| # BSP "PUBLIC" MAKEFILE CONTENT | |
| # | |
| # This file is intended to be included in an application or library | |
| # Makefile that is using this BSP. You can create such a Makefile with | |
| # the nios2-app-generate-makefile or nios2-lib-generate-makefile | |
| # commands. | |
| # | |
| # The following variables must be defined before including this file: | |
| # | |
| # ALT_LIBRARY_ROOT_DIR | |
| # Contains the path to the BSP top-level (aka root) directory | |
| #------------------------------------------------------------------------------ | |
| #------------------------------------------------------------------------------ | |
| # PATHS | |

| # Path to the provided linker script. | |
| BSP_LINKER_SCRIPT := $(ALT_LIBRARY_ROOT_DIR)/linker.x | |
| # Include paths: | |
| # The path to root of all header files that a library wishes to make | |
| # available for an application's use is specified here. Note that this | |
| # may not be *all* folders within a hierarchy. For example, if it is | |
| # desired that the application developer type: | |
| # #include <sockets.h> | |
| # #include <ip/tcpip.h> | |
| # With files laid out like this: | |
| # <root of library>/inc/sockets.h | |
| # <root of library>/inc/ip/tcpip.h | |
| # | |
| # Then, only <root of library>/inc need be added to the list of include | |
| # directories. Alternatively, if you wish to be able to directly include | |
| # all files in a hierarchy, separate paths to each folder in that | |
| # hierarchy must be defined. | |
| # The following are the "base" set of include paths for a BSP. | |
| # These paths are appended to the list that individual software | |
| # components, drivers, etc., add in the generated portion of this | |
| # file (below). | |

| # Enables lightweight device driver API. This reduces code and data footprint | |
| # by removing the HAL layer that maps device names (e.g. /dev/uart0) to file | |
