arc: Remove common.h usage

2023-10-24T20:34:45+00:00

We can remove common.h from most cases of the code here, and only a few
places need an additional header instead.

reset: Remove addr parameter from reset_cpu()

2021-03-02T19:03:02+00:00

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)
    { ... }

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

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  at all, so
remove that include.

arc: emsdp/iotdk: Switch to DM_MMC

2019-11-01T13:45:40+00:00

Somehow EMSDP & IoT DK boards were skipped on ARC boads conversion
to DM MMC. So doing it now.

arc: Get rid of board-specific print_cpuinfo()

2018-12-03T11:26:26+00:00

Since we now do advanced CPU identification in
generic ARC code there's no need to have per-board
hardcoded data.

axs10x/emdk/hsdk/iot_dk: Implement board_mmc_getcd()

2018-10-12T12:14:41+00:00

So now we may detect MMC/SD-card existence and
instead of completely misleading message on missing card:
------------------------>8-----------------------
Loading Environment from FAT... Card did not respond to voltage select!
------------------------>8-----------------------

we now get very clear one:
------------------------>8-----------------------
Loading Environment from FAT... MMC: no card present
------------------------>8-----------------------

iot_dk: Save CPU clock value to gd->cpu_clk

2018-10-12T12:14:41+00:00

Since gd->cpu_clk is a global item we may once populate it from .dtb
ans use it then in other places like for printing CPU info etc.
