Using latest U-Boot for RPI 1 or 2 the DTB loaded by the firmware is discarded.
The DTB was previously patched by the firmware to contain the DMA channel mask.
DTB provided by the rpi firmware or DTS in the Linux tree contain the raw value
directly. Do the same for our DTS as we cannot switch to the upstream ones yet.
Not having the DMA channel mask setup properly cause mmc not to be detected
(and probably other problems on driver using DMA).
Also, add links for rpi dtb to the name used by u-boot. This way the dtb can be
loaded by ubldr using the U-Boot env variable fdtfile.
Tested On: RPI B Rev2, RPI Zero, RPI 2 v1.1 RPI 2 v1.2

and repurposing "blink". Improve accuracy of documentation of historical
mistakes and other bugs.
"blink" now means "set the blink attribute for the target(s)" instead of
"set the blink attribute and clear other attributes [and control flags]".
It was even more confusing to use "blinking" for the single attribute to
keep the old meaning for "blink".
"destructive" is not as historically broken or gone as the previous version
said.
The bugs involving resetting from defaults are now understood and partly
documented (the defaults are mis-initialized).
Previouly it was possible to create users with spaces in the name with:
pw useradd -u 1234 -g 1234 -n 'test user'
The "-g 1234" is relevant, without it the name was already rejected
as expected:
[fk@test ~]$ sudo pw useradd -u 1234 -n 'test user'
pw: invalid character ` ' at position 4 in userid/group name
Bug unintentionally found with a salt config without explicit name entry:
test user:
user.present:
- uid: 1234
- gid: 1234
- fullname: Test user
- shell: /usr/local/bin/bash
- home: /home/test
- groups:
- wheel
- salt
"Luckily" salt modules rarely bother with input validation either ...

"pw usermod someuser -G ''" is supposed make sure that someuser

Previouly it was a nop because split_groups() only intitialised
"groups" if at least one group was specified. As a result the
existing secondary group memberships were kept.

was aliased to a vt sequence, causing and fixing various bugs.
For syscons, this restores support for arg 2 which sets blinking block
too forcefully, and restores bugs for arg 0 and 1. Arg 2 is used for
vs in the cons25 entry in termcap, but I've never noticed an application
that uses this. The bugs involve replacing local settings by global
ones and need better handling of defaults to fix.
For vt, this requires moving the aliasing code from teken to vt where
it belongs. This sequences is very important for cons25 compatibility
in vt since it is used by the cons25 termcap entries for ve, vi and
vs. vt can't properly support vs for either cons25 or xterm since it
doesn't support blinking. For xterm, the termcap entry for vs asks
for something different using 12;25h instead of 25h.
Rename C25CURS for this to C25LCT and change its description to be closer
to echoing the old comment about it. CURS is too generic.
Fix missing syscons escape sequence for setting the global cursor shape
(and type). Only support this in syscons since vt can't emulate anything
in it.
In a recent commit, I forgot to expand an X to an abbreviation of "BORDER".
Fix this and some nearby bad names.
The descriptions were copied from comments in scterm-sc.c, but some
of these are bad. The border [color] was inconsistently described as
a property of the "display", but I had changed this to "adapter" to
match the descriptions for other color settings. All colors supported
by the cons25 sequences are actually properties of the current vty and
that should not be described. But the other colors are defaults.
Change "adapter" to "default" for them and remove "adapter" for the
border. Reduce the verbosity of the abbreviation from AD to D.
It should toggle between 2 states, but it used a cut-down version of
support for a related 3-state syscons escape sequence and inherited
bugs from that. The usual misbehaviour was that hiding and showing
the cursor reset it to a global default.
Support for the 3-state sequence remains broken by aliasing to the 2-state
sequence. This works better but incompatibly for the 2 cases that it
supports.
Make sure that the flags INP_IPV4 and INP_IPV6 are consistently set
for inpcbs used for TCP sockets, no matter if the setting is derived
from the net.inet6.ip6.v6only sysctl or the IPV6_V6ONLY socket option.
For UDP this was already done right.

sbuf is filled to capacity by vsnprintf(), the loop exits without error, and
the sbuf is not marked as auto-extendable.
SBUF_HASROOM() evaluates true if there is room for one or more non-NULL
characters, but in the case that the sbuf was filled exactly to capacity,
SBUF_HASROOM() evaluates false. Consequently, sbuf_vprintf() incorrectly
assigns an ENOMEM error to the sbuf when in fact everything is fine, in turn
poisoning the buffer for all subsequent operations.
Correct by moving the ENOMEM assignment into the loop where it can be made
unambiguously.
As a related safety net change, explicitly check for the zero bytes drained
case in sbuf_drain() and set EDEADLK as the error. This avoids an infinite loop
in sbuf_vprintf() if a drain function were to inadvertently return a value of
zero to sbuf_drain().
