re-signed
resign_firmwarefd.sh needs a verifiable copy of the firmware (and associated root key)
to determine the preamble flag value to use.
BUG=chrome-os-partner:6874
TEST=manually tested resigning a firmware .bin using sign_firmware.sh. Verified correct
preamble flag determination.

This adds a flag to the list of values returned by VbInit(). When
this flag is set, the BIOS may be asked to boot something other than
ChromeOS. If this requires some sort of special preparation, the BIOS
should do it.
BUG=chromium-os:22454
TEST=none
There is no test for this. It requires a change to the BIOS in order
to do anything differently, and we haven't yet decided whether the
BIOS should pay attention to it.

A legacy checksum in CMOS is not maintained by coreboot and may be invalid. If
the Linux kernel driver sees that the checksum is wrong, it will return EIO
when read from or written to. That makes crossystem return an error since it
can't read the CMOS, and it also prevents it from changing some settings.
One way to fix the problem would be to remove the checksum check in the kernel
driver. This would change the semantics of the driver so that either x86 was
inconsistent with the other architectures, or change the semantics of those
other architectures as well.
Another option would be to fix the checksum during manufacturing since nothing
should be changing those particular bytes of CMOS. The problem with this
approach is that something might corrupt the CMOS after manufacturing, and
we'd have the same problem again.
Yet another solution would be to make the firmware, most likely coreboot,
actually keep the checksum up to date. This seems like an awful waste of boot
time, the bytes protected by the checksum aren't actually used by anything,
and the bytes of the CMOS that are used are protected by vboot using its own
checksum.
The solution implemented here is to make crossystem recognize when the driver
has determined that the checksum is invalid and make it call an ioctl that
gets the driver to fix the checksum. Wrapper functions for fread, fwrite,
fgetc, and fputc are implemented which first attempt to read or write, on
failure check for the EIO error code, and if they find it to call the
appropriate ioctl and attempt the access again. This way, we won't take any
extra time to talk to the CMOS when everything is working properly, and when
there's a problem it gets fixed up transparently. One problem with this
approach is that using the /dev/nvram device file will still fail until
crossystem is run at least once and given a chance to fix the checksum.
BUG=chrome-os-partner:6718
TEST=For version 1, verified that crossystem reported an error on Sameer's
Lumpy. Used strace to verify that crossystem received an EIO error when trying
to read or write /dev/nvram. Built a new image with this change and booted it
using a USB stick. Ran crossystem and verified that crossystem no longer
reported an error. Rebooted into the original image and verified that
crossystem worked there as well, indicating that the persistent problem in the
CMOS had been corrected.
For version 2, the same as version 1 except that I used a custom version of
u-boot to purposefully corrupt the CMOS rather than using Sameer's Lumpy.

As shipped, H2C only loads the option ROM for the built-in video, and that
only when it needs display the BIOS warning screens.
By setting a flag in the GBB, you can allow all option ROMs to be loaded:
Note that we'll never enable this ourselves (and there's a factory test to
ensure that*) because it executes non-verified code. But if a customer wants
to void their warranty and set this flag in the read-only flash so they can
install and use other PCI devices, they should be able to do so.
BUG=chrome-os-partner:6148
TEST=none
The only way to test this is to use a BIOS that was compiled with serial
debugging enabled, so there's nothing for QA to do. If you have such a BIOS,
you can see the difference like so:
flashrom -r oldbios.bin
gbb_utility -s --flags=2 oldbios.bin newbios.bin
flashrom -w newbios.bin
<reboot>
When bit 1 of the GBB flags is 0, you'll see these lines in the serial
output:
LoadOpRomImage-->GetSystemConfigurationTable Status = Success
LoadOpRomImage-->GetH2cBootMode Status = Success
When bit 1 of the GBB flags is 1, you'll see these lines in the serial
output:
LoadOpRomImage-->GetSystemConfigurationTable Status = Success
LoadOpRomImage-->GetH2cBootMode Status = Success
LoadOpRomImage-->PCI OpRom on 1.0.0 is allowed!!!
This happens in any boot mode (normal, developer, recovery).

*The factory test for GBB zero flags is gft_clear_gbb_flags.sh, in
src/platform/factory_test_tools

Although we're now using a single unified BIOS, it is pretty nice to be able
to get a shell in developer mode while still using verified boot for the
kernel and filesystem. Alex & ZGB implemented this by requiring the dev-mode
user to install a special dev-mode BIOS. We don't do that, but we DO require
setting a special flag with "crossystem" to accomplish the same thing.
In order to allow booting a self-signed kernel, you must boot in developer
mode, open a shell, and run this:
crossystem dev_boot_custom=1
Special note to internal developers: If you're in the habit (as I am) of
booting directly from a USB stick in dev-mode, you'll have to run this:
crossystem dev_boot_custom=1 dev_boot_usb=1
Just using dev_boot_usb=1 is no longer enough, because the USB kernel is
signed using the recovery key and by pressing Ctrl-U, we validate it with
the kernel data key. That worked before this change because any self-signed
kernel was fine, and that's how the USB key was treated. Now it actually
requires a verified signature until you enable dev_boot_custom=1 also.
BUG=chrome-os-partner:5954
TEST=manual
Boot once in normal mode, which clears the special flags. Then switch to
developer mode. You should be able to boot and get a root shell.
Run
crossystem dev_boot_usb=1
Obtain a USB recovery image that's keyed differently. For example, if you're
testing with dev-keys, use a PVT-signed image or vice-versa.
Reboot into dev-mode with the USB recovery stick inserted. At the dev-mode
screen, press Ctrl-U. You should hear a single beep, but it should not boot.
Press Ctrl-D to boot from the hard drive, log in to a shell and run
crossystem dev_boot_custom=1
Repeat the previous test. This time when you press Ctrl-U, it should boot
the recovery image. Turn the system off before it does anything.
That's it.

We should have been using Droid Sans, not Helvetica, and some of the
non-Roman locales need special handling to render clearly and correctly. We
also get better results if we avoid scaling after rendering the text.
Added scripts/newbitmaps/Makefile to regenerate it all, updated the READMEs.
Since Hung-Te figured out how to use pango-view to render the UTF-8
reliably, we don't need to keep all the pre-rendered locale images anymore
either.
This provides the x86 bmpblock for Stumpy PVT. We may need some more
tweaking for Lumpy and/or ARM.

- This change also drops the -march=i386 and thus allows

User our new officially finally final localizations for Stumpy.
Start by removing some of the subtle speckles from the background images so
they'll compress a little better, then modify the Makefile to autogenerate
the bitmap blob (for x86, anyway).
Note: the size improvment isn't much, but every little bit helps. With all
43 locales, bmpblock.bin was 659798 bytes. Now it's 665142 (5344 bytes saved).
And, no, we can't fit all 43 locales in our current BIOS. Yet.

The -isystem and the rest of the CFLAGS for firmware builds is copied
from U-Boot, where U-Boot generates it on the fly, as a temporary
solution before we figure out how make the CFLAGS right.
Given that, the hard-coded -isystem is both incorrect (since tool chain
is upgraded to a new version) and unnecessary. It is unnecessary
because firmware lib is carefully written that the lib does not (and
probably should not) depend on any system header.
Even if in the future a system header is added to the firmware lib,
because firmware build sets -nostdinc to CFLAGS, the compiler will
safely report missing header instead of silently using the standard
system header.
So this commit removes the -isystem.

In the unlikely case that params is not set or the LoadKernelParams
structure is not initialized correctly, LoadKernel will exit before
initializing shcall. However, in LoadKernelExit it will be used to
stire the function's return code, thus potentially dereferencing a
NULL pointer.

* Updated the text strings using the latest results from the localization
experts.
* Strip the leading byte-order-mark and trailing whitespace from the text
files, since it's not used for anything and sometimes renders as a box.
* Added options to the text_to_bmp script to handle right-to-left languages
and to override the font.
* Added scripts/newbitmaps/strings/localized_text/Makefile to regenerate all
the bitmaps from the text strings. This handles right-to-left languages
correctly.
* Modified make_default_yaml so that the th/model.txt string is moved up a
bit to align it properly with the HWID.
* Regenerated DEFAULT.yaml using the new bitmaps.

This displays the gbb.flags value when being warned about it being nonzero.
It also decodes the recovery_reason value into English.
BUG=chromium-os:20972
TEST=manual
1. Use gbb_utility to create a BIOS with valid bitmaps, but with gbb.flags
set to a non-zero value. Boot into recovery mode. You should see the
warning that gbb.flags is non-zero, and the value itself.
2. Press TAB. The recovery_reason field should display not only a value, but
also an English string explaining the value.

This enables us to support playing sounds in the background if the BIOS
allows it, so we don't have to block while beeping is happening. The new
declaration is:
VbError_t VbExBeep(uint32_t msec, uint32_t frequency);
If the audio codec can run in the background, then:
zero frequency means OFF, non-zero frequency means ON
zero msec means return immediately, non-zero msec means delay (and
then OFF if needed)
else:
non-zero msec and non-zero frequency means ON, delay, OFF, return
zero msec or zero frequency means do nothing and return immediately
The return value is used by the caller to determine the capabilities. The
implementation should always do the best it can if it cannot fully support
all features - for example, beeping at a fixed frequency if frequency
support is not available. At a minimum, it must delay for the specified
non-zero duration.
Currently, VbExBeep() is called only when displaying the dev-mode screen.
BUG=none
TEST=manual
I've tested on x86 and ARM, all timeouts and noises work as before.
Note that ARM and coreboot will require a corresponding change to their
VbExBeep() implementations, which will have to be handled with separate,
simultaneous CLs.

Work around the fact that we have 3 different verity kernel arguments depending
on the image being signed (legacy parameters, new key=value parameters, new key=
value parameters with salt).
Since the signer is not branch conscious, expect and use the old verity binary to
be present when legacy kernel arguments are specified. The last 2 types of verity
arguments can be distinguished based on whether a salt is present.
BUG=chromium-os:20640
TEST=manually tested by signing r14, r15 and r16 images and verifying

This is again working around the fact that the signer isn't branch

verity parameter styles in use.
