While parsing the section and program headers ensure the
locations of their contents are within the elf file proper.

Aaron Durbin b1b5118c71 cbfstool: elfheaders: use proper parameters to calloc()
Though the result doesn't matter much, the callers of calloc()
should order the parameters correctly. i.e. the first paramter
is the number of elements in an array and the second is the
size of each element.

Aaron Durbin 54ef306377 cbfstool: add eflparsing.h
elfparsing.h serves as the header to working with the elf
parser. Additionally, only include what is needed by the other
files. Many had no reason to be including elf.h aside from fixing
compilation problems when including cbfs.h.

Alexandru Gagniuc 0c54bfa0ee Revert "boardstatus/towiki: Declare southbridge=northbridge=cpu on SOCs"
This reverts commit b845636ce6.
This commit changed the board status script to describe all boards in
terms of x86 terminology, such as CPU->southbridge->northbridge.

This terminology does not apply to a number of SoCs, in which the
buses are not connected via successive bridges, and as such it is
misleading and misguided to describe ideas of southbridge and
northbridge for these devices.

Chris Douglass 4eabe1e4e1 util/ifdtool: add option to change flash layout
The new option "--newlayout <file>" will read <file> in flashrom's
layout format and copy flash regions from the current flash image
file to a new flash image file.

If a region grows, the padding is added at the beginning of the target
region in the new file so that the data is "right-aligned" to the
end of the region.

If a region shrinks, a warning is given and the tail end of existing
data is copied to the target region in the new file.

Regions of zero or negative size are ignored. (In the example below
00fff000:00000fff regions are an artifact of the address encoding
in the register fields.)

Example Usage:

Given a flash image for a board with a Sandy Bridge processor and
Intel 6-Series chipset in the file vpx7654.bin

ifdtool --layout layout.txt vpx7564.bin
will yield the file layout.txt:
	00000000:00000fff fd
	00180000:003fffff bios
	00001000:0017ffff me
	00fff000:00000fff gbe
	00fff000:00000fff pd

Notice that the "bios" portion extends to the end of the 4MB flash.
It may be edited to extend the bios portion to consume to the extent
of an 8MB flash. like layout2.txt:
	00000000:00000fff fd
	00180000:007fffff bios
	00001000:0017ffff me
	00fff000:00000fff gbe
	00fff000:00000fff pd

ifdtool --newlayout layout.txt vpx7654.bin
will create a file vpx7654.bin.new that is 8MB.

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
those functions, and those errors have persisted for 6 or 7 years now. It's
very easy to make that mistake.

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

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

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.

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.
