The delta between SENTRY5 and BCM was already small due to BCM being
derived from SENTRY5; re-integrating the two avoids the maintenance
overhead of keeping them both in sync with bhnd(4) changes.
- Re-integrate minor SENTRY5 deltas in bcm_machdep.c
- Modify uart_cpu_chipc to allow specifying UART debug/console flags via
kenv and device hints.
- Switch SENTRY5 to std.broadcom
- Enabled CFI flash support for SENTRY5

Now that bhnd(4) provides feature parity with the previous siba/mips
implementation, we can switch sentry5 over and begin lifting common
support code out for use across bhnd(4) embedded targets.
Changes:
- Fixed enumeration of siba(4) per-core address maps, required for
discovery of memory mapped chipc flash region on siba(4) devices.
- Simplified bhnd kernel configuration (dropped 'bhndbus' option).
- Replaced files.broadcom's direct file references with their
corresponding standard kernel options.
- Lifted out common bcma/siba nexus support, inheriting from the new
generic bhnd_nexus driver.
- Dropped now-unused sentry5 siba code.
- Re-integrated BCM into the universe build now that it actually compiles.

Etherswitch support is built by default on all SoCs except RT3662/RT3883
as they have no built-in switch and their configurations with external
switches are not yet supported.

There files contains machine-dependent code for Broadcom MIPS processor and

This is a work in progress; it and the current bhnd code is enough to boot

legacy siba sentry5 cpu glue.
The siba_cc code is the hard-coded chipcommon bits for the sentry s5,
which will eventually be replaced with the more flexible bhnd sipa/cc
code.
bwn, etc uses siba_bwn, which doesn't use siba or siba_cc to do anything.
Only compile what each SoC needs and get rid of MEDIATEK generic config.

the following:
1. Give the appropriate board dts file to be used by either:
1.1. edit the SoC kernel config required (e.g., MT7620A_FDT) and include
the required FDT_DTS_FILE makeoption; or
1.2. simply supply FDT_DTS_FILE="xx.dts" on the command line when building
the kernel
Of course, the user can also create a completely new kernel config to
match the desired board and include the SoC kernel config from within
it.
If required, edit the MEDIATEK config file, which includes optional
drivers and comment out the unneeded ones.
2.1. this would only make sense if kernel size is a concern. Even if we
build the kernel with all drivers, if we lzma it and package it as a uImage,
its size is still around 1.1MiB.
The user will have to choose a dts file (or create a new one) from
sys/gnu/dts/mips , where all Mediatek/Ralink dts files will be imported via
a later revision.

This revision does the following renames:
CPU_MIPS24KC -> CPU_MIPS24K
CPU_MIPS74KC -> CPU_MIPS74K
CPU_MIPS1004KC -> CPU_MIPS1004K
It also adds the following new CPU_MIPSxxx options:
CPU_MIPS24KE, CPU_MIPS34K, CPU_MIPS1074K, CPU_INTERAPTIV, CPU_PROAPTIV
CPU_MIPSxxxxKC is limiting and possibly misleading as it implies the
MIPSxxxxK CPU has no FPU.
It would be better if the CPUs are named after their standard functionalities
only and the presence or absence of FPU can then be controlled via the
CPU_HAVEFPU option.
I will send out another dependent revision that moves MIPS 32 r2 and r3
CPUs to use the EHB instruction for clearing hazards instead of NOP/SSNOP.

This is an AR9331 part based on the AP121 reference design but with
32MB RAM. Yes, it has 4MB flash and it has no USB, so clever hacks
are required to get it up and working.
But boot/work it does.
The ERL is a fairly cheap (~$100 USD) and readily available dual core
MIPS64 device so it makes a useful MIPS reference platform.
This is based in part on the kernel config generated by the mkerlimage
script from http://rtfm.net/FreeBSD/ERL/.

* Shuffle the kernel to be at the beginning
* Give the kernel 2mb, the rootfs 6mb, and 'mib0' the rest
* put the cfg parition just before the ART calibration data for the
wifi part in the SoC
* .. and make sure ART points to the right 64k region.
I've updated the freebsd-wifi-build wiki the instructions on using this.
If someone has an AP135 with 8MB SPI flash then this won't work; everything
minus the big mib0 partition is just a bit over 8MB. Come see me if this
ever happens (you'll likely just have to shrink the rootfs and the kernel
a little in order to make it fit.)
Tested:
* AP135 reference board.
The SoC, the flash, the ethernet ports and ethernet switch all work.
The USB works.
The 11ac PCIe NIC internally is at least seen by the PCIE RC, but
I haven't tried using it yet. There's no driver and I haven't
yet swapped it out for a non-11ac chip.
The on-chip 2GHz wifi works, but there are some data errors that
get thrown up in STA mode when scanning. I have a feeling I have
to finish the DDR flush code out and have it run correctly on the
shared interrupts; that'll take a bit of time to get right.
But if you're after an updated piece of hardware, the Archer C7 v2
is certainly there, and you can replace the 11ac NIC with a 3x3
Atheros PCIe device (eg AR9380, AR9390, AR9580, etc) and it'll
"just work".
Tested:
* TP-Link archer c7v2.
The Tp-link Archer-C7v2 unit has a QCA9558 internally but hangs the
QCA988x 11ac PCIe NIC off of PCI RC #1, not #0.
So I actually finally /do/ have a board to verify whether PCIe is working.
Grr.
Tested:
* TP-Link Archer-C7v2.

- Update copyright.
- Make kernel options for RANDOM_YARROW and RANDOM_DUMMY. Set
neither to ON, which means we want Fortuna
- If there is no 'device random' in the kernel, there will be NO
random(4) device in the kernel, and the KERN_ARND sysctl will
return nothing. With RANDOM_DUMMY there will be a random(4) that
always blocks.
- Repair kern.arandom (KERN_ARND sysctl). The old version went
through arc4random(9) and was a bit weird.
- Adjust arc4random stirring a bit - the existing code looks a little
suspect.
- Fix the nasty pre- and post-read overloading by providing explictit
functions to do these tasks.
- Redo read_random(9) so as to duplicate random(4)'s read internals.
This makes it a first-class citizen rather than a hack.
- Move stuff out of locked regions when it does not need to be
there.
- Trim RANDOM_DEBUG printfs. Some are excess to requirement, some
behind boot verbose.
- Use SYSINIT to sequence the startup.
- Fix init/deinit sysctl stuff.
- Make relevant sysctls also tunables.
- Add different harvesting "styles" to allow for different requirements
(direct, queue, fast).
- Add harvesting of FFS atime events. This needs to be checked for
weighing down the FS code.
- Add harvesting of slab allocator events. This needs to be checked for
weighing down the allocator code.
- Fix the random(9) manpage.
- Loadable modules are not present for now. These will be re-engineered
when the dust settles.
