Seems that the 'if (cursor_enabled)' check in
video_console_fixup_cursor() that was removed in chromium.org 1f880bca0 really
meant to check for 'if (console)'. Looks like the whole video console
driver is built extra robust to not fail no matter how screwed up the
console is, so let's add this missing check here as well. Also fixed up
a few other missing 'if (!console)' checks while I'm at it.
However, what payloads should really be doing is check the return value
of video_(console_)init() and not call the other video functions if that
failed. This also adapts video_console_init() to correctly pass through
the return value for that purpose (something that seems to have been
overlooked in the dd9e4e58 refactoring).

The video console runs a video_console_fixup_cursor() function after
every printed character to make sure the cursor is still in the output
window and avoid overflows. For some crazy reason, this function does
not run when cursor_enabled is false... however, that variable is only
about cursor *visibility*, and it's imperative that we still do proper
bounds checking for our output even if the cursor itself doesn't get
displayed (otherwise we can end up overwriting malloc cookies that cause
a panic on the next free() and other fun things like that).
In fact, there seems to be no reason at all to even keep track of the
cursor visibility state in the generic video console framework (the
specific backends already do it, too), so let's remove that code
entirely. Also set the default cursor visibilty in the corebootfb
backend to 0 since that's consistent with what the other backends do.
BUG=None

I always thought the support for multiple logical SCSI units in the USB
mass storage class was a dead feature. Turns out that it's actually used
by SD card readers that provide multiple slots (e.g. one regular sized
and one micro-SD). Implementing perfect support for that would require a
major redesign of the whole MSC stack, since the one device -> one disk
assumption is deeply embedded in our data structures.
Instead, this patch implements a poor man's LUN support that will just
cycle through all available LUNs (in multiple calls to usb_msc_poll())
until it finds a connected device. This should be reasonable enough to
allow these card readers to be usable while only requiring superficial
changes.
Also removes the unused 'protocol' attribute of usb_msc_inst_t.

So I was debugging this faulty USB SD card reader that would just fail
it's REQUEST SENSE response for some reason (sending the CSW immediately
without the data), cursing those damn device vendors for building
non-compliant crap like I always do... when I noticed that we do not
actually set the Allocation Length field in our REQUEST SENSE command
block at all! We set a length in the CBW, but the SCSI command still has
its own length field and the SCSI spec specifically says that the device
has to return the exact amount of bytes listed there (even if it's 0). I
don't know what's more suprising: that we had such a blatant bug in this
stack for so long, or that this card reader is really the first device
to actually be spec compliant in that regard.
This patch fixes the bug and changes the command block structures to be
a little easier to read (why that field was called 'lun' before is
beyond me... LUN is a transport level thing and should never appear in
the command block at all, for any command). It also fixes a memcpy() in
wrap_cbw() to avoid a read buffer overflow that might expose stack frame
data to the device.

clear seemed to work, as the PMIC writes continued (where
they'd hang the system before bus clear) for a couple of regs,
then it hangs hard, no messages, no 2nd lost arb, etc. So
I've added code to the PMIC write function that will reset the

We recently changed the USB stack to detach devices aggressively that we
don't intend to use. This alone is not really a problem, but it
exarcerbates the fact that our device detachment itself is not very
good. We destroy any local info about the device, but we don't properly
disable the offending port. The device keeps thinking that it's active,
and if we later try to reuse that device address for another device
things become confused.
The real fix would be to properly disable all ports that we don't intend
to use. Unfortunately, this isn't really possible in our current
device/hub polymorphism structure, and I don't want to hack a new
disable_port() callback into usbdev_t that really doesn't belong there.
We will only be able to fix this cleanly after we ported all root hubs
to the generic_hub interface.
Until then, an easy workaround is to just avoid reusing addresses as
long as possible. This is firmware, so the chance that we'll ever run
through 127 devices is really small in practice. Even if we ever fix the
underlying issue, it's probably a smart precaution to keep.

TEST=Boot from a hub that has an "unknown" device in an earlier port
than the stick you want to boot from, make sure you can still boot.

The console output driver framework in libpayload is currently built on
the putchar primitive, meaning that every driver's function gets called
one character at a time. This becomes an issue when we add drivers that
could output multiple characters at a time, but have a high constant
overhead per invocation (such as the planned GDB stub, which needs to
wrap a special frame around output strings and wait for an
acknowledgement from the server).
This patch adds a new 'write' function pointer to the
console_output_driver structure as an alternative to 'putchar'. Output
drivers need to provide at least one of the two ('write' is preferred if
available). The CBMEM console driver is ported as a proof of concept
(since it's our most performace-critical driver and should in theory
benefit the most from less function pointer invocations, although it's
probably still negligible compared to the big sprawling mess that is
printf()).
Even with this fix, the problem remains that printf() was written with
the putchar primitive in mind. Even though normal text already contains
an optimization to allow multiple characters at a time, almost all
formatting directives cause their output (including things like
padding whitespace) to be putchar()ed one character at a time.
Therefore, this patch reworks parts of the output code (especially
number printing) to all but remove that inefficiency (directives still
invoke an extra write() call, but at least not one per character). Since
I'm touching printf() core code anyway, I also tried to salvage what I
could from that weird, broken "return negative on error" code path (not
that any of our current output drivers can trigger it anyway).
A final consequence of this patch is that the responsibility to prepend
line feeds with carriage returns is moved into the output driver
implementations. Doing this only makes sense for drivers with explicit
cursor position control (i.e. serial or video), and things like the
CBMEM console that appears like a normal file to the system really have
no business containing carriage returns (we don't want people to
accidentally associate us with Windows, now, do we?).
BUG=chrome-os-partner:18390
TEST=Made sure video and CBMEM console still look good, tried printf()
with as many weird edge-case strings as I could find and compared serial
output as well as sprintf() return value.

Use 'd' instead of 'hhd' when printing absolute year of manufacture. This
is the correct type in this case, as the result is autoatically promoted
to int.
