMMC.

12 months agox86/efistub: Call mixed mode boot services on the firmware's stack

x86/efistub: Call mixed mode boot services on the firmware's stack

Normally, the EFI stub calls into the EFI boot services using the stack
that was live when the stub was entered. According to the UEFI spec,
this stack needs to be at least 128k in size - this might seem large but
all asynchronous processing and event handling in EFI runs from the same
stack and so quite a lot of space may be used in practice.

In mixed mode, the situation is a bit different: the bootloader calls
the 32-bit EFI stub entry point, which calls the decompressor's 32-bit
entry point, where the boot stack is set up, using a fixed allocation
of 16k. This stack is still in use when the EFI stub is started in
64-bit mode, and so all calls back into the EFI firmware will be using
the decompressor's limited boot stack.

Due to the placement of the boot stack right after the boot heap, any
stack overruns have gone unnoticed. However, commit

  5c4feadb0011983b ("x86/decompressor: Move global symbol references to C code")

moved the definition of the boot heap into C code, and now the boot
stack is placed right at the base of BSS, where any overruns will
corrupt the end of the .data section.

While it would be possible to work around this by increasing the size of
the boot stack, doing so would affect all x86 systems, and mixed mode
systems are a tiny (and shrinking) fraction of the x86 installed base.

So instead, record the firmware stack pointer value when entering from
the 32-bit firmware, and switch to this stack every time a EFI boot
service call is made.

is done as if 4-level paging is active, causing the system to crash on

While only a subset of the assignments that were moved need to be set
early, move all of the assignments back into check_la57_support() so that
these assignments aren't spread between two locations. Instead of just

commit 8bf26758ca96 ("x86/fpu: Add XFD state to fpstate") introduced a

On CPU hotplug MSR_IA32_XFD is reset to the init_fpstate.xfd, which

reset, which brings them out of sync.

As a consequence a subsequent xfd_update_state() might fail to update
the MSR which in turn can result in XRSTOR raising a #NM in kernel
space, which crashes the kernel.

To fix this, introduce xfd_set_state() to write xfd_state together
