Add support for the base Device Tree for Imagination Technologies'
Pistachio SoC.
This commit supports the following peripherals:
* Clocks
* Pinctrl and GPIO
* UART
* SPI
* I2C
* PWM
* ADC
* Watchdog
* Ethernet
* MMC
* DMA engine
* Crypto
* I2S
* SPDIF
* Internal DAC
* Timer
* USB
* IR
* Interrupt Controller

* [PATCH 2/2] MIPS: DTS: img: add device tree for Marduk board
@ 2016-10-06 12:31 ` Rahul Bedarkar
0 siblings, 0 replies; 13+ messages in thread
From: Rahul Bedarkar @ 2016-10-06 12:31 UTC (permalink / raw)
To: Ralf Baechle, Rob Herring, Mark Rutland, James Hartley
Cc: linux-mips, devicetree, linux-kernel, Rahul Bedarkar
Add support for Imagination Technologies' Marduk board which is based
on Pistachio SoC. It is also known as Creator Ci40. Marduk is legacy
name and will be there for decades.
Documentation for this board can be found on
https://docs.creatordev.io/ci40/
This patch adds initial support for board with following peripherals:
* PWM based heartbeat LED
* GPIO based buttons
* SPI NOR flash on SPI1
* UART0 and UART1
* SD card
* Ethernet
* USB
* PWM
* ADC
* I2C

* [PATCH 2/2] MIPS: DTS: img: add device tree for Marduk board
@ 2016-10-06 12:31 ` Rahul Bedarkar

Add support for Imagination Technologies' Marduk board which is based
on Pistachio SoC. It is also known as Creator Ci40. Marduk is legacy
name and will be there for decades.
Documentation for this board can be found on
https://docs.creatordev.io/ci40/
This patch adds initial support for board with following peripherals:
* PWM based heartbeat LED
* GPIO based buttons
* SPI NOR flash on SPI1
* UART0 and UART1
* SD card
* Ethernet
* USB
* PWM
* ADC
* I2C

Bootloader (uboot) can override or fixup memory node. But with version
of bootloader I tested with, base address is hardcoded to 0 and only
size may get changed. But since booloader can override or fixup memory
node, I assume we don't add unit address in this case.

I now realized that size is incorrectly specified in memory node. It
should be 256MB and not 128MB. I will fix this in v2.
Thanks,
Rahul

This is board dependent, and since you have already explained that the boot loader is expected to configure this, I would recommend leaving it at 128MB (which I believe is the size of the smallest DDR part in use on existing boards). This would mean that if for some reason the boot loader did not adjust the settings, it would still boot on all currently known boards.

So it seems the 128MB boards are not CI40 based, so since this dts is CI40 specific, it's fine to have 256MB.
