Therefore, adapt our build system and documentation. Upstream is less
strict at this time, but there's a proposed patch that got imported.

https://review.coreboot.org/c/coreboot/+/11272 can be detected,
which I tested by manually breaking our Kconfig in a similar way.

While having select statements in Kconfig.name files is valid in the
syntax of the Kconfig language, having the selections split between the
normal Kconfig file and Kconfig.name files makes it harder to see what's
going on.
Kconfig.name files will now be limited to their original purpose of
selecting a particular board or board variant, not actually configuring
that board.

Some boards (e.g. prodrive/hermes) that do not provide their own FMAP
and therefore have been generated by the build system (+ ifdtool)
experience a failure when trying to build with an IFD that contains
regions which do not have equivalent fmap names (set to NULL).
Therefore add a NULL check for the fmapname and ignore the region if we
do not have an fmapname.

To see which Kconfig symbols are actually used, and to verify that
they're used correctly, kconfig_lint scans the C code. It gives an error
if it sees a CONFIG(symbol) where the symbol doesn't exist.
This creates a problem when a C preprocessor macro is created to match
multiple Kconfig symbols. The simple solution here is to just ignore
those C preprocessor macro definitions as beyond the scope of this
linter.

The linker can make relocation entries of a symbol which has a value
of zero point to the undefined symbol entry. It is permitted since
when the symbol value is zero as the documentation of the relocation
entry `r_info' field states:
"If the index is STN_UNDEF, the undefined symbol index, the relocation
uses 0 as the symbol value."
The ELF binary does not really have any missing symbols. It is an
optimization as the symbol points to the undefined symbol because its
value is zero.
A typical way to hit this cbfstool limitation is to define an empty
region using the REGION macro in the linker script. Here is an
example if we assume `CONFIG_MY_REGION' is set to 0:
.car.data {
[...]
REGION(my_region, CONFIG_MY_REGION_SIZE)
[...]
}
A region is defined as follow:
#define REGION_SIZE(name) ((size_t)_##name##_size)
#define DECLARE_REGION(name) \
extern u8 _##name[]; \
extern u8 _e##name[]; \
extern u8 _##name##_size[];
So the size of the region is actually the address of the
`_##name##_size' symbol. Therefore, the `_my_region_size' symbol
address is zero and the linker can make the relocation entry of this
symbol point to the undefined symbol index.
In such a situation, cbfstool hits a segmentation fault when it
attempts to relocate the symbol in `parse_elf_to_xip_stage()'
function. We resolves this issue by making cbfstool skips relocation
entries pointing to the undefined symbol similarly to the way it skips
relocation relative to absolute symbols. A symbol which value is zero
can be considered an absolute symbol and therefore should not be
relocated.
Of course, we could argue that we could just prevent the declaration
of an empty region as illustrated in the following example:
.car.data {
[...]
#if CONFIG_MY_REGION_SIZE > 0
REGION(my_region, CONFIG_MY_REGION_SIZE)
#endif
[...]
}
However, this is not a satisfying solution because:
1. It requires to add unnecessary code in the linker script as an empty
region is a valid declaration. Such a workaround requires the code
using it to mark the region symbols as weak symbols to handle the
situation where the region is not defined.
2. There could be other situations which have yet to be uncovered which
would lead the same cbfstool crash.
3. A binary with an empty region is a valid ELF file and cbfstool
should not crash when it is asked to create an eXecute-In-Place stage
out of it.

Revise the Makefile.inc rules for generating FMD parser files.
- lex: If --header-file is supported then the lex (usually flex) should
also support '-o' so we don't need to do redirection (-t).
- yacc: Bison is already required by bincfg and sconfig so we
can change the default parser compiler to Bison. That also
allows us to use -o and --defines to override the output files.
- both: Line directives are only helpful when debugging the scanner and
the parser, so we should remove them to get better git diff
results (-L for lex, -l for bison).
Also regenerated the shipped files with latest version of flex (2.6.4)
and bison (3.8.2).

The mapped windows is up to 16M. Even if the flash size is 32MB, it is
not mapped at 0xFE000000.
So using "0xFFFFFFFF - rom_size + 1" to get the "rom_base_address" can
only explain well when rom_size is less or equal to 16MB. For larger
size, it is not physically correct (Even though it can get expected
result).
If the flash size is larger than 16M, we assume the given addresses
are already relative ones. So we don't need the physical base address
any more.
This commit is part of a series of patches to support 32/64M flash.
