Subject: [PATCH v2 2/9] metag: minimal TZ1090 (Comet) SoC infrastructure
Add really minimal support for Toumaz Xenif TZ1090 SoC (A.K.A. Comet).
This consists of minimal build infrastructure, device tree files, and a
defconfig based on meta2_defconfig.
This SoC contains a 2-threaded HTP (Meta 2) as the main application
processor, and is found in a number of development boards and digital
radios, such as the Minimorph Development Platform.
