Previous SAM E70 HAL version was patched by commit 4dcfc8706 ("Add
missing interrupt number definitions") to add missing interrupt
definitions for SAM GMAC Priority Queues. This has been fixed in the
latest HAL by using a slightly different name. This patch updates the
driver accordingly.

off_t is int with the minimal libc and long with the newlib libc. The
log messages are assuming that off_t is int, therefore this causes
warnings when building with newlib.
Fix that by casting the offset to the "longer" type, ie long.

Every now and then the 100ms delay for collecting IMEI data from the

During development of the WNC-M14A2A modem driver, I felt like the
initialization took too long to make the user wait. However, due
to the addition of other drivers such as OpenThread where delays
during startup are noticable, the modem startup time isn't so bad.
Let's remove the delay work which allows Zephyr to startup before
the modem is fully initialized.
NOTE: This also fixes a long standing bug where samples using the
modem would never know when it was ready (without waiting for the
interface up event). This change makes it always ready once the
sample starts.

Atmel SAM Ethernet module is using a scatter-gather technique to
exchange data with the Ethernet driver. To communicate the location
of the data buffers the driver sets-up a so called descriptor list. This
is effectively a place in RAM containing a sequence of 32-bit words
representing buffer location and its status.
Currently the cache coherency is handled using cache clean or
invalidate. Unfortunately this strategy only works correctly when the
corresponding data size is a multiple of the cache line. This is not
the case here and might lead to data loss or corruption.
Instead of using cache operations, this patch moves the descriptor
listed to the recently added non-cached memory region, as recommended by
ATMEL. A data synchronisation barrier is still required for writes, as
the non-cached memory is defined with TEX=1, i.e. it is not strongly
ordered. The descriptor lists alignment can be decreased to 4 bytes, as
required by the SAM Ethernet module.
The RX/TX buffer are left unchanged, still managed by cache operations.

The SAM E70 GMAC ethernet driver reference a packet with net_pkt_ref()
when queueing a packet, and unreference it with net_pkt_unref() in the
ISR when it has been fully sent.
The call to net_pkt_ref() is done just after re-enabling the
interruptions, so there is however a small race condition that might
cause the packet to be unreference before being referenced. This is
only theoretical and has not been seen in practice.
Fix that by moving the call to net_pkt_ref() just before re-enabling
the interruptions.

For some reason, there was sequence like:
1. Get size of RX packet.
2. Allocate pkt buffer.
3. Check if the size of RX packet is too large, then deallocate pkt
buffer and error out.
Instead, reorder operations to check size before allocating buf.

The OpenISA RV32M1 SoC has four CPU cores. Two of these are RISC-V
32-bit cores, which are named "RI5CY" and "ZERO-RISCY". (The other two
cores are ARM Cortex-M0+ and -M4.) This patch adds basic SoC
enablement for the RISC-V cores:
- basic dtsi, to be extended as additional drivers are added
- SoC definition in soc/riscv32/openisa_rv32m1 for RI5CY / ZERO-RISCY
- system timer driver for RI5CY, based on LPTMR0 peripheral
The timer driver will be generalized a bit soon once proper
multi-level interrupt support is available.
Emphasis is on supporting the RI5CY core as the more capable of the
two; the ZERO-RISCY SoC definitions are a good starting point, but
additional work setting up a dtsi and initial drivers is needed to
support that core.

Some extensions to the multi-level interrupt controller are required
to support SoCs with more than four level 2 interrupt "aggregators".
Extend existing support to allow at most 8 level 2 or level 3
aggregators. Use Kconfig macro templates to cut down on boilerplate.
Try to clarify some aspects of the Kconfig help while we're at it, and
change the type of options which count things or are table offsets
from "hex" to "int", so that the generated .config is easier to read.
Finally, make some improvements to gen_isr_tables.py while we are
here. In particular, move some assignments around to cut down on
duplicated work, don't check for symbols we know must exist, and
improve the debug logging output's readability.
