| * x86: minnowmax: Adjust U-Boot environment address in SPI flashBin Meng2016-05-23-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently U-Boot environment address is at offset 0x7fe00 of a 8MB SPI flash. When creating a partial u-boot.rom image without flash descriptor and ME firmware, U-Boot actually occupies the last 1MB of the flash, and reprograming U-Boot causes previous environment settings get lost which is not convenient during testing. Adjust the environment address to 0x6ef000 instead (before the MRC cache data region in the flash).

* ARM: uniphier: switch to raw U-Boot imageMasahiro Yamada2016-03-24-6/+16
| | | | | | | | | | | | | | | | | 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...)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
