# Update the ARMv7-A ports from the generic ARMv7-A port, generating ports and
# examples from the common files. This is a port of update.ps1 beside it, which
# needs PowerShell and so could only be run on Windows. The two are kept
# equivalent: same cores, same compilers, same copy sets and the same patches.
#
# To update the ThreadX ports for the source tree:
# ./update.sh --port-sets tx --copy-common-files --copy-port-files \
# --copy-example --patch-files
#
# To update the ThreadX ports for the test tree:
# ./update.sh --port-sets tx --copy-common-files --copy-port-files \
# --copy-example --copy-validation-test --copy-regression-test \
# --patch-files
#
# --copy-example, --copy-validation-test and --copy-regression-test are
# accepted and ignored, exactly as in update.ps1, where they are declared as
# parameters but never consulted. They are kept so that both scripts take the
# same command line.
