MIPS: mobileye: Add EyeQ6H support

2024-06-11T08:15:50+00:00

EyeQ6H (or “High”) is an other SoC from Mobileye still based on the
MIPS I6500 architecture as the EyeQ5. The 2 clusters of this SoC
contains 4 cores which are capable of running 4 threads. Besides this,
it features multiple controllers such as the classic UART, high speed
I2C, SPI, as well as CAN-FD, PCIe Gen4, Octal/Quad SPI Flash
interface, Gigabit Ethernet, MIPI CSI-2, MIPI DSI, and eMMC 5.1. It
also includes a Hardware Security Module, Functional Safety Hardware,
and video encoders and more.

This commit provides the infrastructure to build a kernel running on
EyeQ6H SoC. For now the support is limited and only one CPU core is
running.

MIPS: generic: Allow generating FIT image for Marduk board

2021-08-12T14:01:49+00:00

Marduk is based on IMG pistachio SoC. The platform is using
MIPS UHI booting protocol and does have a proper devicetree
implement, thus it could be a part of generic kernel.

Add support for Realtek RTL838x/RTL839x switch SoCs

2021-02-04T19:17:54+00:00

The RTL838x/839x family of SoCs are Realtek switches with an embedded
MIPS core.

* RTL838x - 500MHz 4kce single core - 1Gbit ports and L2 features
* RTL839x - 700MHz 34Kc single core - 1Gbit ports and L2 features

These switches, depending on the exact part number, will have anywhere
between 8 and 52 ports. The MIPS core is wired to a switch cpu port which
has a tagging feature allowing us to make use of the DSA subsystem.
The SoCs are somewhat basic in certain areas, getting better with more
advanced features on newer series.

The switch functionality is MMIO-mapped via a large MFD region.

The SoCs have the following peripherals
* ethernet
* switch
* uart - ns16550a
* spi-flash interface
* gpio
* wdt
* led

The code was derived from various vendor SDKs based on Linux v2.6
kernels.

This patchset allows us to boot RTL838x/RTL839x units with basic support.
Most of the other drivers are already written and functional, and work to
get them upstream is already in progress.

MIPS: mscc: Prepare configuration to handle more SoCs

2020-11-12T22:31:47+00:00

Ocelot belongs to a family of SoC named the VCore III. In order to add
these new Soc, use the new symbol SOC_VCOREIII instead of a one
dedicated to Ocelot.

In order to avoid regression on driver building, the MSCC_OCELOT
configuration symbol is kept until the driver will be converted.

MIPS: DTS: Fix build errors used with various configs

2020-05-28T07:35:47+00:00

If CONFIG_MIPS_MALTA is not set but CONFIG_LEGACY_BOARD_SEAD3 is set,
the subdir arch/mips/boot/dts/mti will not be built, so the sead3.dts
which depends on CONFIG_LEGACY_BOARD_SEAD3 in this subdir is also not
built, and then there exists the following build error, fix it.

  LD      .tmp_vmlinux.kallsyms1

Makefile:1106: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1

Additionally, add CONFIG_FIT_IMAGE_FDT_BOSTON check for subdir img to
fix the following build error when CONFIG_MACH_PISTACHIO is not set but
CONFIG_FIT_IMAGE_FDT_BOSTON is set.
