2017-05-17SPL: FIT: allow loading multiple imagesAndre Przywara
So far we were not using the FIT image format to its full potential: The SPL FIT loader was just loading the first image from the /images node plus one of the listed DTBs. Now with the refactored loader code it's easy to load an arbitrary number of images in addition to the two mentioned above. As described in the FIT image source file format description, iterate over all images listed at the "loadables" property in the configuration node and load every image at its desired location. This allows to load any kind of images: - firmware images to execute before U-Boot proper (for instance ARM Trusted Firmware (ATF)) - firmware images for management processors (SCP, arisc, ...) - firmware images for devices like WiFi controllers - bit files for FPGAs - additional configuration data - kernels and/or ramdisks The actual usage of this feature would be platform and/or board specific. Also update the FIT documentation to mention the new SPL feature and provide an example .its file to demonstrate its features.

2017-05-15omap5: Migrate CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC to KconfigTom Rini
While in theory this value could be used in places outside of "omap5" (such as OMAP4), we only make use of it today in OMAP5, so place the Kconfig entry there. Given that Kconfig lets us provide a default, we drop CONFIG_DEFAULT_OMAP_RESET_TIME_MAX_USEC entirely. The contents of doc/README.omap-reset-time make a good help entry, so adjust them slightly and delete the file. Move the comment about range to where we use the value now, and have Kconfig enforce the upper bound. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-05-10Allow boards to initialize the DT at runtime.Alex Deymo
In some boards like the Raspberry Pi the initial bootloader will pass a DT to the kernel. When using U-Boot as such kernel, the board code in U-Boot should be able to provide U-Boot with this, already assembled device tree blob. This patch introduces a new config option CONFIG_OF_BOARD to use instead of CONFIG_OF_EMBED or CONFIG_OF_SEPARATE which will initialize the DT from a board-specific funtion instead of bundling one with U-Boot or as a separated file. This allows boards like the Raspberry Pi to reuse the device tree passed from the bootcode.bin and start.elf firmware files, including the run-time selected device tree overlays.

2017-04-05rockchip: rk3399: spl: make SPL boot-order configurable via /chosenPhilipp Tomsich
The RK3399 does not have any boot selection pins and the BootROM probes the boot interfaces using the following boot-order: 1. SPI 2. eMMC (sdhci in DTS) 3. SD card (sdmmc in DTS) 4. USB loader For ease of deployment, the SPL stage should mirror the boot order of the ROM and use the same probing order (assuming that valid images can be detected by SPL) unless instructed otherwise. The boot-order can then be configured via the 'u-boot,spl-boot-order' property in the chosen-node of the DTS. While this approach is easily extensible to other boards, it is only implemented for the RK3399 for now, as the large SRAM on the RK3399 makes this easy to fit the needed infrastructure into SPL and our production setup already runs with DM, OF_CONTROL and BLK in SPL. The new boot-order property is expected to be used in conjunction with FIT images (and all legacy image formats disabled via Kconfig). A boot-sequence with probing and fallthroughs from SPI via eMMC to SD card (i.e. &spiflash, &sdhci, &sdmmc) has been validated on the RK3399-Q7.

2017-03-26drivers/net/phy: add fixed-phy / fixed-link supportHannes Schmelzer
This patch adds support for having a "fixed-link" to some other MAC (like some embedded switch-device). For this purpose we introduce a new phy-driver, called "Fixed PHY". Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is described with a subnode below ethernet interface. Most ethernet drivers (unfortunately not all are following same scheme for searching/attaching phys) are calling "phy_connect(...)" for getting a phy-device. At this point we link in, we search here for a subnode called "fixed- link", once found we start phy_device_create(...) with the special phy- id PHY_FIXED_ID (0xa5a55a5a). During init the "Fixed PHY" driver has registered with this id and now gets probed, during probe we get all the details about fixed-link out of dts, later on the phy reports this values.

2017-03-23dm: Add callback to modify the device treemario.six@gdsys.cc
Certain boards come in different variations by way of utilizing daughter boards, for example. These boards might contain additional chips, which are added to the main board's busses, e.g. I2C. The device tree support for such boards would either, quite naturally, employ the overlay mechanism to add such chips to the tree, or would use one large default device tree, and delete the devices that are actually not present. Regardless of approach, even on the U-Boot level, a modification of the device tree is a prerequisite to have such modular families of boards supported properly. Therefore, we add an option to make the U-Boot device tree (the actual copy later used by the driver model) writeable, and add a callback method that allows boards to modify the device tree at an early stage, at which, hopefully, also the application of device tree overlays will be possible.

2017-03-16dm: allow limiting pre-reloc markings to spl or tplHeiko Stübner
Right now the u-boot,dm-pre-reloc flag will make each marked node always appear in both spl and tpl. But systems needing an additional tpl might have special constraints for each, like the spl needing to be very tiny. So introduce two additional flags to mark nodes for only spl or tpl environments and introduce a function dm_fdt_pre_reloc to automate the necessary checks in code instances checking for pre-relocation flags. The behaviour of the original flag stays untouched and still marks a node for both spl and tpl.
