At present sandbox only supports a basic set of features. To help address this, a recent series added SPI and SPI flash support; this series expands the coverage further. Firstly SDL is used to provide LCD and audio support. Sandbox gains its own LCD driver which can display images, host a command line, etc. The audio support is basic and needs additional work, but it is a starting point. SDL also provides a keyboard emulation (using the Chrome OS EC code as a base). Secondly a TPM emulation is added. This does not include all features (the implementation is quite simplistic) but it is enough to do basic secure boot operations. Finally, various pieces of useful infrastructure are adding, including: - loading and saving of the emulated SDRAM to permit test runs to carry over state - loading and saving of general sandbox state (for example a driver can save its stage and reload it on the next run) - support for using bootm to load a kernel - providing a device tree for use by sandbox - block device emulation using host files - a means to jump to another U-Boot while preserving state (useful for test environments which want to run a series of tests with script-selectable state) - allowing the console to be active on start-up so that errors are not silent supressed The block device emulation provides access to filesystems from sandbox which should make it possible to write comprehensive filesystem tests. Major functions which still remain without sandbox support are I2C, networking and USB.
