+Power Architecture CPU Binding
+Copyright 2013 Freescale Semiconductor Inc.
+
+Power Architecture CPUs in Freescale SOCs are represented in device trees as
+per the definition in ePAPR.
+
+In addition to the ePAPR definitions, the properties defined below may be
+present on CPU nodes.
+
+PROPERTIES
+
+ - fsl,eref-*
+ Usage: optional
+ Value type: <empty>
+ Definition: The EREF (EREF: A Programmer.s Reference Manual for
+ Freescale Power Architecture) defines the architecture for Freescale
+ Power CPUs. The EREF defines some architecture categories not defined
+ by the Power ISA. For these EREF-specific categories, the existence of
+ a property named fsl,eref-[CAT], where [CAT] is the abbreviated category
+ name with all uppercase letters converted to lowercase, indicates that
+ the category is supported by the implementation.

- Information about PowerPC Sound support
-=====================================================================
-
-Please mail me (Cort Dougan, cort@fsmlabs.com) if you have questions,
-comments or corrections.
-
-Last Change: 6.16.99
-
-This just covers sound on the PReP and CHRP systems for now and later
-will contain information on the PowerMac's.
-
-Sound on PReP has been tested and is working with the PowerStack and IBM
-Power Series onboard sound systems which are based on the cs4231(2) chip.
-The sound options when doing the make config are a bit different from
-the default, though.
-
-The I/O base, irq and dma lines that you enter during the make config
-are ignored and are set when booting according to the machine type.
-This is so that one binary can be used for Motorola and IBM machines
-which use different values and isn't allowed by the driver, so things
-are hacked together in such a way as to allow this information to be
-set automatically on boot.
-
-1. Motorola PowerStack PReP machines
-
- Enable support for "Crystal CS4232 based (PnP) cards" and for the
- Microsoft Sound System. The MSS isn't used, but some of the routines
- that the CS4232 driver uses are in it.
-
- Although the options you set are ignored and determined automatically
- on boot these are included for information only:
-
- (830) CS4232 audio I/O base 530, 604, E80 or F40
- (10) CS4232 audio IRQ 5, 7, 9, 11, 12 or 15
- (6) CS4232 audio DMA 0, 1 or 3
- (7) CS4232 second (duplex) DMA 0, 1 or 3
-
- This will allow simultaneous record and playback, as 2 different dma
- channels are used.
-
- The sound will be all left channel and very low volume since the
- auxiliary input isn't muted by default. I had the changes necessary
- for this in the kernel but the sound driver maintainer didn't want
- to include them since it wasn't common in other machines. To fix this
- you need to mute it using a mixer utility of some sort (if you find one
- please let me know) or by patching the driver yourself and recompiling.
-
- There is a problem on the PowerStack 2's (PowerStack Pro's) using a
- different irq/drq than the kernel expects. Unfortunately, I don't know
- which irq/drq it is so if anyone knows please email me.
-
- Midi is not supported since the cs4232 driver doesn't support midi yet.
-
-2. IBM PowerPersonal PReP machines
-
- I've only tested sound on the Power Personal Series of IBM workstations
- so if you try it on others please let me know the result. I'm especially
- interested in the 43p's sound system, which I know nothing about.
-
- Enable support for "Crystal CS4232 based (PnP) cards" and for the
- Microsoft Sound System. The MSS isn't used, but some of the routines
- that the CS4232 driver uses are in it.
-
- Although the options you set are ignored and determined automatically
- on boot these are included for information only:
-
- (530) CS4232 audio I/O base 530, 604, E80 or F40
- (5) CS4232 audio IRQ 5, 7, 9, 11, 12 or 15
- (1) CS4232 audio DMA 0, 1 or 3
- (7) CS4232 second (duplex) DMA 0, 1 or 3
- (330) CS4232 MIDI I/O base 330, 370, 3B0 or 3F0
- (9) CS4232 MIDI IRQ 5, 7, 9, 11, 12 or 15
-
- This setup does _NOT_ allow for recording yet.
-
- Midi is not supported since the cs4232 driver doesn't support midi yet.
-
-2. IBM CHRP
-
- I have only tested this on the 43P-150. Build the kernel with the cs4232
- set as a module and load the module with irq=9 dma=1 dma2=2 io=0x550

- Information about the Linux/PPC kernel images
-=====================================================================
-
-Please mail me (Cort Dougan, cort@fsmlabs.com) if you have questions,
-comments or corrections.
-
-This document is meant to answer several questions I've had about how
-the PReP system boots and how Linux/PPC interacts with that mechanism.
-It would be nice if we could have information on how other architectures
-boot here as well. If you have anything to contribute, please
-let me know.
-
-
-1. PReP boot file
-
- This is the file necessary to boot PReP systems from floppy or
- hard drive. The firmware reads the PReP partition table entry
- and will load the image accordingly.
-
- To boot the zImage, copy it onto a floppy with dd if=zImage of=/dev/fd0h1440
- or onto a PReP hard drive partition with dd if=zImage of=/dev/sda4
- assuming you've created a PReP partition (type 0x41) with fdisk on
- /dev/sda4.
-
- The layout of the image format is:
-
- 0x0 +------------+
- | | PReP partition table entry
- | |
- 0x400 +------------+
- | | Bootstrap program code + data
- | |
- | |
- +------------+
- | | compressed kernel, elf header removed
- +------------+
- | | initrd (if loaded)
- +------------+
- | | Elf section table for bootstrap program
- +------------+
-
-
-2. MBX boot file
-
- The MBX boards can load an elf image, and relocate it to the
- proper location in memory - it copies the image to the location it was
- linked at.
