Add basic Presidio G3 engineering board support
Signed-off-by: Alex Nemirovsky alex.nemirovsky@cortina-access.com
---
Changes in v4: - clean up presidio_asic.h per trini recommendations - use autogen savedefconfig instead of manual maintained file
Changes in v3: - fixed dts closing bracket indentation - presidio.h: remove deadcode from presidio.h - presidio.h: remove CA_REG_READ/CA_REG_WRITE wrapper macros - presidio.h: remove CA77xx define replace use CA common Kconfig SoC selection instead - select SOC_CA7774 via board's Kconfig - select BIT64 via board's Kconfig instead of presidio.h
Changes in v2: None
