2024-03-30arm: xea: Add support for reading SoM (CPU) board HW revisionLukasz Majewski2-0/+60
The XEA board now has several HW revisions for SoM boards. This patch provides support for reading this revision ID values in early u-boot proper as production devices boot via falcon boot with correct DTB flashed at production (so there is no need to alter SPL). Additionally, the maximal SPL size (~55KiB) constraint is not allowing having even simplified FIT support in it. As a result it was necessary to handle reading GPIOs values solely in u-boot proper as one configuration (i.e. 'single binary' - imx28_xea_sb_defconfig) is not using SPL framework. Moreover, the 'board_som_rev' environment variable will be used to point correct configuration from the Linux FIT file. Additionally, as now XEA has its second HW revision - this information is printed when u-boot proper starts. Signed-off-by: Lukasz Majewski <lukma@denx.de>
2024-03-30arm: spl: Add definition for PHY reset GPIO for XEA HW rev. 2Lukasz Majewski1-1/+2
The imx287 based XEA board's revision 2 uses GPIO_3_21 for PHY reset It is safe to keep the GPIO_2_13 as well, as in the SPL SPI1 is not used for transmission. This simplifies the code, as the proper configuration is performed either in falcon boot's read DTB or in u-boot proper (with correct FIT configuration chosen).

2023-08-09treewide: rework linker symbol declarations in sections headerShiji Yang1-0/+1
1. Convert all linker symbols to char[] type so that we can get the corresponding address by calling array name 'var' or its address '&var'. In this way, we can avoid some potential issues[1]. 2. Remove unused symbol '_TEXT_BASE'. It has been abandoned and has not been referenced by any source code. 3. Move '__data_end' to the arch x86's own sections header as it's only used by x86 arch. 4. Remove some duplicate declared linker symbols. Now we use the standard header file to declare them. [1] This patch fixes the boot failure on MIPS target.

The new configs/imx28_xea_sb_defconfig is introduced to facilitate building the single binary u-boot.sb fox XEA board. The biggest distinction from "normal" XEA imx28_xea_sb_defconfig is support for USB mass storage devices (pen drives). To achieve that, the CONFIG_DM_USB is enabled and supported.

2022-02-05arm: xea: Modify board code to generate single binary u-bootLukasz Majewski2-1/+8
This change provides the possibility to build XEA (imx287 based) board U-Boot as a single binary (without support for CONFIG_SPL_FRAMEWORK). The generated u-boot.sb can be used in the factory environment to for example perform initial setup or HW testing. It can be used with 'uuu' utility (SDPS: boot -f /srv/tftp/xea/u-boot.sb) In the configs/imx28_xea_defconfig one needs to disable following configs: # CONFIG_SPL_BLK is not set # CONFIG_SPL_FRAMEWORK is not set The board_init_ll() is used in arch/arm/cpu/arm926ejs/mxs/start.S, which is utilized when CONFIG_SPL_FRAMEWORK is disabled. However, when it is enabled - the arch/arm/cpu/arm926ejs/start.S is used, which requires the lowlevel_init() function. Signed-off-by: Lukasz Majewski <lukma@denx.de>
2021-12-27Finish converting CONFIG_WATCHDOG, HW_WATCHDOG and WDT to KconfigTom Rini1-0/+2
Because of how these symbols work, and the remaining board config.h file uses, we need to do these at the same time. In some cases we just get to move rather directly to the defconfigs. A few cases require manual intervention. For the case of the eb_cpu5282 we need to select HW_WATCHDOG for the target, given how it's implemented. For the cases of m53menlo, dh_imx6, display5, and display5_factory we disable SPL watchdog support as the particular combination of options they want would require either more symbols or enabling SPL_DM.

2021-03-02reset: Remove addr parameter from reset_cpu()Harald Seiler1-1/+1
Historically, the reset_cpu() function had an `addr` parameter which was meant to pass in an address of the reset vector location, where the CPU should reset to. This feature is no longer used anywhere in U-Boot as all reset_cpu() implementations now ignore the passed value. Generic code has been added which always calls reset_cpu() with `0` which means this feature can no longer be used easily anyway. Over time, many implementations seem to have "misunderstood" the existence of this parameter as a way to customize/parameterize the reset (e.g. COLD vs WARM resets). As this is not properly supported, the code will almost always not do what it is intended to (because all call-sites just call reset_cpu() with 0). To avoid confusion and to clean up the codebase from unused left-overs of the past, remove the `addr` parameter entirely. Code which intends to support different kinds of resets should be rewritten as a sysreset driver instead. This transformation was done with the following coccinelle patch: @@ expression argvalue; @@ - reset_cpu(argvalue) + reset_cpu() @@ identifier argname; type argtype; @@ - reset_cpu(argtype argname) + reset_cpu(void) { ... } Signed-off-by: Harald Seiler <hws@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>

2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada4-4/+4
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>
2020-07-16arm: Add extra boot device (UART) to run Ymodem u-boot.img boot on XEA (imx28)Lukasz Majewski1-0/+1
This commit enables imx28 based XEA board's u-boot.sb (SPL) to download u-boot proper (u-boot.img) via Ymodem protocol. This is extremely useful in the recovery scenario where u-boot.sb is downloaded via uuu utility to SDRAM [*], and then one can upload u-boot proper via serial console to fully debrick the device. Note - debricking procedure of imx28 devices: - NXP's original USB based tools (like mxsldr or uuu) expect single u-boot.sb which is a relic of the old U-Boot (~2013) without SPL and U-Boot proper distinction.
