2016-03-23ARM: uniphier: switch to raw U-Boot imageMasahiro Yamada
Now everything is done to load a raw U-Boot proper image instead of an mkimage-processed one (as far as I tested on NAND, eMMC, NOR). The SPL already knows the load address of the U-Boot proper without parsing its uImage header because the load address is defined by CONFIG_SYS_TEXT_BASE, assuming that the two images are generated from the same build. My main motivation of this switch is to use u-boot-with-spl.bin, a concatenation of u-boot-spl.bin and u-boot.bin. (I wish there were a concatenation of u-boot-spl.bin and u-boot.img...) Anyway, this commit would be useful for one-shot image burn. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2016-03-17x86: Add support for the samus chromebookSimon Glass
This adds basic support for chromebook_samus. This is the 2015 Pixel and is based on an Intel broadwell platform. Supported so far are: - Serial - SPI flash - SDRAM init (with MRC cache) - SATA - Video (on the internal LCD panel) - Keyboard Various less-visible drivers are provided to make the above work (e.g. PCH, power control and LPC). The platform requires various binary blobs which are documented in the README. The major missing feature is USB3 since the existing U-Boot support does not work correctly with Intel XHCI controllers.

2016-03-17x86: Add an ICH6 pin configuration driverSimon Glass
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>

2016-03-14mkimage: Support placing data outside the FITSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-03-14mkimage: Support adding device tree files to a FITSimon Glass
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>
2016-03-14mkimage: Support automatic creating of a FIT without a .itsSimon Glass
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.

2016-01-29distro bootcmd: make net boot only optionally start USBStephen Warren
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.
