The page_layout API returns pointers to kernel memory and is not
exposed to user mode. This is fine for flash_get_page_count()
and flash_get_page_info APIs since these copy the values, but some
redesign work will be needed to get flash_page_foreach() working in
user mode since we do not want the callback running in a privileged
state.
Due to the way that (even unimplemented) system call prototypes are
generated, the definition of struct flash_pages_info needed to be
moved outside of the #ifdef.

Straightforward conversion for adc_enable/disable.
adc_read() uses a sequence table, which points to an array
of struct adc_seq_entry, each element pointing
to memory buffers. Need to validate all of these as being readable
by the caller, and the buffers writable.

i2c actually only has two entry points into the driver,
i2c_configure and i2c_transfer. All the other APIs are derived
from these.
All derived APIs now just call i2c_transfer() with appropriate args.
The handler for i2c_transfer() needs to examine the message array
and validate all the buffers involved depending on whether we are
reading or writing to them.

In bind_default(), a local variable is passed to find_available_port().
However, the port number is unpredictable as it's not initialized and
will be used directly if not zero. This will lead to problems if the
port number is already used.
This patch makes find_available_port() always returns an available port
regardless of the port number in the sockaddr parameter.

The Designware FIFO is filled in units of 32 bit words, but the buffer
we are passed is not guaranteed to be a multiple of 4 bytes long, nor
aligned on a 4-byte boundary. So in theory we are reading 0-3 bytes
of unused garbage from the end of the array.
That's currently benign on supported platforms with this hardware,
which all support misaligned reads. But not all do. And the incoming
arrival of memory protection opens the possibility that those extra
bytes would cross a protection boundary and cause a crash or security
bug.
Do this right.
(Note that this is fixed to little endian byte order. The Designware
databook is frustratingly silent on the endianness it expects, but
existing hardware I can see is definitely LE and I see a few spots in
the Linux dwc2 driver that likewise assume LE).

The designware hardware in dedicated FIFO mode (which is all we
support right now for lack of shared-FIFO hardware) has one hardware
FIFO per IN (i.e. transmit) endpoint. But it doesn't assign them on
its own, it's the drivers responsibility to populate the TxFNum field
of the DIEPCTL registers with integer indices corresponding to the
desired FIFO.
We weren't doing that, which meant that all IN endpoints were sharing
the same FIFO zero which is supposed to be dedicated to EP0 control
transfers. The net effect is that sometimes outbound transfers would
be corrupted, showing data from the wrong endpoint. More often that
not this would leak from control transfers over to the
higher-bandwidth bulk endpoints of the application, but occasionally
you'd see a control transfer itself get borked and the USB device
would glitch.
Get this right and set the FIFOs properly.

This reverts commit 1da0a9eebd.
The workaround caused a severe performance penalty, and only worked
for USB packets of 4-15 bytes in length (16+ byte packets weren't
subject to the hardware bug). Single-byte packets (very common for
cdc_acm serial port transfers) would still be duplicated sometimes.
The upcoming DMA implementation does not share the performance
penalty, and also is not subject to the bug for those sizes of packets
(though it DOES still have a problem with single-byte packets!).

There is no particular reason this spot in usb_dw_tx() cannot be
reached by racing threads on the same endpoint, though existing API
usage in the tree is all unithreaded. The FIFO state read at the top
of the function must still be true at the bottom or else the packet
byte count will be corrupt.
Also, as described in an existing comment, the databook has some
scary-sounding warnings about access to the registers during FIFO
operations, even if they "should" be on separate endpoints and
unrelated.

This rework commit 77b8f5c1f6
Comparing it to BT IPSP is a the wrong comparison: BT IPSP does specify
6lo/ipv6 for it to work. Whereas 802.15.4 does not.
Instead of selecting 6lo from 802.15.4's Kconfig, let's do the reverse
way. If the user enabled 802.15.4 and IPv6 as well (to which 6lo
depends on), then 6lo is enabled by default as using IPv6 on 15.4
without it does not make much sense.

Intention of CONFIG_BOOT_DELAY is to delay booting of system for certain
time. Currently it is only delaying start of _main thread as delay is
created using k_sleep. This leads to putting _main thread into timeout
queue and continue kernel boot. This is causing some of undesirable
effects in some of test Automation usecase.
This patch changes k_sleep to k_busy_wait which result in delay in OS
boot instead of delaying start of _main.
