When updating firmware, it is very often that we may want to preserve
few sections, for example vital product data (VPD) including serial
number, calibration data and cache. A firmware updater has to hard-code
the section names that need to be preserved and is hard to maintain.
A better approach is to specify that in FMAP area flags (the `area_flag`
field) using FMAP_AREA_PRESERVE. With this patchset, a FMD parser flag
"PRESERVE" is introduced and will be converted to FMAP_AREA_PRESERVE
when generating FMAP data (by fmap_from_fmd.c).
For example, The FMD statement:
RO_VPD(PRESERVE)@0x0 16k
will generate an FMAP firmware section that:
area_name = "RO_VPD"
area_offset = 0
area_size = 16384
area_flags = FMAP_AREA_PRESERVE
BUG=chromium:936768
TEST=make; boots on x86 "google/eve" and arm "google/kukui" devices
Manually added 'PRESERVE' to some FMD files, and verify (by running
fmap.py) the output coreboot.rom has FMAP_AREA_PRESERVE set

The idea of "annotation" for firmware sections was pretty flexible, but
in future we will want multiple attributes applied to same area. For
example, indicate the section must be preserved when updating firmware
so serial number or MAC address can be preserved.
The solution here is to extend annotation so it can take multiple
identifiers (flags) in a row. For example, to declare a 64KB COREBOOT
section as CBFS using annotation:
COREBOOT(CBFS)@0x0 64k
If there's a new flag "PRESERVE" indicating the section must be
preserved before update, we can declare it following CBFS flag:
COREBOOT(CBFS PRESERVE)@0x0 64k
The flags are directly parsed in fmd_parser, and stored in an union
flashmap_flags. Output modules can choose to ignore or process the
flags.
Currently the only supported flag is "CBFS" (for backward compatible
with annotation). There will be more new flags in follow up patches.

When updating firmware, we may need to preserve some sections like VPD,
calibration data, ... etc. The logic can be hard-coded in updater as a
list of known names, but a better solution is to have that directly
declared inside FMAP area flags.
To do that, the first step is to apply the changes in flash map
(http://crosreview.com/1493767). A new FMAP_AREA_PRESERVE is now
defined and will be set in future with new syntax in FMD parser.

This patch adds two minor improvements to the way cbfs-compression-tool
parses the compression algorithm type that is passed through the -t
option of the 'compress' subcommand. These improvements are intended
to prevent accidents and unexpected behavior when using the
cbfs-compression-tool, in particular in automated contexts such as a
Makefile rule.
In the first part of this patch, a return statement is inserted after
the 'if (algo->name == NULL)' check of the compress() function. This
causes the function to exit immediately and subsequently abort the
program when the algorithm type was not detected correctly. Previously,
execution would continue with the 'algo' pointer pointing to the zeroed
out stopper entry of the types_cbfs_compression[] array. The ultimate
effect of this would be to pass 0 as 'algo->type' to the
compression_function() function, which happens to be the same
enumeration value as is used for CBFS_COMPRESS_NONE, leading to a valid
compression function result that matches the behavior of no compression.
Thus, if a script calling cbfs-compression-tool compress contained a
typo in the -t parameter, it would continue running with an unintended
compression result rather than immediately exiting cleanly.
In the second part of this patch, the strcmp() function is replaced with
strcasecmp() when comparing 'algo->name' with the 'algoname' parameter
that was passed to the compress() function. strcasecmp() uses an
identical function signature as strcmp() and is thus suitable as a
drop-in replacement, but it differs in behavior: rather than only
returning a result of 0 when the two NULL-terminated input strings are
character by character identical, the strcasecmp() function applies a
weaker concept of identity where characters of the latin alphabet
(hexadecimal ranges 0x41 through 0x5a and 0x61 through 0x7a) are also
considered identical to other characters that differ from them only in
their case. This causes the -t parameter of cbfs-compression-tool
compress to also accept lowercase spellings of the available compression
algorithms, such as "lz4" instead of "LZ4" and "lzma" instead of "LZMA".
As an unintended but harmless side-effect, mixed-case spellings such as
"lZ4" or "LZmA" will also be recognized as valid compression algorithms.
(Note that since the character "4" (hexadecimal 0x34) of the "LZ4"
compression type name is not part of the above-mentioned ranges of latin
alphabet characters, no new substitutions become valid for that part of
the "LZ4" string with this patch.)

This is useful when you don't have usb debugging, and
UART lines are hard to find. Since a failure to boot would
require a hardware flasher anyways, we can get the log
at the same time.
This feature should only be used when no alternative is
found and only when we can't boot the system, because
excessive writes to the flash is not recommended.
This has been tested on purism/librem13 v2 and librem 15 v3 which

This is tested in qemu and fixes the observed problem
that 974f221c84b05b1dc2f5ea50dc16d2a9d1e95eda and later would not
boot, and would in fact fail in head_64.S.

This patch adds functionality to compile a C data structure into a raw
binary file, add it to CBFS and allow coreboot to load it at runtime.
This is useful in all cases where we need to be able to have several
larger data sets available in an image, but will only require a small
subset of them at boot (a classic example would be DRAM parameters) or
only require it in certain boot modes. This allows us to load less data
from flash and increase boot speed compared to solutions that compile
all data sets into a stage.
Each structure has to be defined in a separate .c file which contains no
functions and only a single global variable. The data type must be
serialization safe (composed of only fixed-width types, paying attention
to padding). It must be added to CBFS in a Makefile with the 'struct'
file processor.

If some error happens in cbfs_payload_make_elf, the code jumps to "out",
and elf_writer_destroy(ew) is called. This may happen before an elf
writer is allocated.
To avoid accessing an uninitialized pointer, initialize ew to NULL;
elf_writer_destroy will perform no action in this case.

The interface to strtoul() is a weird mess. It may or may not set errno
if no conversion is done. So check for empty strings and trailing
characters.

The name 'bpdt_size' is used for a function as well as ia local variable.
As ifwitool is compiled using HOSTCC, there can be an older gcc version
used for the compilation. With gcc version 4.4.7 I get the following
error: declaration of 'bpdt_size' shadows a global declaration
To fix it, rename the function to get_bpdt_size so that names are
unique now.
