regression/change in master: formatting floats and doubles

[coderkalyan]

After updating to latest zephyr master, I noticed that I can't format float values with libc printf() or the logging API, while I used to be able to. I took a quick in the commit history, and there are some commits recently (in the last 2-3 weeks) regarding formatting in the libc implementation, but I could figure out what was the culprit.

Is there something I should be changing at build time, or a replacement format function, to achieve float formatting?

Add CONFIG_CBPRINTF_FP_SUPPORT=y to your prj.conf. This should be the default if you have CONFIG_FPU=y, but if you're doing software floating point it wouldn't be.
