# 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).

# Here we provide a path to "our self" for the application to construct a
# "-L <path to BSP>" out of. This should contain a list of directories,
# relative to the library root, of all directories with .a files to link
# against.

# MANAGED CONTENT
#
# All content between the lines "START MANAGED" and "END MANAGED" below is
# generated based on variables in the BSP settings file when the

# information pertaining to the build process, it is recomended that you
# utilize the BSP settings mechanism to do so.

# Enable support for a subset of the C++ language. This option increases code

# Causes code to be compiled with gprof profiling enabled and the application

# 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
# descriptors. Instead, driver routines are called directly. The open(),
# close(), and lseek() routines will always fail if called. The read(),
# write(), fstat(), ioctl(), and isatty() routines only work for the stdio
# devices. If true, adds -DALT_USE_DIRECT_DRIVERS to ALT_CPPFLAGS in public.mk.
# The Altera Host and read-only ZIP file systems can't be used if

# setting hal.enable_lightweight_device_driver_api is false
# Adds code to emulate multiply and divide instructions in case they are

# Certain drivers are compiled with reduced functionality to reduce code

# operation. CAUTION: Several device drivers are disabled entirely. These
# include the altera_avalon_cfi_flash, altera_avalon_epcs_flash_controller, and
# altera_avalon_lcd_16207 drivers. This can result in certain API (HAL flash
# access routines) to fail. You can define a symbol provided by each driver to
# prevent it from being removed. If true, adds -DALT_USE_SMALL_DRIVERS to
# ALT_CPPFLAGS in public.mk. none
# setting hal.enable_reduced_device_drivers is false
# Turns on HAL runtime stack checking feature. Enabling this setting causes
# additional code to be placed into each subroutine call to generate an

# public.mk. none
# setting hal.enable_runtime_stack_checking is false
# The BSP is compiled with optimizations to speedup HDL simulation such as
# initializing the cache, clearing the .bss section, and skipping long delay

# are expected to run real hardware.
# setting hal.enable_sim_optimize is false
# Causes the small newlib (C library) to be used. This reduces code and data
# footprint at the expense of reduced functionality. Several newlib features
# are removed such as floating-point support in printf(), stdin input routines,

# MicroC/OS-II. If true, adds -msmallc to ALT_LDFLAGS in public.mk. none
# setting hal.enable_small_c_library is false
# Enable SOPC Builder System ID. If a System ID SOPC Builder component is
# connected to the CPU associated with this BSP, it will be enabled in the
# creation of command-line arguments to download an ELF to the target.
# Otherwise, system ID and timestamp values are left out of public.mk for
# application Makefile "download-elf" target definition. With the system ID
# check disabled, the Nios II EDS tools will not automatically ensure that the
# application .elf file (and BSP it is linked against) corresponds to the
