cheatsheet.md: Re-write QEMU invocation example

The commandline provided had several issues:

* The -dtb option was redundant as we boot with the cuImage, and caused
  some kernel configuration to be skipped which in turn ended in a
  kernel panic
* -append argument was redundant with respect to the devicetree
* The file paths used typically required the user to change up out of
  the build directory after bitbaking obmc-phosphor-image

The patch addresses all of the above.

OpenBMC documentation

This repository contains documentation for OpenBMC as a whole. There may be component-specific documentation in the repository for each component.

OpenBMC Usage

These documents describe how to use OpenBMC, including using the programmatic interfaces to an OpenBMC system.

OpenBMC Development

These documents contain details on developing OpenBMC code itself

OpenBMC Goals

The OpenBMC project's aim is to create a highly extensible framework for BMC software and implement for data-center computer systems.

We have a few high-level objectives:

  • The OpenBMC framework must be extensible, easy to learn, and usable in a variety of programming languages.

  • Provide a REST API for external management, and allow for "pluggable" interfaces for other types of management interactions.

  • Provide a remote host console, accessible over the network

  • Persist network configuration settable from REST interface and host

  • Provide a robust solution for RTC management, exposed to the host.

  • Compatible with host firmware implementations for basic IPMI communication between host and BMC

  • Provide a flexible and hierarchical inventory tracking component

  • Maintain a sensor database and track thresholds
