Check all compatible strings on uart devices in powerpc

Summary:
Some device trees put "fsl,ns16650" first in the compatible list.  This causes
the probe code to choke, even though the device is compatible with ns16650, and
has it listed later in the tree.

Allow callers of OF_decode_addr to get the size of the found mapping. This

2016-02-16T15:18:12+00:00

will allow for code that uses the old fdt_get_range and fdt_regsize
functions to find a range, map it, access, then unmap to replace this, up
to and including the map, with a call to OF_decode_addr.

As this function should only be used in the early boot code the unmap is
mostly do document we no longer need the mapping as it's a no-op, at least
on arm.

Do not fail the low-level device probe simply because the kernel

2014-07-26T17:49:40+00:00

doesn't have support for the Z8530. Embedded PowerPC platforms
typically don't. Fail when the device class we actually need is
not present.

Make uart_cpu_powerpc work on both FDT and OFW systems. This is the last

Convert Freescale PowerPC platforms to FDT convention.

2010-07-11T21:08:29+00:00

The following systems are affected:

  - MPC8555CDS
  - MPC8572DS

This overhaul covers the following major changes:

  - All integrated peripherals drivers for Freescale MPC85XX SoC, which are
    currently in the FreeBSD source tree are reworked and adjusted so they
    derive config data out of the device tree blob (instead of hard coded /
    tabelarized values).

  - This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC,
    QUICC, UART, CFI.

  - Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire
    ocpbus(4) driver, which was based on hard-coded config data.

Note that world for these platforms has to be built WITH_FDT.

Fix serial console on Apple Xserve G5 by falling back to input-device-1

2009-07-23T12:51:27+00:00

if input-device is unavailable. The Xserve G5 defaults to using
screen/keyboard for output-device/input-device even if these are not
installed, and then falls back to serial ports at boot time.

Don't use pmap_kextact() when comparing bus handles for Book-E.

2009-04-08T22:19:39+00:00

We typically wire translation to devices with TLB1 entries and
pmap_kextract() does not know about those and returns 0.  This
causes false positives (read: all serial ports suddenly become
the console).

Add support for 64-bit PowerPC CPUs operating in the 64-bit bridge mode

Initial support for Freescale PowerQUICC III MPC85xx system-on-chip family.

2008-03-03T17:17:00+00:00

The PQ3 is a high performance integrated communications processing system
based on the e500 core, which is an embedded RISC processor that implements
the 32-bit Book E definition of the PowerPC architecture. For details refer
to: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPC8555E

This port was tested and successfully run on the following members of the PQ3
family: MPC8533, MPC8541, MPC8548, MPC8555.

The following major integrated peripherals are supported:

  * On-chip peripherals bus
  * OpenPIC interrupt controller
  * UART
  * Ethernet (TSEC)
  * Host/PCI bridge
  * QUICC engine (SCC functionality)

This commit brings the main functionality and will be followed by individual
drivers that are logically separate from this base.
