Sol Boucher 023e829423 fmaptool: Add listing of annotated CBFS sections and generate header
The fmd compiler now processes "(CBFS)" annotations, distilling them
into a comma-separated list of the names of sections containing
CBFSes. This list is the only thing printed to standard output to
enable easy capture and machine consumption by other tools.
Additionally, the ability to generate a tiny header with a define for
the primary CBFS's size is implemented and can be requested via a
new command-line switch.

Here's an example of how to use the new features:
 $ ./fmaptool -h layout.h layout_arm_8192.fmd layout.fmap 2>/dev/null
 FW_MAIN_A,FW_MAIN_B,COREBOOT
The hypothetical fmd file contains three sections annotated as (CBFS),
the names of which are printed to standard output. As before, a binary
FMAP file named layout.fmap is created; however, because the command
was invoked with -h, a header #define ing the offset of its FMAP
section (i.e. where it will be relative to the base of flash once the
boot image is assembled) is also generated.

BUG=chromium:470407
TEST=Verify that fmd files without a "COREBOOT" section or with one
that isn't annotated as "(CBFS)" are not accepted. Ensure that the
list of CBFS sections matches the descriptor file's annotations and
is led by the "COREBOOT" section. Invoke with the header generation
switch and check that output file for reasonableness.

Sol Boucher e3260a042f cbfstool: Restructure around support for reading/writing portions of files
The buffer API that cbfstool uses to read and write files only directly supports
one-shot operations on whole files. This adds an intermediate partitioned_file
module that sits on top of the buffer system and has an awareness of FMAP
entries. It provides an easy way to get a buffer for an individual region of a
larger image file based on FMAP section name, as well as incrementally write
those smaller buffers back to the backing file at the appropriate offset. The
module has two distinct modes of operation:
- For new images whose layout is described exclusively by an FMAP section, all
the aforementioned functionality will be available.
- For images in the current format, where the CBFS master header serves as the
root of knowledge of the image's size and layout, the module falls back to a
legacy operation mode, where it only allows manipulation of the entire image
as one unit, but exposes this support through the same interface by mapping
the region named SECTION_NAME_PRIMARY_CBFS ("COREBOOT") to the whole file.

The tool is presently only ported onto the new module running in legacy mode:
higher-level support for true "partitioned" images will be forthcoming. However,
as part of this change, the crusty cbfs_image_from_file() and
cbfs_image_write_file() abstractions are removed and replaced with a single
cbfs_image function, cbfs_image_from_buffer(), as well as centralized image
reading/writing directly in cbfstool's main() function. This reduces the
boilerplate required to implement each new action, makes the create action much
more similar to the others, and will make implementing additional actions and
adding in support for the new format much easier.

Sol Boucher 1a3349ffd1 cbfstool: Simplify the common buffer_splice() function's interface
Previously, this function allowed one to pass a size of 0 in order to
indicate that the entire buffer should be copied. However, the
semantics of calling it this way were non-obvious: The desired
behavior was clear when the offset was also 0, but what was the
expected outcome when the offset was nonzero, since carrying over the
original size in this case would be an error? In fact, it turns out
that it always ignored the provided offset when the size was zero.
This commit eliminates all special handling of 0; thus, the resulting
buffer is exactly as large as requested, even if it's degenerate.
Since the only consumer that actually called the function with a size
of 0 was buffer_clone(), no other files required changes.

This patches a memory leak on every struct cbfs_image creation that

commit, the CBFS master header has been copied to a separate buffer so
that its endianness could be fixed all at once; unfortunately, this
buffer was malloc()'d but never free()'d. To address the issue, we
replace the structure's struct cbfs_header * with a struct cbfs_header
to eliminate the additional allocation.

To test this ran the following script

echo > /tmp/build.log

  build_dirs="${build_root}build/peppy"
  if [ -n "${build_root}" ]; then
    build_dirs+=" $(realpath ${build_root})/build/peppy"

    echo "building in ${build_dir}" >> /tmp/build.log
    if ! make obj=${build_dir}; then
      exit

  done
done

and then checked the generated file:

Sol Boucher 636cc858bb cbfstool: Make the add action choose an aligned entries capacity
This fixes an inconsistency between `cbfstool create` and `cbfstool add` that
was resulting in confusing claims about the amount of free space at the end of a
CBFS. Calls to `cbfstool add` check whether a file fits under a given empty file
entry by testing whether it would collide with the beginning of the *subsequent*
file header; thus, if a file's end is unaligned, its reported size will not
match the actual available capacity. Although deleted entries always end on an
alignment boundary because `cbfstool remove` expands them to fill the available
space, `cbfstool create` doesn't necessarily size a new entries region to result
in an empty entry with an aligned end.
This problem never resulted in clobbering important data because cbfstool would
blindly reserve 64B (or the selected alignment) of free space immediately after
the all-inclusive empty file entry. This change alters the way this reservation
is reported: only the overhang past the alignment is used as hidden padding, and
the empty entry's capacity is always reported such that it ends at an aligned
address.
Much of the time that went into this patch was spent building trust in the
trickery cbfstool employs to avoid explicitly tracking the image's total
capacity for entries, so below are two proofs of correctness to save others time
and discourage inadvertent breakage:

OBSERVATION (A): A check in cbfs_image_create() guarantees that an aligned CBFS
empty file header is small enough that it won't cross another aligned address.

OBSERVATION (B): In cbfs_image_create(), the initial empty entry is sized such
that its contents end on an aligned address.

THM. 1: Placing a new file within an empty entry located below an existing file
entry will never leave an aligned flash address containing neither the beginning
of a file header nor part of a file.
 We can prove this by contradiction: assume a newly-added file neither fills to
 the end of the preexisting empty entry nor leaves room for another aligned
 empty header after it. Then the first aligned address after the end of the
 newly-inserted file...
  - CASE 1: ...already contains a preexisting file entry header.
    + Then that address contains a file header.
  - CASE 2: ...does not already house a file entry header.
    + Then because CBFS content doesn't fall outside headers, the area between
      there and the *next* aligned address after that is unused.
    + By (A), we can fit a file header without clobbering anything.
    + Then that address now contains a file header.

THM. 2: Placing a new file in an empty entry at the very end of the image such
that it fits, but leaves no room for a final header, is guaranteed not to change
the total amount of space for entries, even if that new file is later removed
from the CBFS.
 Again, we use contradiction: assume that creating such a file causes a
 permanent...
  - CASE 1: ...increase in the amount of available space.
    + Then the combination of the inserted file, its header, and any padding
      must have exceeded the empty entry in size enough for it to cross at
      least one additional aligned address, since aligned addresses are how
      the limit on an entry's capacity is determined.
    + But adding the file couldn't have caused us to write past any further
      aligned addresses because they are the boundary's used when verifying
      that sufficient capacity exists; furthermore, by (B), no entry can ever
      terminate beyond where the initial empty entry did when the CBFS was
      first created.
    + Then the creation of the file did not result in a space increase.
  - CASE 2: ...decrease in the amount of available space.
    + Then the end of the new file entry crosses at least one fewer aligned
      address than did the empty file entry.
    + Then by (A), there is room to place a new file entry that describes the
      remaining available space at the first available aligned address.
    + Then there is now a new record showing the same amount of available space.
    + Then the creation of the file did not result in a space decrease.

Aaron Durbin 7aafe5303b timestamp: fix incremental linking error for !HAVE_MONOTONIC_TIMER
In linking ramstage a single object file is created before linking
with the linker script. Though there is a weak timestamp_get() symbol
in timestamp.c any of its dependent symbols need to be available
during the incremental link. As not all platforms have
HAVE_MONOTONIC_TIMER enabled this will create a linking error.
Fix this by providing a hint to the compiler to remove dead code
and thus the dependent symbols causing linking errors in the presence
of !HAVE_MONOTONIC_TIMER.
