. interrupt storm detected on "intr70:"; throttling interrupt source;
. Added access serialization on iicbus_transfer(), previously there was
no such protection and a new transfer could easily confuse the
controller;
. Add error checkings (i.e. stop the transfer when a error is detected
and do _not_ overwrite the previous error);
. On command done interrupt do not assume that the transfer was finished
sucessfully as we will receive the command done interrupt even after
errors;
. Simplify the FIFO handling;
. Reset the FIFO between the transfers as the FIFO may contain data from
the last (failed) transfer;

the I2C noise filter (set to one internal clock cycle);

Fix a few issues with creating VOLUME_LABEL for the

- TYPE, BRANCH, and REVISION are only defined if
OSRELEASE is not defined, so in situations where
one might set OSRELEASE for an in-house ISO build,
VOLUME_LABEL would be empty.
- makefs(8) limits the volume label to 32 characters,
which for the powerpc64 case, OSRELEASE expands to
FreeBSD-11.0-CURRENT-powerpc-powerpc64. Even with
removing the prefixing 'FreeBSD-', the string is 30
characters long, leaving zero room for suffixing the
type of ISO media (BO for bootonly, CD for cdrom, and
DVD for dvdrom).
Resolve these by defining VOLUME_LABEL when defining
OSRELEASE if unset. If OSRELEASE is defined by the
builder, use the OSRELEASE from that definition as the
VOLUME_LABEL.
In addition, for cases where both TARGET and TARGET_ARCH
are used for the VOLUME_LABEL, use TARGET_ARCH if it
differs from TARGET.
There are probably a few sharp edges here yet, but these
problems are going to affect the powerpc/powerpc64 builds
