#                       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
#------------------------------------------------------------------------------

# 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

# against.

# Enable support for a subset of the C++ language. This option increases code 
# footprint by adding support for C++ constructors. Certain features, such as 
# multiple inheritance and exceptions are not supported. If false, adds 
# -DALT_NO_C_PLUS_PLUS to ALT_CPPFLAGS in public.mk, and reduces code 
# footprint. none

# When your application exits, close file descriptors, call C++ destructors,

# Causes code to be compiled with gprof profiling enabled and the application 
# ELF to be linked with the GPROF library. If true, adds -DALT_PROVIDE_GMON to 
# ALT_CPPFLAGS and -pg to ALT_CFLAGS in public.mk. none 
# setting hal.enable_gprof is false

# 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

# 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 
# exception if a stack collision occurs with the heap or statically allocated

# ALT_CPPFLAGS in 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 
# loops. If true, adds -DALT_SIM_OPTIMIZE to ALT_CPPFLAGS in public.mk. When 
# this setting is true, the BSP shouldn't be used to build applications that 
# 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, 
# and buffered I/O. The small C library is not compatible with Micrium 
# 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 
# hardware design on the target. If false, adds --accept-bad-sysid to 
# SOPC_SYSID_FLAG in public.mk. none

# C/C++ compiler to generate (do not generate) GP-relative accesses. 'none'
