mips: generic: add fdt fixup for Realtek reference board

2024-07-12T11:12:13+00:00

The bootloader used on the Realtek RTL9302C boards is an ancient vendor fork of U-Boot that doesn't understand device trees. So to run a modern kernel it is necessary use one of the APPENDED_DTB options. When appending the DTB the inintrd information, if present, needs to be inserted into the /chosen device tree node. The bootloader provides the initrd start/size via the firmware environment. Add a fdt fixup that will update the device tree with the initrd information.

MIPS: Share generic kernel code with other architecture

2024-02-20T12:36:25+00:00

Some architectures might seek to utilize a significant portion of the generic kernel code while maintaining independence from the generic kernel due to specific peculiarities. This patch allows for the reuse of core code, preventing unnecessary duplication.

MIPS: generic: Add support for Ingenic SoCs

2020-09-18T14:33:59+00:00

Add support for Ingenic SoCs in arch/mips/generic/. The Kconfig changes are here to ensure that it is possible to compile either a generic kernel that supports Ingenic SoCs, or a Ingenic-only kernel, both using the same code base, to avoid duplicated code.

MIPS: kexec: Use prepare method from Generic for UHI platforms

2018-09-22T17:32:34+00:00

Out-of-tree platforms may not be based on Generic as shown in customer communication. Share the prepare method with all using UHI boot protocol, and put into machine_kexec.c. The benefit is that, when having kexec_args related problems, developers will naturally look into machine_kexec.c, where "CONFIG_UHI_BOOT" will be found, prompting them to add "select UHI_BOOT" to the platform Kconfig. It would otherwise require a lot debugging or online searching to be aware that the solution is in Generic code.

MIPS: ranchu: Add Ranchu as a new generic-based board

2018-01-22T20:47:34+00:00

Provide amendments to the MIPS generic platform framework so that the new generic-based board Ranchu can be chosen to be built. The Ranchu board is intended to be used by Android emulator. The name "Ranchu" originates from Android development community. "Goldfish" and "Ranchu" are terms used for two generations of virtual boards used by Android emulator. The name "Ranchu" is a newer one among the two, and this patch deals with Ranchu. However, for historical reasons, some devices/drivers still contain the name "Goldfish". MIPS Ranchu machine includes a number of Goldfish devices. The support for Virtio devices is also included. Ranchu board supports up to 16 Virtio devices which can be attached using Virtio MMIO Bus. This is summarized in the following picture: ABUS ||----MIPS CPU || | IRQs ||----Goldfish PIC------------(32)-------- || | | | | | | | | | ||----Goldfish TTY------ | | | | | | | | || | | | | | | | | ||----Goldfish RTC-------- | | | | | | | || | | | | | | | ||----Goldfish FB----------- | | | | | | || | | | | | | ||----Goldfish Events--------- | | | | | || | | | | | ||----Goldfish Audio------------ | | | | || | | | | ||----Goldfish Battery------------ | | | || | | | ||----Android PIPE------------------ | | || | | ||----Virtio MMIO Bus | | || | | | | | || | | (virtio-block)--------- | || (16) | | || | (virtio-net)------------------ Device Tree is created on the QEMU side based on the information about devices IO map and IRQ numbers. Kernel will load this DTB using UHI boot protocol DTB handover mode.

Update MIPS email addresses

2017-11-03T16:02:30+00:00

MIPS will soon not be a part of Imagination Technologies, and as such many @imgtec.com email addresses will no longer be valid. This patch updates the addresses for those who: - Have 10 or more patches in mainline authored using an @imgtec.com email address, or any patches dated within the past year. - Are still with Imagination but leaving as part of the MIPS business unit, as determined from an internal email address list. - Haven't already updated their email address (ie. JamesH) or expressed a desire to be excluded (ie. Maciej). - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt & myself. New addresses are of the form firstname.lastname@mips.com, and all verified against an internal email address list. An entry is added to .mailmap for each person such that get_maintainer.pl will report the new addresses rather than @imgtec.com addresses which will soon be dead. Instances of the affected addresses throughout the tree are then mechanically replaced with the new @mips.com address.
