This enables generic board support so that x86 boards can define CONFIG_SYS_GENERIC_BOARD.
Signed-off-by: Simon Glass sjg@chromium.org --- Changes in v10: - Define __HAVE_ARCH_GENERIC_BOARD in the correct x86 patch
Changes in v9: - Use !CONFIG instead of nCONFIG
Changes in v8: None Changes in v7: None Changes in v6: None Changes in v5: - Avoid setting up gd on x86 as it is already done
Changes in v4: None Changes in v3: None Changes in v2: None
