Subject: sandbox: show error if the device-tree cannot be loaded
X-Git-Url: http://git.dujemihanovic.xyz/%7B%7B%20%24style.Permalink%20%7D%7D?a=commitdiff_plain;h=66995164ddbedd3449673052a10fc35917bf3d78;p=u-boot.git

sandbox: show error if the device-tree cannot be loaded

U-Boot's printf() used before setting up U-Boot's serial driver does not
create any output. Use os_printf() for error messages related to loading
the device-tree.
