* x86: Add an ICH6 pin configuration driverSimon Glass2016-03-17-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a driver which sets up the pin configuration on x86 devices with an ICH6 (or later) Platform Controller Hub. The driver is not in the pinctrl uclass due to some oddities of the way x86 devices work: - The GPIO controller is not present in I/O space until it is set up - This is done by writing a register in the PCH - The PCH has a driver which itself uses PCI, another driver - The pinctrl uclass requires that a pinctrl device be available before any other device can be probed It would be possible to work around the limitations by: - Hard-coding the GPIO address rather than reading it from the PCH - Using special x86 PCI access to set the GPIO address in the PCH However it is not clear that this is better, since the pin configuration driver does not actually provide normal pin configuration services - it simply sets up all the pins statically when probed. While this remains the case, it seems better to use a syscon uclass instead. This can be probed whenever it is needed, without any limitations. Also add an 'invert' property to support inverting the input. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

* | mkimage: Support placing data outside the FITSimon Glass2016-03-14-1/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One limitation of FIT is that all the data is 'inline' within it, using a 'data' property in each image node. This means that to find out what is in the FIT it is necessary to scan the entire file. Once loaded it can be scanned and then the images can be copied to the correct place in memory. In SPL it can take a significant amount of time to copy images around in memory. Also loading data that does not end up being used is wasteful. It would be useful if the FIT were small, acting as a directory, with the actual data stored elsewhere. This allows SPL to load the entire FIT, without the images, then load the images it wants later. Add a -E option to mkimage to request that it output an 'external' FIT.

* | mkimage: Support adding device tree files to a FITSimon Glass2016-03-14-0/+13
| | | | | | | | | | | | | | | | | | | | | | To make the auto-FIT feature useful we need to be able to provide a list of device tree files on the command line for mkimage to add into the FIT. Add support for this feature. So far there is no support for hashing or verified boot using this method. For those cases, a .its file must still be provided. Signed-off-by: Simon Glass <sjg@chromium.org>
* | mkimage: Support automatic creating of a FIT without a .itsSimon Glass2016-03-14-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present, when generating a FIT, mkimage requires a .its file containing the structure of the FIT and referring to the images to be included. Creating the .its file is a separate step that makes it harder to use FIT. This is not required for creating legacy images. Often the FIT is pretty standard, consisting of an OS image, some device tree files and a single configuration. We can handle this case automatically and avoid needing a .its file at all. To start with, support automatically generate the FIT using a new '-f auto' option. Initially this only supports adding a single image (e.g. a linux kernel) and a single configuration.

| | | | | | | | | | | | | | Since commit ad1ecd2063da ("fdt: Build a U-Boot binary without device tree") and commit 03c25bcd263a ("fdt: Build an SPL binary without device tree"), we can use shorter file names for the output images. The default configuration for UniPhier SoCs enables CONFIG_OF_SEPARATE and CONFIG_SPL_OF_CONTROL. In this case, spl/u-boot-spl.bin is the same as spl/u-boot-spl-dtb.bin. Likewise, u-boot.img is the same as as u-boot-dtb.img. So, this change of the flow has no impact.

| * distro bootcmd: make net boot only optionally start USBStephen Warren2016-01-28-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the distro boot commands always enumerate USB devices before performing network operations. However, depending on the board and end- user configuration, network devices may not be attached to USB, and so enumerating USB may not be necessary. Enhance the scripts to make this step optional, so that the user can decrease boot time if they don't need USB. This change is performed by moving the "usb start" invocation into a standalone variable. If the user desires, they can replace that variable's value with some no-op command such as "true" instead. Booting from a USB storage device always needs to enumerate USB devices, so this action is still hard-coded.
