Personally I wouldn't want another category (what you seem to mean by "section"). I also don't think this should be a code review site. However, asking for validation and advice on <i>small</i> and <i>specific</i> pieces of code is already on topic, if that code is somehow related to hardware. For example, this isn't the site to ask about a general C sorting function. But, you could ask people to look over a small section of code that sets up the UART on a particular microcontroller to make sure that specific hardware is managed correctly. An assembly routine to perform a floating point to fixed point conversion on a specific micro with limited instruction set might also be on topic. The main point is, that to be on topic here, there has to be some aspect of the code that is tied to hardware or the peculiarities of particular embedded processors.
