This file holds the board info structure. We need this to be generic for the unified board series, so create a structure which contains the basic fields required by the main architectures.
Signed-off-by: Simon Glass sjg@chromium.org --- Changes in v6: - Add bi_ip_addr field back into struct bd_info
Changes in v5: - Use unsigned int for baud_rate - Remove bi_ip_addr field from struct bd_info
Changes in v4: - Add three more fields required for ARM
Changes in v3: None Changes in v2: None
