2c96ac7a39 Use the new(-ish) CP15_SCTLR macro to generate system control reg accesses
where possible.  In the places that doesn't work (multi-line inline asm,
and places where the old armv4 cpufuncs mechanism is used), annotate the
accesses with a comment that includes SCTLR.  Now a grep -i sctlr can find
all the system control register manipulations.

No functional changes.

d9c9c81c08 sys: use our roundup2/rounddown2() macros when param.h is available.
rounddown2 tends to produce longer lines than the original code
and when the code has a high indentation level it was not really
advantageous to do the replacement.

This tries to strike a balance between readability using the macros
and flexibility of having the expressions, so not everything is
converted.

fda16d46fe ARM: Teach LINUX_BOOT_ABI to recognize DT blob.
This allow us to boot FreeBSD kernel (using uImage encapsulation) directly
from U-boot using 'bootm' command or by Android fastboot loader.
For now, kernel uImage must be marked as Linux, but we can add support for
FreeBSD into U-Boot later.

dec4873723 Fix fallout from r292180 (Dec 2015)... ensure that every driver which has
a DRIVER_MODULE() referencing mmc_driver has a MODULE_DEPEND() on mmc.  This
is because the kernel linker only searches for symbols in dependent modules,
so loading sdhci_pci (and other bus-flavors of sdhci) would fail when mmc
was not compiled into the kernel (even if you hand-loaded mmc first).

(Thanks to jilles@ for providing the vital clue about the kernel linker.)

7915adb560 Introduce a RMAN_IS_DEFAULT_RANGE() macro, and use it.
This simplifies checking for default resource range for bus_alloc_resource(),

This is part of, and related to, the migration of rman_res_t from u_long to

2dd1bdf183 Convert rman to use rman_res_t instead of u_long
Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources.  For
now, this is still compatible with u_long.

This is step one in migrating rman to use uintmax_t for resources instead of
u_long.

Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.

This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

750e48d766 Fix the handling of the "PDC write transfer length" erratum for at91. The
problem affects revision 1xx hardware as well as later versions.  Also, the
recommended workaround is to set the PDC count register for a 12-byte
transfer when the actual size is less than that, but there is no need to
extend or zero-out the data buffer, because the blklen register contains
the real transfer size and only that many bytes will be transferred.

Also add a sysctl to turn debugging printfs on or off on the fly.

7535619977 Implement the phy-mode property for ate and macb. If it is set to
"rmii", use rmii mode for the MAC, otherwise use MII mode. The code is
somewhat duplicated between these drivers for this.

Also, add AT91RM9200 compatibility strings to the ate driver. In the
future, there's a good chance that ate will lose the MACB support and
only attach to the AT91RM9200 EMAC device since the macb works now
that RMII support has been added to it.

56ea9c7b08 Add support for RMII in macb, cribbed slightly from the ate
driver. This is taken from the MAC at boot, but can be overridden with
'options AT91_MACB_USE_RMII'.

Switch to macb for HL201 and SAM9G20EK boards. It now works both
places. Also start to sneak up on FDT for the SAM9G20EK board, but
leave disabled due to issues with MMC that haven't been resolved.
Add early debug support for the SAM9G20EK since that is required
for FDT to work presently on these SoC.

edc8222303 Make kstack_pages a tunable on arm, x86, and powepc. On i386, the
initial thread stack is not adjusted by the tunable, the stack is
allocated too early to get access to the kernel environment. See
TD0_KSTACK_PAGES for the thread0 stack sizing on i386.

The tunable was tested on x86 only.  From the visual inspection, it
seems that it might work on arm and powerpc.  The arm
USPACE_SVC_STACK_TOP and powerpc USPACE macros seems to be already
incorrect for the threads with non-default kstack size.  I only
changed the macros to use variable instead of constant, since I cannot
test.

On arm64, mips and sparc64, some static data structures are sized by
KSTACK_PAGES, so the tunable is disabled.

721555e7ee Fix KSTACK_PAGES issue when the default value was changed in KERNCONF
If KSTACK_PAGES was changed to anything alse than the default,
the value from param.h was taken instead in some places and
the value from KENRCONF in some others. This resulted in
inconsistency which caused corruption in SMP envorinment.

Ensure all places where KSTACK_PAGES are used the opt_kstack_pages.h
is included.

The file opt_kstack_pages.h could not be included in param.h
because was breaking the toolchain compilation.

4098ccafa4 Revise the arm bus_space implementation to avoid dereferencing the tag on
every operation to retrieve the bs_cookie value almost nothing actually uses.

The bus_space struct contains a private data pointer (poorly named bs_cookie,
now renamed to bs_privdata) which is used only by a few old armv4 xscale
implementations.  The bus_space functions were all defined to take this
value as the first parameter instead of the bus_space_tag_t, requiring all
the inline macro and function expansions to dereference the tag to pass it
to another function, which never uses it.  Now all the functions take the tag
as the first parameter and retrieve the privdata if they need it.

Also fix a couple bus_space_unmap() implementations that were calling
kva_free() instead of pmap_unmapdev().

Multipass attachment is necessary when using vendor-supplied FDT data,

are described in the FDT data.
