02547c5886 lib: Throw an error when ramdisk is present but initrd.size is 0
It fails if you call extract() when ramdisk is present but initrd
size is 0. This CL adds if-statement to throw an error when initrd
size is 0.

90cf4bb02a Revert "src/security/vboot: Add option to skip display init with vboot 2.0"
This reverts commit 598af2e2c2.

Reason for revert: This commit breaks every board with VBOOT enabled
if the platform is apollolake, broadwell, skylake, baswell, baytrails
or icelake. The reason is, that the SoC selects
VBOOT_MUST_REQUEST_DISPLAY by default, and this has a dependency now
on VBOOT_MAY_SKIP_DISPLAY_INIT. This will only be auto-selected if
it is a CHROMEOS platform.

db7a3ae863 src/device/oprom: Fix bootsplash display code for optionroms
So far the bootsplash is only correctly rendered if the framebuffer is
set up as 1024x768@16.
Different resolutions did not show anything, differnent depth resulted
in the distorted images.

This commit removes this limit by using the actual framebuffer resolutions
and combines the code for x86 and yabel.

For the moment the bootsplash is still limited to VGA-OptionROM
framebuffer init.

It was tested in 1280x1024@32 on the wip razer blade stealth using the
intel vgabios.

4c33a3aaa3 src: Make implicit fall throughs explicit
Implicit fall throughs are a perpetual source of bugs and Coverity Scan
issues, so let's squash them once and for all. GCC can flag implicit fall
throughs using the -Wimplicit-fallthrough warning, and this should
ensure no more enter the code base. However, many fall throughs are
intentional, and we can use the following comment style to have GCC
suppress the warning.

    switch (x) {
    case 1:
            y += 1;
	    /* fall through */
    case 2:
            y += 2;
	    /* fall through - but this time with an explanation */
    default:
            y += 3;
    }

This patch adds comments for all remaining intentional fall throughs,
and tweaks some existing fall through comments to fit the syntax that
GCC expects.

80f3ac63f2 fit: Check all compat strings for highest match
The compat string matching code was mostly copied from depthcharge. One
of the few differences is that we now store the list of compat strings
we're willing to match in a list rather than an array. Since our lists
insert at the front, that means the strings are now ordered lowest to
highest (not highest to lowest like in depthcharge).

We did rewrite the compat_rank matching code to accomodate for that...
however, what we didn't do is remove the break-statement in the loop
that matches all compat strings. When we search the lowest priority
first, we can't abort the search as soon as we found a match -- we have
to keep looking because we might find a higher priority match later.

This patch fixes the issue so that my Kevin can actually match for
google,kevin-rev5 (and doesn't just jump at the first best google,kevin
match).

fec4206299 fit: Add device tree compression
This patch adds support for compressing individual device trees in the
FIT image. In order to make this efficient, we'll have to pull the
compatible property out of the FDT and store it directly in the config
node of the FIT image, so that we don't have to scan (and therefore
decompress) every single FDT on boot. Device tree compression is only
supported for FIT images that have this external compatible property.
For older images with no compression, we still support fallback to
scanning the FDT for the property.

b379f1964e fit: Refactor config node handling
This patch makes some minor refactoring to the way the FIT parser
handles config nodes. A lot of this code was written in the dawn age of
depthcharge when its device tree library wasn't as well-stocked yet, so
some of it can be rewritten nicer with more high-level primitives.
There's no point in storing both the string name and the actual FDT node
of a FIT image node separately, since the latter also contains the
former, so remove that. Also eliminate code for the case of not having
an FDT (which makes no sense), and move some more FDT validity/compat
checking into fit_update_compat() (mostly in anticipation of later
changes).

This patch was adapted from depthcharge's http://crosreview.com/1553456
with a couple of modifications specific to coreboot's custom FIT loading
code.

0e9116f0a1 device_tree: Make FDT property data non-const
FDT property data should not be const -- sometimes we need to update it,
for example when fixing up phandles in an overlay. On the other hand
it's occasionally desirable to put a string constant in there without
having to strdup() it all the time... let's just live with the tiny
implicit assumption that the data we'd want to modify (phandle
references, mostly) will never be added from string constants, and put a
cast in dt_add_string_prop().

0d74653bd4 device_tree: Match debug output format to dtc -O dts output
This patch updates the device tree dumping functions (not compiled by
default but available for debugging) to output properties and nodes in a
format similar to .dts files that is very close to what dtc outputs when
you decompile a .dtb with it. This makes it easier to match device tree
dumps from coreboot with device tree dumps generated by other device
tree tooling.

fbec63d15f device_tree: Have absolute paths start with '/'
Currently DT paths are *not* expected to start with '/'. This is not
what the spec says (see Devicetree Specification v0.2, 2.2.3 Path Names)
and also not what is done by Linux.

Change dt_find_node_by_path() to expect paths to start with '/' and add
a leading '/' to all DT path strings. Besides the compatibility with the
spec this change is also needed to support aliases in the future.

f36d53c653 device_tree: Drop sub-node path lookup from dt_find_node_by_path()
Besides looking up a node with an absolute path dt_find_node_by_path()
currently also supports finding a sub-node of a non-root node. All
callers of the function pass the root node though, so it seems there
is no real need for this functionality. Also it is planned to support
DT path names with aliases, which would become messy in combination with
the lookup from a sub-node.

Change the interface of dt_find_node_by_path() to receive the DT tree
object instead of a parent node and adapt all callers accordingly.

6702b68a79 device_tree: Add phandle caching and lookups
This patch caches phandles when unflattening the device tree, so we
don't have to look up the phandle property again every time we're trying
to find the phandle of a node. This is especially important when
supporting phandle lookups, which are also added. In addition we keep
track of the highest phandle in the whole tree, which will be important
for applying overlays later.

With this, dt_get_phandle(node) becomes obsolete because the phandle is
already available as a member variable in the node.

9636a106d4 device_tree: Switch allocations to xzalloc()
The FIT code is already using xzalloc() everywhere, and that's the only
real consumer of device tree code right now. Chances are if you're
trying to unflatten an FDT and it doesn't fit into the heap you're
pretty much screwed anyway, so all the OOM handling feels a bit
unnecessary (and some functions will just silently fail because they
don't have a return value, which is bad). Let's just switch this all to
die on failed allocations.

a66c9b8bf4 string.h: Move common string functions into .c file
There's no clear reason why most of coreboot's basic string functions
are static inline. These functions don't particularly benefit from
inlining (at least not notably more than other functions). This patch
moves them to string.c to be more consistent with our usual coding
practices.

Leaving the ctype functions as static inline because they actually seem
small and collapsible enough that inlining seems reasonable.

Also clarified the situation of strdup() and strconcat() a bit more,
optimized strrchr() to be single-pass, fixed a bug with using strchr()
to find '\0' and got rid of unnecessary register keywords.
