Patrick Georgi 7a33b53dc0 cbfstool: Don't patch cbfs_file->len, it's already set correctly
->len used to be set to the file data length plus the size of the
padding used for the cbfs_file header. This isn't the case anymore,
so no patching of this field is necessary anymore.

->offset still needs to be patched in that case because its final
value can only be determined when the file's actual location is known.

Patrick Georgi 62c014bcf3 cbfstool: start moving cbfs_file header creation up the call chain
Up to now cbfstool creates the cbfs_file header at the latest possible
time, which is unsuitable when the idea is to add further fields to it
that need to be configured earlier.

Thus, have it ripple up the call chain.

Patrick Georgi dd2d3f933a cbfstool: unify actual file creation
After the preparation in earlier commits, it is now possible to handle the
more general case of position independent files using the special code path
for fixed location files.

This leads to a single place where non-empty cbfs file headers are actually
written into the image, allowing us to move it up the chain more easily.

So far it's still unused, but its purpose will change:
It will become an offset to another structure that contains additional file

This change is compatible because the binary format doesn't change and so far
the field was always set to 0, which can serve nicely as 'unused' field.

requirements, the logic for the optional read and all writing is
implemented in the cbfs_update_fit() function itself, rather than
relying on the main() function for writing as the other actions do.

Patrick Georgi b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

The cbfstool handling of new-style FMAP-driven "partitioned" images
originally disallowed the use of x86-style top-aligned addresses with
the add.* and layout actions because it wasn't obvious how they should
work, especially since the normal addressing is done relative to each
individual region for these types of images. Not surprisingly,
however, the x86 portions of the build system make copious use of
top-aligned addresses, so this allows their use with new images and
specifies their behavior as being relative to the *image* end---not
the region end---just as it is for legacy images.

Sol Boucher 67a0a864be cbfstool: New image format w/ required FMAP and w/o CBFS master header
These new-style firmware images use the FMAP of the root of knowledge
about their layout, which allows them to have sections containing raw
data whose offset and size can easily be determined at runtime or when
modifying or flashing the image. Furthermore, they can even have
multiple CBFSes, each of which occupies a different FMAP region. It is
assumed that the first entry of each CBFS, including the primary one,
will be located right at the start of its region. This means that the
bootblock needs to be moved into its own FMAP region, but makes the
CBFS master header obsolete because, with the exception of the version
and alignment, all its fields are redundant once its CBFS has an entry
in the FMAP. The version code will be addressed in a future commit
before the new format comes into use, while the alignment will just be
defined to 64 bytes in both cbfstool and coreboot itself, since
there's almost no reason to ever change it in practice. The version
code field and all necessary coreboot changes will come separately.

then try printing its layout and CBFSes' contents, add and remove CBFS

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.

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.

Sol Boucher 057256541b cbfstool: Fix ability to add files at offsets near the end of empty spaces
Because cbfs_add_entry_at() previously *assumed* it would have to create a
trailing empty entry, it was impossible to add files at exact offsets close
enough to the end of an existing empty entry that they occupied the remainder
of its space. This addresses the problem by skipping the step of creating the
trailing empty entry if doing so would place it at the start offset of whatever
already followed the original empty section.

Sol Boucher 0e53931fee cbfstool: Clean up in preparation for adding new files
This enables more warnings on the cbfstool codebase and fixes the
issues that surface as a result. A memory leak that used to occur
when compressing files with lzma is also found and fixed.
Finally, there are several fixes for the Makefile:
 - Its autodependencies used to be broken because the target for
   the .dependencies file was misnamed; this meant that Make
   didn't know how to rebuild the file, and so would silently
   skip the step of updating it before including it.
 - The ability to build to a custom output directory by defining
   the obj variable had bitrotted.
 - The default value of the obj variable was causing implicit
   rules not to apply when specifying a file as a target without
   providing a custom value for obj.
 - Add a distclean target for removing the .dependencies file.

Vadim Bendebury 5e273a4577 cbfstool: add a command to duplicate a cbfs instance
The new command allows to create a file where the original CBFS image
is duplicated at a different offset.

The required options of the new command are -D, the offset where the
copy CBFS header is placed, and -s, the size of the new CBFS copy.

When a CBFS is copied, the bootblock area of the source CBFS is
ignored, as well as empty and deleted files in the source CBFS. The
size of the destination CBFS is calculated as the rombase size of the
source CBFS less the bootblock size.

The copy instance can be created in the image only above the original,
which rules out the use of this new command for x86 images. If
necessary, this limitation could be addressed later.

As with other cbfstool commands, unless explicitly specified the
lowest CBFS instance in the image is considered the source. If
necessary, the user can specify the source CBFS using the -H option.

Vadim Bendebury 458a12e52b cbfstool: allow user to explicitly specify header location
There potentially could be multiple CBFS instances present in the
firmware image. cbfstool should be able to operate on any of them, not
just the first one present.

To accomplish that, allow all CBFS commands to accept the -H parameter
(which specifies the exact CBFS header location in the image).

If this parameter is specified, the image is not searched for the CBFS
header, only the specified location is checked for validity, If the
location is valid, it is considered to be the CBFS header, if not -
the tool exits with an error status.

Note, that default behavior of the tool does not change.

Julius Werner efcee767de CBFS: Automate ROM image layout and remove hardcoded offsets
Non-x86 boards currently need to hardcode the position of their CBFS
master header in a Kconfig. This is very brittle because it is usually
put in between the bootblock and the first CBFS entry, without any
checks to guarantee that it won't overlap either of those. It is not fun
to debug random failures that move and disappear with tiny alignment
changes because someone decided to write "ORBC1112" over some part of
your data section (in a way that is not visible in the symbolized .elf
binaries, only in the final image). This patch seeks to prevent those
issues and reduce the need for manual configuration by making the image
layout a completely automated part of cbfstool.

Since automated placement of the CBFS header means we can no longer
hardcode its position into coreboot, this patch takes the existing x86
solution of placing a pointer to the header at the very end of the
CBFS-managed section of the ROM and generalizes it to all architectures.
This is now even possible with the read-only/read-write split in
ChromeOS, since coreboot knows how large that section is from the
CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be
changed on systems that place other data next to coreboot/CBFS in ROM).

Also adds a feature to cbfstool that makes the -B (bootblock file name)
argument on image creation optional, since we have recently found valid
use cases for CBFS images that are not the first boot medium of the
device (instead opened by an earlier bootloader that can already
interpret CBFS) and therefore don't really need a bootblock.

BUG=None

This adds a few new file types to cbfstool.  Currently these
files are being added using bare hex values in the coreboot

to help get rid of some confusion in the values used within the

All of these new types are roughly equivalent to raw.

Gabe Black 845aa1416d cbfstool: If compression fails, warn and use the uncompressed data.
The LZMA compression algorithm, currently the only one available, will fail
if you ask it to write more data to the output than you've given it space for.
The code that calls into LZMA allocates an output buffer the same size as the
input, so if compression increases the size of the output the call will fail.
The caller(s) were written to assume that the call succeeded and check the
returned length to see if the size would have increased, but that will never
happen with LZMA.

Rather than try to rework the LZMA library to dynamically resize the output
buffer or try to guess what the maximal size the data could expand to is, this
change makes the caller simply print a warning and disable compression if the
call failed for some reason.

This may lead to images that are larger than necessary if compression fails
for some other reason and the user doesn't notice, but since compression
errors were ignored entirely until very recently that will hopefully not be
a problem in practice, and we should be guaranteed to at least produce a
correct image.

Gabe Black dbd006b082 cbfstool: Propogate compression errors back to the caller.
When compression fails for whatever reason, the caller should know about it
rather than blindly assuming it worked correctly. That can prevent half
compressed data from ending up in the image.

This is currently happening for a segment of depthcharge which is triggering
a failure in LZMA. The size of the "compressed" data is never set and is
recorded as zero, and that segment effectively isn't loaded during boot.

the actual use of aarch64 ELF files actually "just works" (at

Gabe Black 51edd54738 ARM: Generalize armv7 as arm.
There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.

We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.

The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

Curt Brune 3c12cb0384 cbfstool:linux_trampoline: config CS and DS segment descriptors
The Linux trampoline code does not set up the segment descriptors for
__BOOT_CS and __BOOT_DS as described in the Linux kernel
documentation:

  ... a GDT must be loaded with the descriptors for selectors
  __BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G
  flat segment; __BOOT_CS must have execute/read permission, and
  __BOOT_DS must have read/write permission;

This is not a problem when launching a Linux payload from coreboot, as
coreboot configures the segment descriptors at selectors 0x10 and
0x18.  Coreboot configures these selectors in the ramstage to match
what the Linux kernel expects (see
coreboot/src/arch/x86/lib/c_start.S).

When the cbfs payload is launched in other environments, SeaBIOS for
example, the segment descriptors are configured differently and the
cbfs Linux payload does not work.

If the cbfs Linux payload is to be used in multiple environments
should the trampoline needs to take care of the descriptors that Linux
requires.

This patch updates the Linux trampoline code to configure the 4G flat
descriptors that Linux expects.  The configuration is borrowed from
the descriptor configs in coreboot/src/arch/x86/lib/c_start.S for
selectors 0x10 and 0x18.

The linux_trampoline code is slightly refractored by defining the
trampoline entry address, 0x40000, as TRAMPOLINE_ENTRY_LOC.  This
definition is moved into a separate header file, linux_trampoline.h.
This header file is now included by both the trampoline assembly
language code and the trampoline loader C code.

The trampoline assembly language code can now use TRAMPOLINE_ENTRY_LOC
as scratch space for the sgdt CPU instruction.

Testing Done:

Verified the Linux payload is booted correctly in the following
environments:

1.  Coreboot -> Linux Payload

2.  Coreboot -> SeaBIOS -> Linux Payload: (previously did not work)

Aaron Durbin 518a322d58 rmodtool: correct final memory size calculation
Apparently when I originally wrote this I confused myself to no end.
The code/data of an rmodule has a set memory size which is associated
with the .payload section. The relocation entries may increase the
overall footprint of the memory size if the rmodule has no bss but
a lot of relocations. Therefore, just compare relocation entries size
plus the file size of the .payload section with the memory size of the
paylod section. The .empty section is added only when we have not met
the final target size.

Paul Menzel 470c37c372 util/cbfstool: Use `%zu` instead of `%ld` for size_t arguments
cbfstool fails to built under 32-bit platforms since commit

    aa2f739a cbfs: fix issues with word size and endianness.

due to the use of '%ld' format specifier on size_t, which on these
platforms is only 32-bit.

No error is seen though, when cbfstool is built, when building a coreboot
image, where it is put in `build/cbfstool`.

Use the length modifier `z` for size_t arguments, and cast to size_t where
appropriate.

Aaron Durbin 4f3bb801ed cbfstool: provide structure to linux payload builder
This change started with tracking down a bug where the trampoline
size was not being taken into account for sizing the output buffer
leading to a heap corruption.  I was having a hard time keeping
track of what num_segments actually tracked as well as what parts
were being placed in the output buffer. Here's my attempt at
hopefully providing more clarity.

This change doesn't crash when adding a bzImage:
$ dd if=/dev/zero of=bb.bin bs=64 count=1
$ ./cbfstool tmp.rom create -s 4M -B bb.bin -m x86 -a 64

Aaron Durbin 4fde5a66b4 util: add rmodtool for parsing ELF files to rmodules
The current implementation of creating rmodules relies
on invoking the linker in a certain manner with the
relocations overlaid on the BSS section. It's not really
surprising that the linker doesn't always behave the way
one wants depending on the linker used and the architecture.
Instead, introduce rmodtool which takes an ELF file as an
input, parses it, and creates a new ELF file in the format
the rmodule loader expects.

There isn't smart merging of the sections into a single PT_LOAD

This change adds a header serialization function. Programmers can thus just
set up a header as needed, without worrying about forgetting if and how to
use the [hn]to[hn]* functions.

In the long term, we will work to remove swab.h, i.e. we need to get to the
point where programmers don't have to try to remember [hn]to[nh]* and where
it goes. To date, even the best programmers we have have made an error with

Ronald G. Minnich a8a133ded3 Add section header parsing and use it in the mk-payload step
This completes the improvements to the ELF file parsing code.  We can
now parse section headers too, across all 4 combinations of word size
and endianness. I had hoped to completely remove the use of htonl
until I found it in cbfs_image.c. That's a battle for another day.

There's now a handy macro to create magic numbers in host byte order.
I'm using it for all the PAYLOAD_SEGMENT_* constants and maybe
we can use it for the others too, but this is sensitive code and
I'd rather change one thing at a time.

To maximize the ease of use for users, elf parsing is accomplished with
just one function:

int
elf_headers(const struct buffer *pinput,
	    Elf64_Ehdr *ehdr,
	    Elf64_Phdr **pphdr,
	    Elf64_Shdr **pshdr)

which requires the ehdr and pphdr pointers to be non-NULL, but allows
the pshdr to be NULL. If pshdr is NULL, the code will not try to read
in section headers.

To satisfy our powerful scripts, I had to remove the ^M from an unrelated
microcode file.

BUG=None
TEST=Build a peppy image (known to boot) with old and new versions and verify they are bit-for-bit the same. This was also fully tested across all chromebooks for building and booting and running chromeos.

Alexandru Gagniuc 9ad52fe56e cbfstool/lzma: Avoid use of typedef with structs and enums
When typedef is used with structs, enums, and to create new typenames,
readability suffers. As such, restrict use of typedefs only to
creating new data types.

The 80 character limit is intentionally ignored in this patch in order
to make reviewing easier.

Ronald G. Minnich aa2f739ae8 cbfs: fix issues with word size and endianness.
Add XDR functions and use them to convert the ELF headers
to native headers, using the Elf64 structs to ensure we accomodate
all word sizes. Also, use these XDR functions for output.

This may seem overly complex but it turned out to be much the easiest
way to do this. Note that the basic elf parsing function
in cbfs-mkstage.c now works over all ELF files, for all architectures,
endian, and word size combinations. At the same time, the basic elf
parsing in cbfs-mkstage.c is a loop that has no architecture-specific
conditionals.

Add -g to the LDFLAGS while we're here. It's on the CFLAGS so there is
no harm done.

This code has been tested on all chromebooks that use coreboot to date.

I added most of the extra checks from ChromeOS and they triggered a
lot of warnings, hence the other changes. I had to take -Wshadow back
out due to the many errors it triggers in LZMA.

BUG=None
TEST=Build and boot for Peppy; works fine. Build and boot for nyan,
     works fine. Build for qemu targets and armv8 targets.
BRANCH=None

Aaron Durbin 1ebc7e943b cbfstool: correct size left calculation for "empty" entries
After removing a file sandwiched between two other files, that file
could no longer be re-added at the same location. cbfstool tried to
add the file, and a new "empty" entry, which, together, would no
longer fit, so it continued checking for the next available space.

Change the behavior to add the file if there is enough space for the
file alone, then only add the "empty" entry if there is enough space
for it.
