This reverts commit 626ba097a2.
This change was submitted under the incorrect assumption that there was
agreement on a coding style change. There wasn't, so while the issue is
under discussion we should revert to the previous status quo.
Making clang-format honor the line length is a separate issue from
changing the line length, and can be reuploaded as a separate CL.

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

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.

VBT on Intel(R) systems is available via sysfs as
/sys/kernel/debug/dri/0/i915_vbt
However the size of this file reads as 0 causing
intelvbttool to fail. This patch implements incremental reads
with realloc for such cases or whenever the file size is not
available (e.g. reading from stdin).
After this patch is applied, intelvbttool can be used as follows:
sudo intelvbttool -f /sys/kernel/debug/dri/0/i915_vbt -d

Put the FMAP FMAP region right above the coreboot CBFS region.
The other regions like RW_MRC_CACHE and CONSOLE often have alignment
requirements so it makes sense to put those on top. This also
simplifies the code the generate the default fmap a little.

The coreboot table entry containing the memory entries can have
fields unnaturally aligned in memory. Therefore one needs to perform
an aligned_memcpy() so that it doesn't cause faults on certain
architectures that assume naturally aligned accesses.
