2024-08-06am33xx: Use regular spl_board_init instead of am33xx_spl_board_initPaul Kocialkowski
The am33xx_spl_board_init function was introduced as a way to add board-specific SPL init for AM33xx devices since the spl_board_init function was already used for SoC-specific init. Now that the SoC-specific SPL init was moved to spl_soc_init, we can use spl_board_init for this purpose and get rid of am33xx_spl_board_init. Rename the function in board files and enable the related config option for concerned boards. Signed-off-by: Paul Kocialkowski <paulk@sys-base.io> Reviewed-by: Tom Rini <trini@konsulko.com>

There is a number of users that use uclass_first_device to access the first and (assumed) only device in uclass. Some check the return value of uclass_first_device and also that a device was returned which is exactly what uclass_first_device_err does.

2021-01-05dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()Simon Glass
The current macro is a misnomer since it does not declare a device directly. Instead, it declares driver_info record which U-Boot uses at runtime to create a device. The distinction seems somewhat minor most of the time, but is becomes quite confusing when we actually want to declare a device, with of-platdata. We are left trying to distinguish between a device which isn't actually device, and a device that is (perhaps an 'instance'?) It seems better to rename this macro to describe what it actually is. The macros is not widely used, since boards should use devicetree to declare devices. Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is declaring a new driver_info record, not a device. Signed-off-by: Simon Glass <sjg@chromium.org>

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>

2019-12-15dm: gpio: Allow control of GPIO uclass in SPLSimon Glass
At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass is included in SPL/TPL without any control for boards. Some boards may want to disable this to reduce code size where GPIOs are not needed in SPL or TPL. Add a new Kconfig option to permit this. Default it to 'y' so that existing boards work correctly. Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to preserve the current behaviour. Also update the 74x164 GPIO driver since it cannot build with SPL. This allows us to remove the hacks in config_uncmd_spl.h and Makefile.uncmd_spl (eventually those files should be removed).

The board_early_init_f() inits clock before initing pinmux. However, the clock configuration code might need to adjust PMIC settings of a PMIC on I2C bus (e.g. board/ti/am335x/board.c does that). If the I2C bus pin muxing is not configured before attempting to communicate with the PMIC, the communication will silently fail and the prcm_init() may configure fast enough CPU clock that the default voltage provided by the PMIC would be insufficient and the platform would become unstable.

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>

Parse these registers during SPL boot and jump to the kernel resume vector if the device is waking up from RTC-only modewith DDR in Self-refresh. The RTC scratch register layout used is: SCRATCH0 : bits00-31 : kernel resume address SCRATCH1 : bits00-15 : RTC magic value used to detect valid config SCRATCH1 : bits16-31 : board type information populated by bootloader During the normal boot path the SCRATCH1 : bits16-31 are updated with the eeprom read board type data. In the rtc_only boot path the rtc scratchpad register is read and the board type is determined and correspondingly ddr dpll parameters are set. This is done so as to avoid costly i2c read to eeprom.

2017-06-05ti816x: Rework DDR initialization sequenceTom Rini
The ti816x/am389x SoC is the first generation in what U-Boot calls the "am33xx" family. In the first generation of this family the DDR initialization sequence is quite different from all of the subsequent generations. Whereas with ti814x (second generation) we can easily work the minor differenced between that and am33xx (third generation), our attempts to do this for ti816x weren't sufficient. Rather than add a large amount of #ifdef logic to make this different sequence work we add a new file, ti816x_emif4.c to handle the various required undocumented register writes and sequence and leverage what we can from arch/arm/mach-omap2/am33xx/ddr.c still. As DDR2 has similar problems today but I am unable to test it, we drop the DDR2 defines from the code rather than imply that it works by leaving it. We also remove a bunch of other untested code about changing the speed the DDR runs at. Signed-off-by: Tom Rini <trini@konsulko.com>
