With printch() the console messages are sent out one character at a time which is agonizingly slow especially with semihosting as the whole trap intercept, remote byte access, and system resume danse is performed for every single character across a relatively slow remote debug connection. Let's use printascii() to send a whole string at once. This is also going to be more efficient, albeit to a quite lesser extent, with serial ports as well.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
