CWARNFLAGS must be added to after including kern.mk, otherwise all the
warnings set in kern.mk are ignored. This is why the
-Wmissing-prototypes warnings were not seen previously.
While here, drop -Wno-pointer-sign as it is doesn't seem to be needed,
but add -Wno-cast-qual to silence warnings for various casts of const
pointers to non-const pointers.

This header duplicates a few #defines in "adf_cfg_strings.h". The
latter header does not use the unneeded parentheses, but if a C file
includes both of these headers, clang raises an error because the macro
is redefined with a different value.

This makes it more obvious that the media being booted is an installer

It also provides a more user-friendly, and more accurate, prompt.

This allows the "Multi user" in "[B]oot Multi user" to be substituted
with another string, for example with "Installer" in installer media.
Note that this is lua-only at the moment, since loader.4th's menu.rc
defines the alternate name as Boot [M]ulti User, unlike lualoader which
leaves it as [B]oot Multi user. Ideally loader.4th would adopt the newer
and simpler lualoader behaviour and then it could gain support for this
option, but loader.4th is on the way out and isn't used by any official
installer media so this is not a significant concern.

Since the revision is stored in two separate byte fields,
the smbios_setenv helper can't be used.

Use a taskqueue instead of a callout.
Callout functions mustn't sleep, where as the TPM driver

The EPSON RX-8035SA I2C RTC has a similar time register layout to the

and control registers. Further generalize ds1307 to make it easier
to add more compatible chips and add support for the EPSON RX-8035SA.

It is desirable to run kboot as the first program in some LinuxBoot
environments. This is the traditional "pid 1" or "init" program. When
running as pid 1. rovide a minimal environment based on what sysvinit,
u-root, initramfs-tools and other like projects do. We mount /dev, /sys,
/proc, make symlinks from /dev/fd to /dev/proc, and create /tmp, /run,
and /var. We also setup stdin/out/err to the console, set the tty
characteristics of same and block the appropriate signals.
This is indended as an environment that never does a fork/exec. If
that's required, the process groups, session leaders and all things
POSIX terminal handlers will need to be added.
Unlike the general purpose linux projects in this area, no attempt is
made to support very old kernels.
When not pid 1, we skip all of the above.

Failure to map RSDP, XSLT and checksum failures are events that can't

Introduce a local change. It seems ieee80211_get_tid() does not deal
with non-dataqos packets unlike net80211's ieee80211_gettid().
Gernally all calls in Linux drivers to ieee80211_get_tid() seem to
be proceeded by an ieee80211_is_data_qos() check.
Moving the ieee80211_get_tid() has no difference in the result, but
(a) saves us the call if we do not need it due to an earlier return,
and (b) allows us to put an assert into the LinuxKPI ieee80211_get_tid()
implementation to avoid accidentally returning random frame header data
in case of a missing earlier ieee80211_is_data_qos() check in (future/
other) drivers.
