* sandbox: Fix building with LLVMTom Rini2016-03-08-0/+6
| | | | | | | | | | | | - The macro __BIGGEST_ALIGNMENT__ is gcc-specific. If it is not defined we'll just assume 16. This is correct for at least the common cases and LLVM does not provide an equivalent macro. - When linking U-Boot we're passing -T to the linker, and while gcc will just pass this along with LLVM we need to be specific.

* usb: sandbox: Add a USB emulation driverSimon Glass2015-11-19-0/+2
| | | | | | | | | Add a simple USB keyboard driver for sandbox. It provides a function to 'load' it with input data, which it will then stream through to the normal U-Boot input subsystem. When the input data is exhausted, the keyboard stops providing data. Signed-off-by: Simon Glass <sjg@chromium.org>

* sandbox: Don't try distro_bootcmd by defaultSjoerd Simons2015-05-06-0/+1
| | | | | | | | | | | | For the distro_bootcmds to succeed on the sandbox a bit of setup is required (e.g. network configured or host image bound), so running them by default isn't that useful. Add a -b/--boot command to the sandbox binary, which triggers the distro_bootcmds to run after the other command-line commands.

| | | | | | | | | | | | Add a sandbox I2C emulation device which emulates a real-time clock. The clock works off an offset from the current system time, and supports setting and getting the clock, as well as access to byte-width regisers in the RTC.

* sandbox: eth: Add support for using the 'lo' interfaceJoe Hershberger2015-04-18-1/+9
| | | | | | | | | | | | | | | The 'lo' interface on Linux doesn't support thinks like ARP or link-layer access like we use to talk to a normal network interface. A higher-level network API must be used to access localhost. As written, this interface is limited to not supporting ICMP since the API doesn't allow the socket to be opened for all IP traffic and be able to receive at the same time. UDP is far more useful to test with, so it was selected over ICMP. Ping won't work, but things like TFTP should work.

* sandbox: Add options to clean up temporary filesSimon Glass2014-03-17-1/+2
| | | | | | | | | | | | | | | When jumping from one sandbox U-Boot to another in sandbox, the RAM buffer is preserved in the jump by using a temporary file. Add an option to tell the receiving U-Boot to remove this file when it is no longer needed. Similarly the old U-Boot image is left behind in this case. We cannot delete it immediately since gdb cannot then find its debug symbols. Delete it just before exiting. Together these changes ensure that temporary files are removed both for memory and U-Boot.

* sandbox: Add SDL library for LCD, keyboard, audioSimon Glass2014-03-17-0/+118
| | | | | | | | | | | | | | | | | SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox. This significantly expands the testing that is possible with sandbox. Add a basic SDL library which we will use in future commits.
