- * Semihosting configuration
- *
- * Copyright (c) 2015 Imagination Technologies
- * Copyright (c) 2019 Linaro Ltd
- *
- * This controls the configuration of semihosting for all guest
- * targets that support it. Architecture specific handling is handled
- * in target/HW/HW-semi.c
- *
- * Semihosting is sightly strange in that it is also supported by some
- * linux-user targets. However in that use case no configuration of
- * the outputs and command lines is supported.
- *
- * The config module is common to all softmmu targets however as vl.c
- * needs to link against the helpers.
