Move the AES-128-CBC encryption function implemented in tegra20-common/crypto.c into lib/aes.c . This is well re-usable common code. Moreover, clean the code up a bit and fix the kerneldoc-style annotations. Signed-off-by: -

Heiko Schocher authored
based on patch from andreas@oetken.name: http://patchwork.ozlabs.org/patch/294318/ commit message: I currently need support for rsa-sha256 signatures in u-boot and found out that the code for signatures is not very generic. Thus adding of different hash-algorithms for rsa-signatures is not easy to do without copy-pasting the rsa-code. I attached a patch for how I think it could be better and included support for rsa-sha256. This is a fast first shot. aditionally work: - removed checkpatch warnings - removed compiler warnings - rebased against current head Signed-off-by:

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.

It is useful for Cltl-C to be handled by U-Boot as it is on other boards. But it is also useful to be able to terminate U-Boot with Ctrl-C. Add an option to enable signals while in raw mode, and make this the default. Add an option to leave the terminal cooked, which is useful for redirecting output. Signed-off-by: -

Unfortunately SDL requires getenv() to operate, since it wants to figure out the display type. U-Boot has its own getenv() and they conflict. As a work-around use #define to resolve the conflict. A better but more complex solution might be to rename some U-Boot symbols at link time. SDL audio is not functional at present, likely due to a related issue. Note: Vic Yank wrote a script for this, filed in crbug.com/271125. Reviewed-by:

The i2s code is in fact Samsung-specific, but there might be other implementation. Move this code into its own file. This makes it slightly more obviously how to adjust the code to support another SoC, when someone takes this task on. Also drop non-FDT support, since it isn't used on Exynos 5. Tested-by:

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. Tested-by:

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. Tested-by:

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. Reviewed-by:

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. Reviewed-by:

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. Tested-by:

At present we use U-Boot's filesystem layer to read the sandbox device tree, but this is problematic since it relies on a temporary feauture added there. Since we plan to implement proper block layer support for sandbox, change this code to use the os layer functions instead. Also use the new fdt_create_empty_tree() instead of our own code.
