2025-07-10arm: imx: Remove the rest of i.MX31 supportTom Rini
With the removal of the last i.MX31 platform we can remove the rest of the underlying architecture code as well. Fixes: f247354708ec ("arm: Remove mx31pdk board") Signed-off-by: Tom Rini <[email protected]> Acked-by: Peng Fan <[email protected]>

2022-12-05global: Move remaining CONFIG_SYS_* to CFG_SYS_*Tom Rini
The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini <[email protected]> Reviewed-by: Simon Glass <[email protected]>
2022-05-20ARM: imx: imx31: Introduce and use UART_BASE_ADDR(n)Marek Vasut
Introduce helper macro UART_BASE_ADDR(n), which returns Nth UART base address. Convert all board configurations to this new macro. This is the first step toward switching CONFIG_MXC_UART_BASE to Kconfig. This is a clean up, no functional change. The new macro contains compile-time test to verify N is in suitable range. The test works such that it multiplies constant N by constant double-negation of size of a non-empty structure, i.e. it multiplies constant N by constant 1 in each successful compilation case. The non-empty structure may contain C11 _Static_assert(), make use of this and place the kernel variant of static assert in there, so that it performs the compile-time check for N in the correct range. Note that it is not possible to directly use static_assert in compound statements, hence this convoluted construct.

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 <[email protected]>
2020-05-18arm: Don't include common.h in header filesSimon Glass
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 <[email protected]>

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 <[email protected]>

2015-09-02imx-common: consolidate macros and prototypes into sys_proto.hPeng Fan
Move most macro definitions and prototypes into "arch/arm/include/asm/imx-common/sys_proto.h" to avoid duplicated function prototypes and marco definitions for different i.MX SoCs. This patch do not remove the sys_proto.h for different i.MX SoCs, because we need to modify lots of driver code and others. This patch remove duplicated macros and prototypes and incude "sys_proto.h" of imx-common for each sys_proto.h of different i.MX platforms. Then later we should avoid add stuff in sys_proto.h of each platform, and modify driver to include common sys_proto.h.

This patch moves mx31 to the common timer functions added in commit 8dfafdd - Introduce common timer functions <Rob Herring> The (removed) mx31 timer code (specifically __udelay()) could deadlock at the 32-bit boundary of get_ticks(). get_ticks() returned a 32-bit value cast up to a 64-bit value. If get_ticks() + tmo in __udelay() crossed the 32-bit boundary, the while condition became unconditionally true and locks the processor. Rather than patch the specific mx31 issues, simply move everything over to the common code.
