* reset: Remove addr parameter from reset_cpu()Harald Seiler2021-03-023-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly.

* treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada2020-07-174-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: caches: manage phys_addr_t overflow in mmu_set_region_dcache_behaviourPatrick Delaunay2020-05-011-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Solved the overflow on phys_addr_t type for start + size in mmu_set_region_dcache_behaviour() function. This overflow is avoided by dividing start and end by 2 before addition, and we only expecting that start and size are even. This patch doesn't change the current function behavior if the parameters (start or size) are not aligned on MMU_SECTION_SIZE. For example, this overflow occurs on ARM32 with: start = 0xC0000000 and size = 0x40000000 then start + size = 0x100000000 and end = 0x0. For information the function behavior change with risk of regression, if we just shift start and size before the addition. Example with 2MB section size: MMU_SECTION_SIZE 0x200000 and MMU_SECTION_SHIFT = 21 with start = 0x1000000, size = 0x1000000, - with the proposed patch, start = 0 and end = 0x1 as previously - with the more simple patch: end = (start >> MMU_SECTION_SHIFT) + (size >> MMU_SECTION_SHIFT) the value of end change: start >> 21 = 0, size >> 21 = 0 and end = 0x0 !!!
