* dm: video: Add driver-model support to vesa graphicsSimon Glass2016-10-11-0/+57
| | | | | | | | | | Provide a function to run the Vesa BIOS for a given PCI device and obtain the resulting configuration (e.g. display size) for use by the video uclass. This makes it easier to write a video driver that uses vesa and supports driver model. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* dm: stdio: Allow lazy probing of video devicesSimon Glass2016-10-11-4/+83
| | | | | | | | | | | | At present all video devices are probed on start-up. It would be better to probe a device only when it is needed. This can happen if it is referenced in the stdout environment variable, for example. Add support for this by searching for a suitable device when needed, probing it, and finding the stdio device it creates.

* Revert "x86: broadwell: gpio: Remove the codes to set up pin control"Simon Glass2016-10-11-0/+7
| | | | | | | | | | | | | | | | | | | This makes the assumption that setting up pinctrl in cpu_init_r() is safe. On samus we need GPIOs before relocation in order to support power control. This commit fixes the following message on boot: initcall sequence ffe5c6f4 failed at call ffe01d3d (err=-1) ### ERROR ### Please RESET the board ### In any case it seems better to leave init to driver model, so that it can pick up the GPIO driver when it needs it. Since pinctrl is a dependency of the GPIO driver, we may as well put the dependency there and avoid these problems. This reverts commit 9769e05bcf79939bad23a719982dd1f85a110f3c.

| | | | | | | | | | | | | | Booting Linux kernel v4.7+ does not work since Linux kernel commit 974f221c "x86/boot: Move compressed kernel to the end of the decompression buffer". This patch adds the latest version of the setup_header struct, adding "init_size" which is needed since this commit referenced above.

| | | | | | | | | | | | | | | | | | | | | | | | To create the soc environment variable we concatenate two strings on the stack. So far, strcat has been used for the first string as well as for the second string. Since the variable on the stack is not initialized, the first strcat may not start using the first entry in the character array. This then could lead to an buffer overflow on the stack.
