* treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada2020-07-171-1/+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>
* arm: wandboard: move CONFIG_MXC_UART to defconfigHeinrich Schuchardt2020-06-221-0/+10
| | | | | | | | | | | | | For using a debug UART on the Wandboard CONFIG_MXC_UART=y must be set in the .config file. To avoid duplicate definitions move the setting from include/configs/wandboard.h to configs/wandboard_defconfig. Document the debug UART settings in the README.

* arm: Don't include common.h in header filesSimon Glass2020-05-182-0/+2
| | | | | | | | | | | It is bad practice to include common.h in other header files since it can bring in any number of superfluous definitions. It implies that some C files don't include it and thus may be missing CONFIG options that are set up by that file. The C files should include these themselves. Update some header files in arch/arm to drop this. Signed-off-by: Simon Glass <sjg@chromium.org>
* wandboard: Print the board version in board_late_init()Fabio Estevam2020-04-181-14/+9
| | | | | | | | | | | | | | | Since CONFIG_DISPLAY_BOARDINFO_LATE is no longer used, the checkboard() function is no longer called. As it is useful to print the board revision, print it inside board_late_init() instead. Also, to avoid GPIO errors related to using a GPIO without requesting it, move the gpio_request(REV_DETECTION, "REV_DETECT") call prior to its usage.

* wandboard: Fix version detection for mx6q/mx6dl revD1Fabio Estevam2020-04-181-2/+2
| | | | | | | | | | | | | | | | | | | | | The detection of the revD1 version is based on the presence of the PMIC. Currently revb1 device trees are used for mx6q/mx6dl variants, which do not have the PMIC nodes. This causes revD1 boards to be incorrectly be detected as revB1. Fix this issue by using the revd1 device trees, so that the PMIC node can be found and then the PMIC can be detected by reading its register ID. Imported the revd1 device trees from mainline kernel version 5.7-rc1.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-073-6/+3
| | | | | | | | | | | | | | | | | | | | 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>

The detection mechanism is to probe the PMIC and when it is found, then the revision of the board is revd1. As the detection is done via PMIC, we need to print the board version at a later stage via CONFIG_DISPLAY_BOARDINFO_LATE and also need to disable CONFIG_DISPLAY_BOARDINFO, which is done much earlier.

However, on wandboard design we need some additional configuration, such as enabling the 125 MHz AR8031 output that needs to be done in the board file.

* mx6: ddr: Allow changing REFSEL and REFR fieldsFabio Estevam2016-09-061-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently MX6 SPL DDR initialization hardcodes the REF_SEL and REFR fields of the MDREF register as 1 and 7, respectively for DDR3 and 0 and 3 for LPDDR2. Looking at the MDREF initialization done via DCD we see that boards do need to initialize these fields differently: $ git grep 0x021b0020 board/ board/bachmann/ot1200/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/ccv/xpress/imximage.cfg:DATA 4 0x021b0020 0x00000800 /* MMDC0_MDREF */ board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x7800 board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6qp.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6dlsabresd.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6slevk/imximage.cfg:DATA 4 0x021b0020 0x00001800 board/freescale/mx6sxsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/freescale/mx6sxsabresd/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/warp/imximage.cfg:DATA 4 0x021b0020 0x00001800 So introduce a mechanism for users to be able to configure REFSEL and REFR fields as needed. Keep all the mx6 SPL users in their current REF_SEL and REFR values, so no functional changes for the existing users.
