[PATCH 0/2] sandbox: error output

[Heinrich Schuchardt]

U-Boot's printf() cannot write to the console before the serial console
driver is set up. We need a function writing to the OS console.

Provide a new function os_printf() to print to the OS console.

Use the funciton to implement the error messages related to loading the
device-tree.

For sure there are more places where we need os_printf() instead of
printf() for error messages.

We also could use it to provide a debug console for the sandbox.

Heinrich Schuchardt (2):
  sandbox: add function os_printf()
  sandbox: show error if the device-tree cannot be loaded
