The changes are to:
* Use contigmalloc/contigfree which handling microcode buffer
* Use a different buffer to send microcode to each engine
* Swap microcode in little-endian compilation
* Fix freeback message queue id field
* Simplify xlp_get_rsa_opsize() to remove unnecessary checks
* Fix NULL check after use in xlp_free_cmd_params()
* Do better error handling when the hardware returns error
* Fix error codes in few cases

Updates to the Netlogic XLP on-chp RSA block driver. The changes are
to follow style(9) guidelines, to improve readability and to remove
unnecessary initialization.
No changes to logic have been introduced by this commit.

Changes are to
- update board and network interface detection logic
- fix reading onboard CPLD in little-endian config
- print NAE frequency conrrectly for Bx chips
- update XAUI config to disable Rx/Tx until interface is up

Switch eventtimers(9) from using struct bintime to sbintime_t.
Even before this not a single driver really supported full dynamic range of
struct bintime even in theory, not speaking about practical inexpediency.
This change legitimates the status quo and cleans up the code.
The changes are:
- the microcore code loaded into the NAE has to be byteswapped
in LE
- the descriptors in memory for a P2P NAE descriptor has to be
byteswapped in LE
- the m_data pointer is already cacheline aligned, so the
unnecessary m_adj to cacheline size can be removed
- fix mask used to obtain physical address from the Tx freeback
descriptor
- fix a compile error in code under #ifdef

Update MDIO reset code to support Broadcom XLP B1 revisions.

called after nlm_xlpge_init.

Support few more versions of board firmware. In case the security
block is disabled, enable it at boot. Also increase the excluded
memory region to cover the area used by the firmware to initialize
devices.
Update the function xlp_pcib_hardware_swap_enable() to do nothing
when BYTE_ORDER is not BIG_ENDIAN. PCIe hardware swap is not requred
in little-endian mode as the endianness matches that of CPU.
r239274 added support for ranges. Update XLP DTS to provide the correct
range parameter for the XLP SoC bus. Also fix bus_space_map method
for XLP bus space.

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.
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.
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.
Move XLP PCI UART device to sys/mips/nlm/dev/ directory. Other
drivers for the XLP SoC devices will be added here as well.
Update uart_cpu_xlp.c and uart_pci_xlp.c use macros for uart port,
speed and IO frequency.
Features:
- network driver for the four 10G interfaces and two management ports
on XLP 8xx.
- Support 4xx and 3xx variants of the processor.
- Source code and firmware building for the 16 mips32r2 micro-code engines
in the Network Accelerator.
- Basic initialization code for Packet ordering Engine.

[refactored and fixed up for style by jchandra]
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.
Support for the Security and RSA blocks on XLP SoC. Even though
the XLP supports many more algorithms, only the ones supported
in OCF have been added.

- 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

* Use interrupts to wakeup message handling threads on 3XX
* Update PIC code, read interrupt information from PCI header instead
of using fixed values.
* Update PCI interrupt handling for the PIC change.
* Update code for getting chip frequency, new code support XLP 3XX

Create std.XLP for configuration options, which is included by the
conf files. The files XLP, XLPN32 and XLP64 will have mostly ABI related
options.
Also move uart and pci to mips/nlm/std.xlp since all XLP configurations
needs these devices.
