Use CONFIG_IS_ENABLED() macro, which provides more convenient way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs for both SPL and U-Boot proper. CONFIG_IS_ENABLED(DM_I2C) expands to: - 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y', - 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y', - 0 otherwise.

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>

We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them.

2019-03-11arm: exynos: Detect revision later, when all resources are readyKrzysztof Kozlowski2-4/+35
Detection of board revision is done early - before power setup. In case of Odroid XU3/XU4/HC1 family, the detection is done using ADC which is supplied by LDO4/VDD_ADC regulator. This regulator could be turned off (e.g. by kernel before reboot). If ADC is used early, the regulators are not yet available and the detection won't work. Split the revision detection out of set_board_type() into separate function called later - either when displaying board info (in late mode) or during misc_init_r. The idea is that set_board_type() will be called early so its method of detection are limited to flattened device tree (exynos5-dt-types.c for Exynos5) or GPIO (odroid.c for Exynos4412). The newly added set_board_revision() can be called only later, when resources like regulator are available. This is necessary to fix the detection of Odroid HC1 after reboot, if kernel turned off the LDO4 regulator.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini7-15/+7
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>

USB3.0 ports are used for build-in JMicron USB to SATA bridge and Gigabit R8152 ethernet chips. HC1 uses only passive cooling. This patch also updates Odroid's ADCmax array and reduces ADC tolerance to 1% to ensure that XU4 and HC1 revisions are properly detected. I've tested this with XU3, XU3-lite, XU4 and HC1 boards.

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada2-2/+2
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux.
