nios2: Makefile: optionally include SOC Makefile It may not necessarily exist. Change-Id: I5c79d7538edef78e38f7e05b004e69e0259dd079 Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>

nios2: basic build, non-functional Basic build framework for Nios2. Everything is stubbed out, we just want to have a build going so that we can start to parallelize implementation tasks. This patch is not intended to be functional, but should be able to produce a binary for all the nanokernel-based sanity checks.

nios2: move cflags hacks to main Nios2 Makefile These are for any Nios II at this stage of bring-up. Change-Id: Ie4d0c80df164f81f6615ac35d3f42235b04870f1 Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>

nios2: provide and include soc-specific headers BSP builds for Nios II generate a linker.h and system.h which reflects the configuration for that CPU. This can vary depending on how the CPU is wired up in QSYS, so it needs to be at the SOC level--we essentially treat any given CPU configuration as a SOC in Zephyr build terms. Include these files from <arch/cpu.h>. Change-Id: I12f76600107fec1a14a2f9cb82b0f55915ec03a6 Origin: Altera Quartus tools, machine generated Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>

# Nios II CPUs are configurable and we need to pull in the generated
# headers system.h and linker.h which specify what is enabled and where
# everything is.
nios2: add arch/nios2/soc/<soc>/include to linker include path Linker scripts for Nios II will also need these headers as it specifies the device's physical layout and various important vector addresses.

build: Introduce concept of SoC specific build flags Introduce a soc-cflags, soc-cxxflags, and soc-aflags as a means for SoC specific compiler flags to be set without manipulating Kbuild options directly.

nios2: generate kernel image in Intel HEX format Altera tools for creating .pof files for flashing onto their FPGAs require UFM data to be in this special format. Extend the current 'all' and 'zephyr' targets to additionally create this .hex file using objcopy, with the same exclusions as the existing rule for .bin files.

nios2: add flashing/debug scripts For the moment, NIOS2_CPU_SOF must be set with the path to the CPU configuration. We are checking with Altera on whether we can directly check in the binary to the source tree. These scripts depend on tools provided by the Altera Quartus Prime Lite Edition. This is available for free but requires registration on Altera's website to obtain. Change-Id: Ia6cb6c9e43c3e141807a887cb25c47b370a7d8e9 Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
