The board relies on the concept of Mips generic boards, and utilizes generic board framework for build and device organization. The Ranchu board is intended to be used by Android emulator.The name "Ranchu" originates from Android development community. "Goldfish" and "Ranchu" are names for two generations of virtual boards used by Android emulator. "Ranchu" is a newer one among the two, and this series deals with Ranchu. However, for historical reasons, some file, device, and variable names in this series still contain the word "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. Checkpatch script outputs a small number of warnings if applied to this series. We did not correct the code, since we think the code is correct for those particular cases of checkpatch warnings.
