This series adds basic support for the Imagination Technologies Pistachio
SoC. Pistachio will boot using device-tree only. v4.0-rc1 already includes
support for several of the peripherals on Pistachio, including MMC, SPI,
I2C, DMA, watchdog timer, PWM, and IR. Clock and pinctrl support for
Pistachio is coming soon, as well as an initial device-tree and support
for USB and ethernet.
Patches 1 and 2 are cleanups in preparation for adding Pistachio support,
with patch 1 having been posted by Kevin late last year [1]. Patch 3
documents Pistachio's required device-tree properties/nodes and its boot
protocol. Patch 4 adds support for Pistachio itself and finally patch 5
adds a defconfig for Pistachio.
Boot tested on an IMG Pistachio BuB ("bring-up board") and build tested
for all other affected platforms. Based on v4.0-rc4. A tree with these
changes is available at [2].
Changes from v2:
- Addressed review comments from James
Changes from v1:
- Switched to MIPS UHI hand-off protocol
