2020-10-27spl: Use standard FIT entriesMichal Simek1-0/+84
SPL is creating fit-images DT node when loadables are recorded in selected configuration. Entries which are created are using entry-point and load-addr property names. But there shouldn't be a need to use non standard properties because entry/load are standard FIT properties. But using standard FIT properties enables option to use generic FIT functions to descrease SPL size. Here is result for ZynqMP virt configuration: xilinx_zynqmp_virt: spl/u-boot-spl:all -82 spl/u-boot-spl:rodata -22 spl/u-boot-spl:text -60 The patch causes change in run time fit image record. Before: fit-images { uboot { os = "u-boot"; type = "firmware"; size = <0xfd520>; entry-point = <0x8000000>; load-addr = <0x8000000>; }; }; After: fit-images { uboot { os = "u-boot"; type = "firmware"; size = <0xfd520>; entry = <0x8000000>; load = <0x8000000>; }; }; Replacing calling fdt_getprop_u32() by fit_image_get_entry/load() also enables support for reading entry/load properties recorded in 64bit format.

2018-01-16doc: FIT image: fix incorrect description of DT node unit addressAndre Przywara1-26/+26
The DT spec demands a unit-address in a node name to match the "reg" property in that node. Newer dtc versions will throw warnings if this is not the case. Fix all occurences in the FIT image documentation files where this was not observed, to not give bad examples to the reader. Signed-off-by: Andre Przywara <andre.przywara@arm.com>
2017-05-17SPL: FIT: allow loading multiple imagesAndre Przywara1-0/+21
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.

2014-06-05FDT: Fix DTC repository referencesJon Loeliger1-1/+4
The Device Tree Compiler (DTC) used to have its master repository located on jdl.com. While it is still there, its official, new, shiny location is on kernel.org here: git://git.kernel.org/pub/scm/utils/dtc/dtc.git Update a few references to point there instead.
