Sat Oct 8 14:33:29 CEST 2011
The flea3 board is a custom board by CarMediaLab used
in automotive.
Network (FEC), NOR, NAND and SPI are supported.
Signed-off-by: Stefano Babic <sbabic at denx.de>
---
Changes since V4:
- boards.cfg maust have a new entry only for flea3 (Fabio Estevam)
Changes since V3:
- fix checkpatch warnings (Wolfgang Denk)
Changes since V2:
- put the board into manufacturer's directory (CarMediaLab)
Changes since V1:
- add missing entry in MAINTAINERS (F. Estevam)
