OF_HOSTFILE is used on sandbox configs only. Although it's pretty unique and not causing any confusions, we are better of having simpler config options for the DTB. So let's replace that with the existing OF_BOARD. U-Boot would then have only three config options for the DTB origin. - OF_SEPARATE, build separately from U-Boot - OF_BOARD, board specific way of providing the DTB - OF_EMBED embedded in the u-boot binary(should not be used in production Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Reviewed-by: Simon Glass <sjg@chromium.org>

2021-09-07arm: Disable ATAGs supportTom Rini1-2/+2
With the exceptions of ds109, ds414, icnova-a20-swac, nokia_rx51 and stemmy, disable ATAG support. A large number of platforms had enabled support but never supported a kernel so old as to require it. Further, some platforms are old enough to support both, but are well supported by devicetree booting, and have been for a number of years. This is because some of the ATAGs related functions have been re-used to provide the same kind of information, but for devicetree or just generally to inform the user. When needed still, rename these functions to get_board_revision() instead, to avoid conflicts. In other cases, these functions were simply unused, so drop them.

2021-02-18rpi: limit size of the RAM to the multiple of the MMU_SECTION_SIZEMarek Szyprowski1-0/+7
When RPi4 is booted from USB Mass Storage, the firmware reports 947MiB of the ARM memory (948 in case of the standard SD-card boot). This value is not MMU_SECTION_SIZE aligned, so the dram_bank_mmu_setup() skips mapping of the last 1MiB. This later causes u-boot in ARM 32bit mode to freeze, because it relocated itself into that unmapped memory and fails to execute. Fix this by limiting the size of the first bank to the multiple of MMU_SECTION_SIZE.

2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada1-1/+1
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>
2020-05-17efi_loader: round the memory area in efi_add_memory_map()Michael Walle1-2/+2
Virtually all callers of this function do the rounding on their own. Some do it right, some don't. Instead of doing this in each caller, do the rounding in efi_add_memory_map(). Change the size parameter to bytes instead of pages and remove aligning and size calculation in all callers. There is no more need to make the original efi_add_memory_map() (which takes pages as size) available outside the module. Thus rename it to efi_add_memory_map_pg() and make it static to prevent further misuse outside the module. Signed-off-by: Michael Walle <michael@walle.cc> Add missing comma in sunxi_display.c.

Up to now we only update the DRAM banks when we are define CONFIG_BCM2711. But our one binary approach uses a config that supports BCM2837 and BCM2711. As a result we only see one gibibyte of RAM on Raspberry Pi 4, even if it has more RAM. Fix this by calling dram_init_banksize.

To update the dram bank information from device-tree we use fdtdec_decode_ram_size() which expectes the the size-cells and address-cells to be defined in the memory node. For normal system RAM these values are defined in the root node. When the values differ from the default values defined in the spec, we can end up with wrong RAM bank information.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini3-7/+3
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>

2018-01-28bcm283x: Add pinctrl driverAlexander Graf1-2/+3
The bcm283x family of SoCs have a GPIO controller that also acts as pinctrl controller. This patch introduces a new pinctrl driver that can actually properly mux devices into their device tree defined pin states and is now the primary owner of the gpio device. The previous GPIO driver gets moved into a subdevice of the pinctrl driver, bound to the same OF node. That way whenever a device asks for pinctrl support, it gets it automatically from the pinctrl driver and GPIO support is still available in the normal command line phase.

2017-05-09Allow boards to initialize the DT at runtime.Alex Deymo1-0/+10
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.
