* sandbox: Add LCD driverSimon Glass2014-03-17-4/+150
| | | | | | | | | | | | | Add a simple LCD driver which uses SDL to display the image. We update the image regularly, while still providing for reasonable performance. Adjust the common lcd code to support sandbox. For command-line runs we do not want the LCD to be displayed, so add a --show_lcd option to enable it.

* sandbox: Add SDL library for LCD, keyboard, audioSimon Glass2014-03-17-0/+467
| | | | | | | | | | | | | | | | | 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.

* sandbox: Add -j option to indicate a jump from a previous U-BootSimon Glass2014-03-17-1/+18
| | | | | | | | | | In order to support the 'go' command we allow the jumping U-Boot to pass its filename to the new U-Boot image. This can then be used to delete that image if required.

* sandbox: Add os_jump_to_image() to run another executableSimon Glass2014-03-17-0/+108
| | | | | | | | For some tests it is useful to be able to run U-Boot again but pass on the same memory contents. Add a function to achieve this. Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>

* cros_ec: Correct comparison between signed and unsigned numbersSimon Glass2014-03-17-16/+18
| | | | | | | | | | | | | | | | | | | | | Due to signed/unsigned comparison, '< sizeof(struct)' does not do the right thing, since if ec_command() returns a -ve number we will consider this be success. Adjust all comparisons to avoid this problem. This error was found with sandbox, which gives a segfault in this case. On ARM we may instead silently fail. We should also consider turning on -Wsign-compare to catch this sort of thing in future.

| | | | | | | | | | | | | | | Version 1 protocols (without command version) were already no longer supported in cros_ec.c. This removes some dead code from the cros_ec_i2c driver. Version 2 protcols (with command version) are now called protocol_version=2, instead of cmd_version_is_supported=1. A subsequent change will introduce protocol version 3 for SPI.

* cros_ec: Support systems with no EC interruptSimon Glass2014-03-17-4/+30
| | | | | | | | | | Some systems do not have an EC interrupt. Rather than assuming that the interrupt is always present, and hanging forever waiting for more input, handle the missing interrupt. This works by reading key scans only until we get an identical one. This means the EC keyscan FIFO is empty.
