For sure this code is very low level, but I want to use some special IO features that Arm provided in a version of Newlib. Those special features are mainly used for Semihosting, or platform emulation when you emulate an Arm based hardware using the standard IO of the host to communicate.
For semihosting it is not necessary to include support in u-boot. The rvdebug application does that automatically regardless of the binary being aware of it or not. You need to alter the CPU/connection definition. It has an boolean called Semihosting, toggle this to True and all your output will appear in RVDS application.
