[U-Boot] [PATCH 0/32] Add additional sandbox features and infrastructure

[Simon Glass]

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.
