Cleanup and preparation commit for linker script generator. Zephyr linker scripts provides start and end symbols for each section, and sometimes even size and LMA start symbols. Generally, start and end symbols uses the following pattern, as: Section name: foo Section start symbol: __foo_start Section end symbol: __foo_end However, this pattern is not followed consistently. To allow for linker script generation and ensure consistent naming of symbols then the following pattern is introduced consistently to allow for cleaner linker script generation. Section name: foo Section start symbol: __foo_start Section end symbol: __foo_end Section size symbol: __foo_size Section LMA start symbol: __foo_load_start This commit aligns the symbols for _ramfunc_ram/rom to other symbols and in such a way they follow consistent pattern which allows for linker script and scatter file generation. The symbols are named according to the section name they describe. Section name is `ramfunc` The following symbols are aligned in this commit: - _ramfunc_ram_start -> __ramfunc_start - _ramfunc_ram_end -> __ramfunc_end - _ramfunc_ram_size -> __ramfunc_size - _ramfunc_rom_start -> __ramfunc_load_start Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no> |

Title: Test to verify code execution from SRAM for XIP images (ARM Only)
Description:
This test verifies that we can define functions in SRAM (and
sucessfully execute them from SRAM) in ARM XIP images. It
also verifies that the .ramfunc section is accessible by
nPRIV code when building with support for user mode
(CONFIG_USERSPACE=y). Only for ARM Cortex-M targets.
---------------------------------------------------------------------------
Building and Running Project:
This project outputs to the console. It can be built and executed on QEMU as
follows:
ninja/make run
---------------------------------------------------------------------------
Troubleshooting:
Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:
ninja/make clean # discard results of previous builds
# but keep existing configuration info
or
ninja/make pristine # discard results of previous builds
# and restore pre-defined configuration info
---------------------------------------------------------------------------
