m68k: 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.

arch: m68k: Introduce trivial PIT based timer

2023-04-15T19:36:07+00:00

The QEMU emulation of m68k does not support DMA timer, the only
timer that is supported is the PIT timer. Implement trivial PIT
timer support for m68k.

arch: m68k: Use existing CONFIG_MCFTMR instead of CFG_MCFTMR

2023-04-15T19:36:07+00:00

There is an existing CONFIG_MCFTMR Kconfig symbol,
use it and drop all other instances of CFG_MCFTMR.
This duality is likely a result of bogus conversion
to Kconfig.

m68k: rename CONFIG_MCFTMR to CFG_MCFTMR

2023-03-15T00:41:57+00:00

This is not a Kconfig option so changing to _CFG.

global: Finish CONFIG -> CFG migration

2023-01-20T17:27:24+00:00

At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks.  Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

cyclic: Use schedule() instead of WATCHDOG_RESET()

2022-09-18T08:26:33+00:00

Globally replace all occurances of WATCHDOG_RESET() with schedule(),
which handles the HW_WATCHDOG functionality and the cyclic
infrastructure.

allow opting out of WATCHDOG_RESET() from timer interrupt

2021-04-27T06:28:07+00:00

Having WATCHDOG_RESET() called automatically from the timer interrupt
runs counter to the idea of a watchdog device - if the board runs into
an infinite loops with interrupts still enabled, the watchdog will
never fire.

When using CONFIG_(SPL_)WDT, the watchdog_reset function is a lot more
complicated than just poking a few SOC-specific registers - it
involves accessing all kinds of global data, and if the interrupt
happens at the wrong time (say, in the middle of an WATCHDOG_RESET()
call from ordinary code), that can end up corrupting said global data.

Allow the board to opt out of calling WATCHDOG_RESET() from the timer
interrupt handler by setting CONFIG_SYS_WATCHDOG_FREQ to 0 - as that
setting is currently nonsensical (it would be compile-time
divide-by-zero), it cannot affect any existing boards.

Add documentation for both the existing and extended meaning of
CONFIG_SYS_WATCHDOG_FREQ.

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.
