2025-03-13Raspberry Pi: Keep warnings from firmware in DT, if anyFiona Klute
The /chosen/user-warnings property is created by the RPi firmware if there are warnings to report, keep it to make debugging easier. For example, if the firmware config.txt contains "dtoverlay=error-example" and that example references an undefined symbol "&nosuchdev" the warning can be read after boot: $ cat /proc/device-tree/chosen/user-warnings dterror: can't find symbol 'nosuchdev' Failed to resolve overlay 'error-example' Signed-off-by: Fiona Klute <[email protected]> Reviewed-by: Matthias Brugger <[email protected]> Signed-off-by: Peter Robinson <[email protected]>

2024-12-18fdt: Swap the signature for board_fdt_blob_setup()Simon Glass
This returns a devicetree and updates a parameter with an error code. Swap it, since this fits better with the way U-Boot normally works. It also (more easily) allows leaving the existing pointer unchanged. No yaks were harmed in this change, but there is a very small code-size reduction. For sifive, the OF_BOARD option must be set for the function to be called, so there is no point in checking it again. Also OF_SEPARATE is defined always.

This was added in commit 45a6d231b2f (bcm2835_wdt: support for the BCM2835/2836 watchdog), which did do 'select HW_WATCHDOG'. That incarnation of the watchdog driver later got removed in c7adc0b5f98 (watchdog: bcm2835_wdt: Remove unused BCM283x watchdog driver and its references), but this block was left behind. Another rpi watchdog driver has since been added, but that does not select HW_WATCHDOG, so this remains dead and unused. Remove it.

When raspberrpi-4b platform boots up, there are 2 sets of same bootup log displayed on HDMI monitor screen, it looks like the screen is split into 2 parts. The root cause is that video format of u-boot is different from kernel. The fixing "a8r8g8b8" video format is used in u-boot, but "r5g6b5" video format from framebuffer node is used in kernel image.

Specificaly copy: * /model: The firmware provides a more specific string * /memreserve: The firmware defines a reserved range, better keep it * emmc2bus and pcie0 dma-ranges: The C0T revision of the bcm2711 Soc (as present on rpi 400 and some rpi 4B boards) has different values for these then the B0T revision. So these need to be adjusted to boot on these boards * blconfig: The firmware defines the memory area where the blconfig stored.

2021-09-07arm: Disable ATAGs supportTom Rini
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 Szyprowski
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 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 <[email protected]>
2020-05-17efi_loader: round the memory area in efi_add_memory_map()Michael Walle
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 <[email protected]> Add missing comma in sunxi_display.c.
