2021-08-01sunxi: Select environment MMC based on boot deviceSamuel Holland1-0/+14
Currently, the environment is always stored in eMMC if eMMC is enabled in the config. This means images written to SD and eMMC will cross- contaminate their environments unless the configuration is changed. By dropping the device number from the environment location string and implementing mmc_get_env_dev, we will always use the environment from the boot device when booting from SD/eMMC.

2021-07-10sunxi: board: Add H616 MMC2 pinsAndre Przywara1-0/+13
We hardcode the pinctrl setting for the MMC controllers in boards.c, since we need them also in the SPL, where there is no DT yet. Add the respective setting for the H616 SoC, to enable eMMC on boards with this SoC as well. Also to make diagnosing this problem easier, print a warning if a board tries to setup MMC2 pins without a respective SoC setting being defined.

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.

2021-01-26sunxi: Properly check for SATAPWR and MACPWRAndre Przywara1-12/+22
The #ifdef CONFIG_xxxPWR conditionals were not working as expected, as string Kconfig symbols are always "defined" from the preprocessor's perspective. This lead to unnecessary calls to the GPIO routines, but also always added a half a second delay to wait for a SATA disk to power up. Many thanks to Peter for pointing this out! Fix this by properly comparing the Kconfig symbols against the empty string. strcmp() would be nicer for this, but GCC does not optimise this away, probably due to our standalone compiler switches.

2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada1-2/+2
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.

2018-12-29Revert "sunxi: board: Print error after power initialization fails"From: Karl Palsson1-10/+8
Commit a8011eb84dfa("sunxi: board: Print error after power initialization fails") moved the DRAM init after the increase of the CPU clock frequency. This lead to various DRAM initialisation failures on some boards (hangs or wrong size reported, on a NanoPi Duo2 and OrangePi Zero, for instance). Lowering the CPU frequency significantly (for instance to 408 MHz) seems to work around the problem, so this points to some timing issues in the DRAM code. Debugging this sounds like a larger job, so let's just revert this patch to bring back those boards. Beside this probably unintended change the patch just moved the error message around, so reverting this is not a real loss. This reverts commit a8011eb84dfac5187cebf00ed8bc981bdb5c1fa1.

2018-10-29sunxi: store DRAM size in SPL headerAndre Przywara1-1/+27
At the moment we rely on the infamous get_ram_size() function to learn the actual DRAM size in U-Boot proper. This function has two issues: 1) It only works if the DRAM size is a power of two. We start to see boards which have 3GB of (usable) DRAM, so this does not fit anymore. 2) As U-Boot has no notion of reserved memory so far, it will happily ride through the DRAM, possibly stepping on secure-only memory. This could be a region of DRAM reserved for OP-TEE or some other secure payload, for instance. It will most likely crash in that case. As the SPL DRAM init routine has very accurate knowledge of the actual DRAM size, lets propagate this wisdom to U-Boot proper. We re-purpose a currently reserved word in our SPL header for that. The SPL itself stores the detected DRAM size there, and bumps the SPL header version number in that case. U-Boot proper checks for a valid SPL header and a high enough version number, then uses the DRAM size from there. If the SPL header field is not sufficient, we fall back to the old DRAM scanning routine. Part of the DRAM might be present and probed by SPL, but not accessible by the CPU. They're restricted in the main U-Boot binary, when accessing the DRAM size from SPL header.

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.

Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2018-01-27sunxi: Transition from the MMC to a FAT-based environmentMaxime Ripard1-0/+16
The current environment has been hardcoded to an offset that starts to be an issue given the current size of our main U-Boot binary. By implementing a custom environment location routine, we can always favor the FAT-based environment, and fallback to the MMC if we don't find something in the FAT partition. We also implement the same order when saving the environment, so that hopefully we can slowly migrate the users over to FAT-based environment and away from the raw MMC one. Eventually, and hopefully before we reach that limit again, we will have most of our users using that setup, and we'll be able to retire the raw environment, and gain more room for the U-Boot binary.

If the USB Ethernet gadget is not yet enabled, the call of usb_ether_init in board/sunxi/board.c will lead to undefined reference error when building. Fix this problem.
