Annotated Snippet

IBM Akebono board device tree
=============================

The IBM Akebono board is a development board for the PPC476GTR SoC.

0) The root node

   Required properties:

   - model : "ibm,akebono".
   - compatible : "ibm,akebono" , "ibm,476gtr".

1.a) The Secure Digital Host Controller Interface (SDHCI) node

  Represent the Secure Digital Host Controller Interfaces.

  Required properties:

   - compatible : should be "ibm,476gtr-sdhci","generic-sdhci".
   - reg : should contain the SDHCI registers location and length.
   - interrupts : should contain the SDHCI interrupt.

1.b) The Advanced Host Controller Interface (AHCI) SATA node

  Represents the advanced host controller SATA interface.

  Required properties:

   - compatible : should be "ibm,476gtr-ahci".
   - reg : should contain the AHCI registers location and length.
   - interrupts : should contain the AHCI interrupt.

1.c) The FPGA node

  The Akebono board stores some board information such as the revision
  number in an FPGA which is represented by this node.

  Required properties:

   - compatible : should be "ibm,akebono-fpga".
   - reg : should contain the FPGA registers location and length.

1.d) The AVR node

  The Akebono board has an Atmel AVR microprocessor attached to the I2C
  bus as a power controller for the board.

  Required properties:

   - compatible : should be "ibm,akebono-avr".
   - reg : should contain the I2C bus address for the AVR.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
