Hung-Te Lin 4708612061 fmap: Add FMAP_AREA_PRESERVE
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.

Put the FMAP FMAP region right above the coreboot CBFS region.

requirements so it makes sense to put those on top. This also
simplifies the code the generate the default fmap a little.

When extracting a payload from CBFS, ignore compression fields for
these types of payload segments:
  - PAYLOAD_SEGMENT_ENTRY
  - PAYLOAD_SEGMENT_BSS
  - PAYLOAD_SEGMENT_PARAMS

These types of payload segments cannot be compressed, and in certain
cases are being erroneously labeled as compressed, causing errors
when extracting the payload.

For an example of this problem, see creation of PAYLOAD_SEGMENT_ENTRY
segments in cbfs-mkpayload.c, where the only field that is written to
is |load_addr|.

Also, add a linebreak to an ERROR line.

The linux trampoline was modifying the existing GDT
to add the 0x10 and 0x18 descriptors for Linux.
This will not work when the existing GDT is in ROM.

Change the code to set up a new GDT in what we know to be
RAM.

Tested by booting a linux payload. The main reason this works
is that Linux almost immediately loads its own GDT and then
segment registers. This GDT is a very temporary bridge.

Note that none of this change used to be necessary; the coreboot
GDT was originally compatible with Linux (ca 2000);
then Linux changed.

Werner Zeh a7835c462e cbfstool: Use endian.h and functions from commonlib
The endian conversion function be32toh() is defined in
src/include/endian.h, however this file is not used for cbfstool
compilation. Currently the one provided by the host is used and if the
host does not provide this endian.h file, the build will fail.
However, we do have endian conversion functions in commonlib/endian.h
which is available for cbfstool compilation.

Switch from be32toh() to read_be32() in order to avoid relying on a
host provided include file.
We use functions from commonlib/endian.h already in cbfstool.

Patrick Rudolph 7ee05eddf1 util/cbfstool: Support FIT payloads
In order to support booting a GNU/Linux payload on non x86, the FIT format
should be used, as it is the defacto standard on ARM.
Due to greater complexity of FIT it is not converted to simple ELF format.

Add support for autodecting FIT payloads and add them as new CBFS_TYPE 'fit'.
The payload is included as is, with no special header.
The code can determine the type at runtime using the CBFS_TYPE field.
Support for parsing FIT payloads in coreboot is added in a follow on
commit.
Compression of FIT payloads is not supported, as the FIT sections might be
compressed itself.

Starting at this point a CBFS payload/ can be either of type FIT or SELF.

Tested on Cavium SoC.

Julius Werner 88f4e08acf cbfs-compression-tool: Add raw compression support
This patch adds a new "rawcompress" command to cbfs-compression-tool,
that works exactly the same as "compress" except that it doesn't add the
custom 8-byte header to the file. This can be useful if you need to
compress something into a format that coreboot's decompression routines
can work with, but it's not supposed to go into CBFS.

Julius Werner ee87885343 cbfs-compression-tool: Fix minor edge cases in algorithm type parsing
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.)
