# Purpose
|
|
#
|
|
# This script contains functions for shell scripts to
|
|
# help detect which project (Mbed TLS, TF-PSA-Crypto)
|
|
# or which Mbed TLS branch they are in.
|
|
|
|
# Project detection.
|
|
#
|
|
# Both Mbed TLS and TF-PSA-Cryto repos have a "scripts/project_name.txt" file
|
|
# which contains the name of the project. They are used in scripts to know in
|
|
# which project/folder we're in.
|
|
# This function accepts 2 parameters:
|
|
# - $1: boolean value which defines the behavior in case
|
|
# "scripts/project_name.txt" is not found:
|
|
# - 1: exit with error message
|
|
# - 0: simply return an error
|
|
# - $2: mandatory value which defined the root folder where to look for
|
|
# "scripts/project_name.txt".
