* clk: select CLKDEV_LOOKUP from COMMON_CLKAhmad Fatoum2024-01-191-1/+0

| | | | | | | | | | | | | | | | | | | The Linux <linux/word-at-a-time.h> interface is used to optimize searching for bytes in strings by doing word-size comparisons. This will be used in the implementation of strscpy in a follow-up commit, so import the generic version here. A good overview on the interface is available at LWN[1]. Note that it discuss Linux v3.5. The asm-generic version imported here works also on little-endian and not only big-endian[2].

| | | | | | | | | | | | | | | Now that there are no longer any users of regmap.h in headers, let's switch all users in the source files to linux/regmap.h. That way, the only users of regmap.h whether directly or indirectly will be out-of-tree code, which will fail with an error if they are dependent on the old semantics of regmap_bulk_read and regmap_bulk_write. After a transitory period, we can then drop regmap.h.

* kvx: Add missing include/asm/mmu.hJules Maselbas2023-06-281-0/+8
| | | | | | | | | | | | | | | | | | | | | Since the rework of remap_range each architecture is expected to have the asm/mmu.h header, this wasn't the case for kvx, fix this. By default the KV3-1 cpu (as found in Coolidge SoC) starts with all memory uncached and MMU disabled. Data and instruction L1-caches are enabled very early during barebox start code, see arch/kvx/cpu/start.S, using the wfxl instruction to modify DCE and ICE (resp. Data and Instruction Cache Enable) bits in PS (Processor Status) of the system register file. The core MMU is not used by barebox, however there is a default mapping of the memory when the MMU is disabled where only the SMEM and DDR memory are cached and device-memory isn't.

| * | dma: rework dma_sync_single_for_*() interfaceDenis Orlov2023-06-061-6/+10
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, a lot of code handles dma_addr_t values as if they actually hold CPU addresses. However, this is not always true. For example, MIPS architecture requires an explicit conversion from the physical address space to some virtual address space segment to get a valid CPU-side pointer. Another issue is that DMA ranges that may be specified in a device tree will not work this way. To get from a virtual address to a dma handle and vice versa we need to add/subtract some offset, which is calculated from "dma-ranges" property. Only dma_map_single() was doing this, but dma_sync_single_for_*() also should. Improve the interface by adding 'struct device' as the first argument to the dma_sync_single_for_*(). This allows to do cpu_to_dma/dma_to_cpu() conversions in common code and call into arch-specific code with proper cpu-side addresses. To make things more clear, make the virtual address argument of those arch-side functions be properly represented with a void* type. Apply the required changes in device drivers that use the affected functions, making them pass the appropriate device pointer.

* / treewide: add MODULE_DEVICE_TABLE markersAhmad Fatoum2023-06-131-0/+1
|/ | | | | | | | | | | | | | | | Syncing device trees with Linux upstream can lead to breakage, when the device trees are switched to newer bindings, which are not yet supported in barebox. To make it easier to spot such issues, we want to start applying some heuristics to flag possibly problematic DT changes. One step towards being able to do that is to know what nodes barebox actually consumes. Most of the nodes have a compatible entry, which is matched by an array of of_device_id, so let's have MODULE_DEVICE_TABLE point at it for future extraction.

* kvx: add I-cache and D-cache synchronisationClement Leger2020-07-011-0/+18
| | | | | | | | | | | Before booting, we must make sure the I-cache is synchronized with the D-cache to execute loaded instructions. In order to do that, add a function which execute a fence to ensure every memory accesses have been committed out of processor pipeline to memory and then invalidate I-cache to reload from memory.

| * kvx: do not include empty <config.h>Masahiro Yamada2020-05-183-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <config.h> is per-board config file, which is only allowed for old boards. For new boards, the top Makefile creates an empty include/config.h kvx does not have config.h, so #include <config.h> is useless. Also, remove meaningless board-$(CONFIG_GENERIC).
