2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2018-07-25fdt_support: make fdt_fixup_mtdparts() prototype more specificMasahiro Yamada
The second argument of fdt_fixup_mtdparts() is an opaque pointer, 'void *node_info', hence callers can pass any pointer. Obviously, fdt_fixup_mtdparts() expects 'struct node_info *' otherwise, it crashes run-time. Change the prototype so that it is compile-time checked. Also, add 'const' qualifier to it so that callers can constify the struct node_info arrays. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-11-26spl: fit: add SPL_FIT_IMAGE_TINY config to reduce code-sizePhilipp Tomsich
A minor code-size increase from the changes for tracking the os-type of FIT images and from infrastructure for recording the loadables into the the loaded FDT, broke the builds for sun50i and some OMAP2+ devices. This change adds a new config option (enabled by default for MACH_SUN50I, MACH_SUN50I_H5 and ARCH_OMAP2PLUS) that does skips these processing steps (bringing code size down to below the limit again). The os-type is not evaluated, but assumed to be IH_OS_UBOOT (i.e. taking the code-paths intended for backward-compatibility). Note that enabling this config option precludes any useful downstream processing, such as utilising a special calling convention for ATF or OPTEE, based on the os-type of the loadables.

2017-11-26spl: fit: implement fdt_record_loadablePhilipp Tomsich
During the loading of more complex FIT images (e.g. when the invoked next stage needs to find additional firmware for a power-management core... or if there are multiple images for different privilege levels started in parallel), it is helpful to create a record of what images are loaded where: if a FDT is loaded for one of the next stages, it can be used to convey the status and location of loadables. This adds a fdt_record_loadable() function that can be invoked to record the status of each loadable below the /fit-images path.

Sometimes devicetree nodes and or properties are added out of the u-boot console, maybe through some script or manual interaction.

Avoid clearing the reg property in the memory DT node if no memory banks have been specified for a board (CONFIG_NR_DRAM_BANKS == 0). This allows boards to let U-Boot skip the DT memory tinkering in case other firmware has already setup the node properly before.

2015-06-05fdt: Pass the device serial number through devicetreePaul Kocialkowski
Before device-tree, the device serial number used to be passed to the kernel using ATAGs (on ARM). This is now deprecated and all the handover to the kernel should now be done using device-tree. Thus, this passes the serial-number property to the kernel using the serial-number property of the root node, as expected by the kernel. The serial number is a string that somewhat represents the device's serial number. It might come from some form of storage (e.g. an eeprom) and be programmed at factory-time by the manufacturer or come from identification bits available in e.g. the SoC.

Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this.
