20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
These changes were obtained by running a script  created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:

1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
   #define X Y)
3. Check if that name is also the name of a Kconfig option
   3.a If it is, then do nothing
   3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
       has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
   (.c, .h, .ld)

Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.

Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

This patch introduce version which fixes following bug:

It was possible to erase slot 1 while it stores confirmed image
while ongoing test run - this is unwanted behavior which allow
to even brick remote device accidentally.
This patch add check for such case of test run etc.
This also aligns condition required for erase command
execution to similar as upload command requires.

8cf8db3a73 Kconfig: Use a short, consistent style for prompts
Consistently use

    config FOO
            bool/int/hex/string "Prompt text"

instead of

    config FOO
            bool/int/hex/string
            prompt "Prompt text"

(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).

The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.

Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/
how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some
of the rarer variations had to be converted manually.

d1684a83a4 Kconfig: Clean up some symbol definitions
- Remove redundant 'n' defaults. 'n' is the default value for bool
  symbols.

  This makes the auto-generated documentation clearer as well: You get
  "implicitly defaults to n" instead of
  "- n if <propagated dependencies>".

- Shorten

      <type>
      prompt "foo"

  to

      <type> "foo"

  This works for all types, not just bool.

- Various formatting nits.

17b64bafae ext: Import OpenAMP for IPC
Origin:
   https://github.com/OpenAMP/open-amp

Status:
   de361adee09cd31793c60218a0ec49bc307a7410 [v2018.04]

   When we import open-amp we removed the apps dir to reduce the amount
   of code imported.

Purpose:
   IPC layer that implements rpmsg communication between cores.

Description:

This repository is the home for the Open Asymmetric Multi Processing
(OpenAMP) framework project. The OpenAMP framework provides software
components that enable development of software applications for
Asymmetric Multiprocessing (AMP) systems. The framework provides the
following key capabilities.

* Provides Life Cycle Management, and Inter Processor Communication
  capabilities for management of remote compute resources and their
  associated software contexts.
* Provides a stand alone library usable with RTOS and Baremetal software
  environments
* Compatibility with upstream Linux remoteproc and rpmsg components
* Following AMP configurations supported:
  a. Linux master/Generic(Baremetal) remote
  b. Generic(Baremetal) master/Linux remote
* Proxy infrastructure and supplied demos showcase ability of proxy on
  master to handle printf, scanf, open, close, read, write calls from
  Bare metal based remote contexts.

Dependencies:
   libmetal (https://github.com/OpenAMP/libmetal) - provides HAL layer
   between OpenAMP and RTOS or OS environment.

   https://github.com/OpenAMP/open-amp/

Status:
   606c31438025b9fb1515dace1c642d5835d8d33c [v2018.04]

   When we import libmetal we removed the tests/ and examples/ dir to
   reduce the amount of code imported.

Purpose:
   HAL abstraction layer used by open-amp

Description:
   Libmetal provides common user APIs to access devices, handle device
   interrupts and request memory across the following operating
   environments:

   * Linux user space (based on UIO and VFIO support in the kernel)
   * RTOS (with and without virtual memory)
   * Bare-metal environments

Dependencies:
   Depends on Zephyr itself as it utilizes Zephyr's APIs to provide an
   abstraction to open-amp.

This is just a dumb removal. I did not try to guess the intent of each
select.

This value allows to set max payload length of a TLS protocol
message, and passed thru to mbedTLS as MBEDTLS_SSL_MAX_CONTENT_LEN
setting. The only safe value is 16384, which translates to 32KB
of RAM required just for mbedTLS input/output buffers. Any other
value can be configured *only* per a particular application
(e.g. knowing that it won't pass more than spefific amount of
data at once and/or won't connect to a server with a long cert
chain). Previosuly, we had quite an adhoc and inflexible config
with random values for that setting, based on protocol.

Note that while the safe value is 16384, "backward compatible"
default of 1500 is used (good for DTLS on the other hand).

42680b07af mbedtls: Switch default MBEDTLS_CFG_FILE to config-mini-tls1_2.h
The previous default, "config-threadnet.h", is more or less arbitrary
choice made in a commit 312def2c78 1.5 years ago. In particular,
it's not related to Thread support in Zephyr per se (there was no
such support at that time).

It doesn't make sense to have a default intended for a particular,
not widely used (yet) protocol. Instead, the default should work
out of the box with a contemporary widely deployed arrays of TLS
servers, which are HTTPS server. config-mini-tls1_2.h works with
https://google.com, and by extension, with many other servers on
the Internet.

So, have that as the default, and let applications with special
needs to override that to what they need.

CONFIG_MBEDTLS means you are using MBEDTLS
CONFIG_MBEDTLS_BUILTIN means you are using a built-in MDEDTLS

implementation when MBEDTLS is enabled.

Tested by opening xconfig and observing that when MBEDTLS was enabled,
BUILTIN was automatically enabled, and a radio-button interface
existed to change the implementation.

2fc554b8fc crypto: config: config-coap: add CONFIG for setting max content length
The CoAP samples use an MBEDTLS config "config-coap.h" which could be
re-used by the LwM2M sample, except that most servers use a larger
maximum content length setting of 1500 bytes.

Let's add a CONFIG to set this for users of the CoAP lib and set the
CONFIG value for the samples to the 256 size currently used.

3a5ca91f28 crypto: Update TinyCrypt to 0.2.8
Version 0.2.8 of this library has been released on Aug 29, and this
patch updates the library from version 0.2.7.  A summary of changes
is available at the official repository at:

    https://github.com/01org/tinycrypt/releases/tag/v0.2.8

A number of the changes we already had in tree, so the import to sync
with v0.2.8 is pretty minor.
