 ## Enforcement
 
 Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at
-conduct@zephyrproject.org. Reports will be received by the Chair of the Zephyr
-Governing Board, the Zephyr Project Director (Linux Foundation), and the Zephyr
-Project Developer Advocate (Linux Foundation). You may refer to the [Governing
-Board](https://zephyrproject.org/governing-board/) and [Linux Foundation
-Staff](https://zephyrproject.org/staff/) web pages to identify who are the
-individuals currently holding these positions.
-All complaints will be reviewed and investigated promptly and fairly.

+project team is obligated to maintain confidentiality with regard to the
+reporter of an incident.  Further details of specific enforcement policies may
+be posted separately.
 
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.

-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series of
-actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or permanent
-ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior, harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within the
-community.
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.

-	  Relocates the rom_start region containing the boot-vector data and
-	  irq vectors to the region specified by configurations:
-	  ROMSTART_REGION_ADDRESS and ROMSTART_REGION_SIZE
-
-	  This is useful for the Linux Remoteproc framework that uses the elf-loader
-	  such that it is able to load the correct boot-vector (contained in rom_start)
-	  into the correct memory location independent of the chosen zephyr,flash
-	  ROM region.
-
-	  Most SOCs include an alias for the boot-vector at address 0x00000000
-	  so a default which might be supported by the corresponding Linux rproc driver.
-	  If it is not, additionnal options allows to specify the addresses.
-
-	  In general this option should be chosen if the zephyr,flash chosen node
-	  is not placed into the boot-vector memory area.
-
-	  While this aims at generating a correct zephyr.elf file, it has the side
-	  effect of enlarging the bin file. If the zephyr.bin file is used to boot the
-	  secondary core, this option should be disabled.
-
-	  Example:
-		on IMX7D, the chosen zephyr,flash can be OCRAM/OCRAM_S/TCM/DDR memories
-		for code location. But the boot-vector must be placed into OCRAM_S for the
-		CORTEX-M to boot (alias 0, real 0x00180000/32K available).

-
-		  A default value of 0x00000000 might work in most cases as SOCs have an alias
-		  to the right memory region of the boot-vector.
-
-		  Examples:
-		  -IMX7D the boot-vector is OCRAM_S (0x00180000, aliased at 0x0).

-		  -IMX8MN the boot-vector is ITCM (0x007E0000, aliased at 0x0).
