This builds fine with FAST_DEPEND but the mkdep method requires that
include/ generates the headers during 'make depend' so the subsequent
directories can find them when running mkdep.

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.

If the output object is not an ELF file, choose an arbitrary ELF format
for the intermediate file. srec, ihex and binary formats are independent
of class, endianness and machine type so these choices do not affect the
output.

for now and may be revised when other drivers start using multipass
feature.
This is needed after an update of Linux dts files done in r295436.
(1) The channel mask is get from "brcm,dma-channel-mask" property of
dma node, and if not provided, from "broadcom,channels" property.
(2) Consequently, sdhci driver does not allocate any specific channel.
(3) Use CS_RESET bit for initial channel reset.

POSIX.1-2008 requires that successful completion simply return a
non-negative integer. We have regularly returned a constant value.
Another, equally valid, implementation convention implies returning
the number of bytes written.
Adopt this last convention to be in line with what Apple's libc
does. POSIX also explicitly notes:
Note that this implementation convention cannot be adhered to for strings
longer than {INT_MAX} bytes as the value would not be representable in the
return type of the function. For backwards-compatibility, implementations
can return the number of bytes for strings of up to {INT_MAX} bytes, and
return {INT_MAX} for all longer strings.
Developers shouldn't depend specifically on either convention but
the change may help port software from Apple.

This patch allows the newly imported INTRNG code to be built without necessarily
having FDT support in the kernel. This may be useful for some MIPS platforms
that wish to move to INTRNG, but not to FDT at the same time.
Basically all the code is already within ifdef's where FDT is concerned,
it's just the headers that aren't.

This patch comes from Dave Jiang's Linux tree, davejiang/ntb. It hasn't
been accepted into Linus' tree, so I do not have an authoritative SHA1
to point at. Original commit log:
=====================================================================
A hardware errata causes the NTB to hang when heavy bi-directional
traffic in addition to the usage of BAR0/1 (where the registers reside,
including the doorbell registers to trigger interrupts).
This workaround is only available on Haswell and Broadwell platform.
The workaround is to enable split BAR in the BIOS to allow the 64bit
BAR4 to be split into two 32bit BAR4 and BAR5. The BAR4 shall be pointed
to LAPIC region of the remote host. We will bypass the db mechanism and
directly trigger the MSIX interrupts. The offsets and vectors are
exchanged during transport scratch pad negotiation. The scratch pads are
now overloaded in order to allow the exchange of the information. This
gets around using the doorbell and prevents the lockup with additional
pcode changes in BIOS.
Signed-off-by: Dave Jiang <dave.jiang@intel.com>
=====================================================================
Notable changes in the FreeBSD version of this patch:
* The MSIX BAR is configurable, like hw.ntb.b2b_mw_idx (msix_mw_idx).
The Linux version of the patch only uses BAR4.
* MSIX negotiation aborts if the link goes down.

The I/OAT HW reset process may sleep, so it is invalid to perform a
channel reset from the software interrupt thread.
