* reset: Remove addr parameter from reset_cpu()Harald Seiler2021-03-022-2/+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>
* common: Drop asm/global_data.h from common headerSimon Glass2021-02-024-0/+4
| | | | | | | | | | | | 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. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

* command: Remove the cmd_tbl_t typedefSimon Glass2020-05-182-13/+20
| | | | | | | | | | | | | 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>

| | | | | | | | | | | Use register intstead of static variable to store HSDK init status as we want to avoid the situation when we reload U-boot via MDB after previous init is done but HW reset (board reset) isn't done. So let's store the init status in unused register - CREG_CPU_0_ENTRY so status will survive after U-boot is reloaded via MDB.

* ARC: rework setting of ARC CPU specific compiler optionsEugeniy Paltsev2020-02-126-2/+30
| | | | | | | | | | | | | It's a very rare if at all existing occasion when ARC CPU template is used as is w/o any changes - in the end it's a beauty and competitive advantage of ARC cores to be tailored for a particular use-case - and so it doesn't make a lot of sense to offer template-based "-mcpu" selection. Given for each and every platform we end-up adding quite a few more flags it's logical to move "-mcpu" selection to platform's definition as well which we exactly do here.

* dm: core: Create a new header file for 'compat' featuresSimon Glass2020-02-051-0/+1
| | | | | | | | | | | | At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.
