Timers are based off timeouts now, which can only be enabled when the
system clock is enabled. So the three are really just one setting now.
Keep the NANO_TIMERS and NANO_TIMEOUTS around for now until all
middleware that rely on them is updated. They are always enabled when
SYS_CLOCK_EXISTS is enabled.

Packets sent out through net_tx_fiber go through psock_send() where
they wait for data_is_sent_and_acked() to process them.
data_is_sent_and_acked() looks at the underlying connection's
MSS (maximum segment size) before putting them on the wire through
uip_send(). The trouble is that that linkage between the outgoing
buffer and the connection hasn't been established at the point
data_is_sent_and_acked() is called--this normally happens through
a call to uip_set_conn().
So data_is_sent_and_acked() fetches an invalid connection handle
and makes its choice using an arbitrary MSS. In my particular case,
this arbitrary value was 0, and so packets weren't being sent out.

ARC interrupts can be either level or pulse.
Level interrupts remain asserted until the interrupt service routine
clears the interrupt at the peripheral. This is the default and most
common case.
Pulse interrupts have an extra flip-flop that converts a pulse to a
level. The ARC auto-clears this level as the interrupt service routine
is entered. As such, an interrupt handler for a pulse interrupt need
not clear the interrupt.
It is the rare device that uses pulse interrupts.
Nothing currently calls this inline function so ARC interrupts are
LEVEL by default.

Simplified some documentation, removing inconsistencies and making
it easier to understand by separating PM infrastructure areas and
soc specific components that implement the hooks.
Removed the DEVICE_SUSPEND_ONLY policy as it is redundant and
causes high complexity in the flow. It is also not practical
to use it because it was meant to be used without doing CPU or SOC
low power state operations. This means it would do device PM
operations in the ISR of the system timer used by the scheduler.
This can disrupt the scheduler time.
Added a check of a flag around the notification sent from the ISR
of the wake event and created APIs to set/clear it. This will
allow disabling the notification when not needed from
_sys_soc_suspend().

Binutils ld has an annoying misfeature (apparently a regression from a
few years ago) that alignment directives (and alignment specifiers on
symbols) apply only to the runtime addresses and not, apparently, to
the load address region specified with the "AT>" syntax. The net
result is that by default the LMA output ends up too small for the
addresses generated in RAM. See here for some details:
https://sourceware.org/ml/binutils/2013-06/msg00246.htmlhttps://sourceware.org/ml/binutils/2014-01/msg00350.html
The required workaround/fix is that AFAICT any section which can have
inherit a separate VMA vs. LMA from a previous section must specify an
"ALIGN_WITH_INPUT" attribute. Otherwise the sections will get out of
sync and the XIP data will be wrong at runtime.
No, I don't know why this isn't the default behavior.
A further complexity is that this feature only works as advertised
when the section is declared with the "AT> region" syntax after the
block and not "AT(address)" in the header. If you use the header
syntax (with or without ALIGN_WITH_INPUT), ld appears to DOUBLE-apply
padding and the LMA ends up to big. This is almost certainly a
binutils bug, but it's trivial to work around (and the working syntax
is actually cleaner) so we adjust the usage here.
Note finally that this patch includes an effective reversion of commit
d82e9dd9 ("x86: HACK force alignment for _k_task_list section"), which
was an earlier workaround for what seems to be the same issue.

To avoid extra logic in code that creates net_buf fragment lists, make
it possible to pass a NULL pointer as the head net_buf when there are
no previous buffers. Before this change the code would look like this:
if (head) {
net_buf_frag_add(head, buf);
} else {
head = net_buf_ref(buf);
}
After the patch the code can simply do:
head = net_buf_frag_add(head, buf);
This will then do the right thing regardless if head is NULL or
non-NULL.
