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>

2020-04-22arm: mvebu: correct SPL boot configs for SPI/MMCJoel Johnson
Update mvebu SPL boot selection mechanism for the move to driver model usage by ensuring that the required driver support for SPI and MMC booting is available in SPL when the respective boot method is selected. Previously, all mvebu boards selected a boot method (implicitly MVEBU_SPL_BOOT_DEVICE_SPI for many) even if SPL booting wasn't used. This changes mvebu boot method selection to depend on SPL usage which resolves the issue with aarch64 boards which don't use SPL getting an implicit boot device selection resulting in unmet dependencies. The 32-bit arm boards do use SPL, but I'm led to conclude that most aren't intentionally using the MVEBU_SPL_BOOT_DEVICE selection since none have SPL_DM_SPI enabled in their defconfig even though they still implicitly select the SPI boot method. This also results in the new addition of SPL_GPIO_SUPPORT to helios4. The mainline dts for helios4 includes the cd-gpios entry for sdhci with identical addresses as the clearfog dts. I don't have a helios4 board to confirm, but based on the current source conclude that the board itself is either wired to pull the signal low for eMMC, or the default MMC boot isn't fully functional in mainline. In either case, as far as I can tell, including the GPIO support will at least cause no regression. Tested on SolidRun ClearFog devices.

2020-04-14arm64: mvebu: a37xx: improve code determining memory info structuresMarek Behún
Currently on Armada-37xx the mem_map structure is statically defined to map first 2 GB of memory as RAM region, and system registers and PCIe region device region. This is insufficient for when there is more RAM or when for example the PCIe windows is mapped to another address by the CPU Address Decoder. In the case when the board has 4 GB RAM, on some boards the ARM Trusted Firmware can move the PCIe window to another address, in order to maximize possible usable RAM. Also the dram_init and dram_init_banksize looks for information in device-tree, and therefore different device trees are needed for boards with different RAM sizes. Therefore we add code that looks at how the ARM Trusted Firmware has configured the CPU Address Decoder windows, and then we update the mem_map structure and compute gd->ram_size and gd->bd->bi_dram bank base addresses and sizes accordingly.

2019-05-03arm: mvebu: turris_omnia: add RESET button handlingMarek Behún
There is a Factory RESET button on the back side of the Turris Omnia router. When user presses this button before powering the device up and keeps it pressed, the microcontroller prevents the main CPU from booting and counts how long the RESET button is being pressed (and indicates this by lighting up front LEDs). The idea behind this is that the user can boot the device into several Factory RESET modes. This patch adds support for U-Boot to read into which Factory RESET mode the user booted the device. The value is an integer stored into the omnia_reset environment variable. It is 0 if the button was not pressed at all during power up, otherwise it is the number identifying the Factory RESET mode. This patch also changes bootcmd to a special hardcoded value if Factory RESET button was pressed during device powerup. This special bootcmd value sets the colors of all the LEDs on the front panel to green and then tries to load the rescue image from the SPI flash memory and boot it.

2019-04-23dm: core: Change platform specific translation-offset handlingStefan Roese
Testing has shown that the current DM implementation of a platform / board specific translation offset, as its needed for the SPL on MVEBU platforms is buggy. The translation offset is confingured too late, after the driver bind functions are run. This may result in incorrect address translations. With the current implementation its not possible to configure the offset earlier, as the DM code has not run at all. This patch now removed the set_/get_translation_offset() calls and moves the translation offset into the GD variable translation_offset. This variable will get used when CONFIG_TRANSLATION_OFFSET is enabled. This option is enabled only for MVEBU on ARM32 platforms, where its currenty needed and configured in the SPL.
