2021-07-28arm64: Update memcpy_{from, to}io() helpersPatrice Chotard1-0/+1
At early U-Boot stage, before relocation, MMU is not yet configured and disabled. DDR may not be configured with the correct memory attributes (can be configured in MT_DEVICE instead of MT_MEMORY). In this case, usage of memcpy_{from, to}io() may leads to synchronous abort in AARCH64 in case the normal memory address is not 64Bits aligned. To avoid such situation, forbid usage of normal memory cast to (u64 *) in case MMU is not enabled.

2021-03-02reset: Remove addr parameter from reset_cpu()Harald Seiler1-2/+2
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>
2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass1-1/+1
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>

2019-12-02common: Move ARM cache operations out of common.hSimon Glass1-0/+24
These functions are CPU-related and do not use driver model. Move them to cpu_func.h Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com> Reviewed-by: Tom Rini <trini@konsulko.com>
2019-12-02common: Move some cache and MMU functions out of common.hSimon Glass1-0/+8
These functions belong in cpu_func.h. Another option would be cache.h but that code uses driver model and we have not moved these cache functions to use driver model. Since they are CPU-related it seems reasonable to put them here. Move them over. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
