| Native Execution of U-Boot |
| ========================== |
| |
| The 'sandbox' architecture is designed to allow U-Boot to run under Linux on |
| almost any hardware. To achieve this it builds U-Boot (so far as possible) |
| as a normal C application with a main() and normal C libraries. |
| |
| All of U-Boot's architecture-specific code therefore cannot be built as part |
| of the sandbox U-Boot. The purpose of running U-Boot under Linux is to test |
| all the generic code, not specific to any one architecture. The idea is to |
| create unit tests which we can run to test this upper level code. |
| |
| CONFIG_SANDBOX is defined when building a native board. |
| |
| The chosen vendor and board names are also 'sandbox', so there is a single |
| board in board/sandbox/sandbox. |
| |
| CONFIG_SANDBOX_BIG_ENDIAN should be defined when running on big-endian |
| machines. |
| |
| Note that standalone/API support is not available at present. |
| |
| The serial driver is a very simple implementation which reads and writes to |
| the console. It does not set the terminal into raw mode, so cursor keys and |
| history will not work yet. |

| Tests |

| So far we have no tests, but when we do these will be documented here. |
