Subject: [PATCH v5 4/6] arm64: Add initial support for Blaize BLZP1600 CB2
Add support for the Blaize CB2 development board based on
the BLZP1600 SoC. This consists of a Carrier-Board-2 and a
System-on-Module.
Both BLZP1600 SoM and CB2 are available as products.
CB2 (Pathfinder) has multiple peripherals like UART, I2C,
SPI, GPIO, CSI (camera), DSI (display), USB-3.0 and Ethernet.
Enable support for the Cryptocell, UART and I2C which are
already fully supported by the drivers.
The blaize-blzp1600.dtsi is the common part for the SoC,
blaize-blzp1600-som.dtsi is the common part for the SoM and
blaize-blzp1600-cb2.dts is the board specific file.
