d024ba24ee MIPS: Add Mobileye EyeQ6Lplus evaluation board dts
Add the device tree of the evaluation board of the EyeQ6Lplus SoC.

The board comes with 2GB of RAM and an SPI NAND connected to the octoSPI
controller The UART of the SoC is used as the serial console.

361600d16e MIPS: Add Mobileye EyeQ6Lplus SoC dtsi
Add the device tree include files for the EyeQ6Lplus system on chip
from Mobileye.

Those files provide the initial support of the SoC:
* The I6500 CPU and GIC interrupt controller.
* The OLB ("Other Logic Block") providing clocks, resets and pin controls.
* One UART.
* One GPIO controller.
* Two SPI controllers, one in host mode and one in target mode.
* One octoSPI flash controller.
* Two I2C controllers.

79b888ee4c MIPS: dts: loongson64g-package: Switch to Loongson UART driver
Loongson64g is Loongson 3A4000, whose UART controller is compatible with
Loongson 2K1500, which is NS16550A-compatible with an additional
fractional frequency divisor register.

Update the compatible strings to reflect this, so that 3A4000 can
benefit from the fractional frequency divisor provided by loongson-uart.
This is required on some devices, otherwise their UART can't work at
some high baud rates, e.g., 115200.

Tested on Loongson-LS3A4000-7A1000-NUC-SE with a 25MHz UART clock.
Without fractional frequency divisor, the actual baud rate was 111607
(25MHz / 16 / 14, measured value: 111545) and some USB-to-UART
converters couldn't work with it at all. With fractional frequency
divisor, the measured baud rate becomes 115207, which is quite accurate.

MIPS: tools: relocs: Ship a definition of R_MIPS_PC32
R_MIPS_PC32 is a GNU extension, its definition is available in glibc
only since 2.39 (released in 2024), and not available in musl libc yet.
Provide our own definition for R_MIPS_PC32 and use it if necessary to
fix relocs tool building on musl and older glibc systems.

e4ec36bf7b MIPS: Loongson64: dts: fix phy-related definition of LS7A GMAC
Currently the LS7A GMAC device tree node lacks a proper phy-handle
property pointing to the PHY node.

In addition, the phy-mode property specifies "rgmii" without any
internal delay information, which means the board trace needs to add 2ns
delay to the RGMII data lines; but that isn't known to happen on any
Loongson board. The ACPI-based initialization codepath, which is used on
LoongArch-based 3A5000 + 7A1000 hardwares, specifies "rgmii-id" phy
mode, which should be the one we are using.

Add the lacking phy-handle property and set proper phy-mode.

Tested on a LS3A4000_7A1000_NUC_BOARD_V2.1 board with YT8521S PHY.

mips: Add support for PC32 relocations in vmlinux
MIPS supports PC32 relocations like most other architectures, which will
be used by kallsyms to make its symbol references visible to the linker.

Given that these are place-relative, they can be ignored by the 'relocs'
tool, just like other PC type relocations.

4f0b3cd7b6 MIPS: dts: Always descend vendor subdirectories
Commit 41528ba6af ("MIPS: DTS: Only build subdir of current platform")
broke building of all DTBs when CONFIG_OF_ALL_DTBS is enabled unless all
the various kconfig options were also enabled. The only effect that commit
had was getting rid of some harmless build lines such as:

      AR      arch/mips/boot/dts/mti/built-in.a

Those lines were part of the built-in DTB support. Since commit
04e4ec98e4 ("MIPS: migrate to generic rule for built-in DTBs"), how the
built-in DTBs are handled has changed and those lines are no longer
generated, so revert to the prior behavior.

c1dbf4c8c2 MIPS: mobileye: eyeq5: add 5 I2C controller nodes
Add the SoC I2C controller nodes to the platform devicetree. Use a
default bus frequency of 400kHz. They are AMBA devices that are matched
on PeriphID.

Set transfer timeout to 10ms instead of Linux's default of 200ms.

The RTL9300 has a block of GPIOs included in the SoC. Add these to the

This is taken from openwrt[1] the differences are removing the
unnecessary second cell from the interrupt and removing the -controller

6d48ad0407 MIPS: Ignore relocs against __ex_table for relocatable kernel
Since commit 6f2c2f93a1 ("scripts/sorttable: Remove unneeded
Elf_Rel"), sorttable no longer clears relocs against __ex_table,
claiming "it was never used."  But in fact MIPS relocatable kernel had
been implicitly depending on this behavior, so after this commit the
MIPS relocatable kernel has started to spit oops like:

	CPU 1 Unable to handle kernel paging request at virtual address 000000fffbbdbff8, epc == ffffffff818f9a6c, ra == ffffffff813ad7d0
	... ...
	Call Trace:
	[<ffffffff818f9a6c>] __raw_copy_from_user+0x48/0x2fc
	[<ffffffff813ad7d0>] cp_statx+0x1a0/0x1e0

	[<ffffffff813ae670>] sys_statx+0xd8/0xf8
	[<ffffffff81156cc8>] syscall_common+0x34/0x58

So ignore those relocs on our own to fix the issue.
