cb0efb3f8e Fix PCIe hardware swap configuration for Netlogic XLP
The last 12 bits of the limit registers have to be set to 1. These
bits are not significant in bridge BARs and are 0 on read, but the
bits are valid in the swap limit register and needs to be set.

8374f23681 Resource allocation for XLP SoC SDHCI slots
The on-chip SD slots do not have PCI BARs corresponding to them, so
this has to be handled in the custom SoC memory allocation.

Provide memory resource for rids corresponding to BAR 0 and 1 in
the custom allocation code.

0ec682f566 Update memory and resource allocation code for SoC devices
The XLP on-chip devices have PCI configuration headers, but some of the
devices need custom resource allocation code.
- devices with no MEM/IO BARs with registers in PCIe extended reg
  space have to be handled in memory resource allocation
- devices without INTPIN/INTLINE in PCI header can be supported
  by having these faked with a shadow register.
- Some devices does not allow 8/16 bit access to the register space,
  he default bus space cannot be used for these.

Subclass pci and override attach and resource allocation methods to
take care of this.

Remove earlier code which did this partially.

126e29ce5f XLP UART code udpate.
Move XLP PCI UART device to sys/mips/nlm/dev/ directory.  Other
drivers for the XLP SoC devices will be added here as well.

speed and IO frequency.

4d0abc074b Support for EEPROM and CPLD on XLP EVP boards.
On XLP evaluation platform, the board information is stored
in an I2C eeprom and the network block configuration is available
from a CPLD connected to the GBU (NOR flash bus). Add support
for both of these.

96376fdd3f XLP PCIe code update.
- XLP supports hardware swap for PCIe IO/MEM accesses. Since we
  are in big-endian mode, enable hardware swap and use the normal
  bus space.
- move some printfs to bootverbose, and remove others.
- fix SoC device resource allocation code
- Do not use '|' while updating PCIE_BRIDGE_MSI_ADDRL
- some style fixes

195d122172 o) Use ABI, not ISA_* options, to determine whether to compile bits if libkern
required for the ABI the kernel is being built for.
   XXX This is implemented in a kind-of nasty way that involves including source
       files, but it's still an improvement.
o) Retire ISA_* options since they're unused and were always wrong.

ac2071063e Remove platform APIs which are not used by any code and which had only stub
implementations or no implementation on all platforms.

Some of these functions might be good ideas, but their semantics were unclear
given the lack of implementation, and an unlucky porter could be fooled into
trying to implement them or, worse, being baffled when something like
platform_trap_enter() failed to be called.

17e14c6132 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.
  Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.
  Discussed with: jhb
- Also while at it, use __FBSDID.

86c9f7a0f6 Do dcache flush on CPU core before enabling threads.
The dcache flush has to be done using the core control registers before
splitting the L1D cache by enabling the hardware threads.

Also replace .word calls for mfcr/mtcr with a C macro.

63a97a16ab Rearrange XLP configuration files.
Create std.XLP for configuration options, which is included by the

Also move uart and pci to mips/nlm/std.xlp since all XLP configurations
needs these devices.

566ec163bd MIPS XLP platform code update.
* Update the hardware access register definitions and functions to bring
  them in line with other Netlogic software.
* Update the platform bus to use PCI even for on-chip devices. Add a dummy
  PCI driver to ignore on-chip devices which do not need driver.
* Provide memory and IRQ resource allocation code for on-chip devices
  which cannot get it from PCI config.
* add support for on-chip PCI and USB interfaces.
* update conf files, enable pci and retain old MAXCPU until we can support
  >32 cpus.
