Allow add-stage to have an optional parameter for ignoring any section. This is
required to ensure proper operation of elf_to_stage in case of loadable segments
with zero filesize.

Add support for creating ARM rmodules. There are 3 expected
relocations for an ARM rmodule:
- R_ARM_ABS32
- R_ARM_THM_PC22
- R_ARM_THM_JUMP24
R_ARM_ABS32 is the only type that needs to emitted for relocation
as the other 2 are relative relocations.

The LZMA compression algorithm, currently the only one available, will fail
if you ask it to write more data to the output than you've given it space for.
The code that calls into LZMA allocates an output buffer the same size as the
input, so if compression increases the size of the output the call will fail.
The caller(s) were written to assume that the call succeeded and check the
returned length to see if the size would have increased, but that will never
happen with LZMA.
Rather than try to rework the LZMA library to dynamically resize the output
buffer or try to guess what the maximal size the data could expand to is, this
change makes the caller simply print a warning and disable compression if the
call failed for some reason.
This may lead to images that are larger than necessary if compression fails
for some other reason and the user doesn't notice, but since compression
errors were ignored entirely until very recently that will hopefully not be
a problem in practice, and we should be guaranteed to at least produce a
correct image.

When compression fails for whatever reason, the caller should know about it
rather than blindly assuming it worked correctly. That can prevent half
compressed data from ending up in the image.
This is currently happening for a segment of depthcharge which is triggering
a failure in LZMA. The size of the "compressed" data is never set and is
recorded as zero, and that segment effectively isn't loaded during boot.

The aarch64 is not really an arm variant, it's sufficiently
different that it can be considered (for purposes of cbfs, certainly)
to be a new architecture.
Add a constant in cbfs.h and strings to correspond to it.
Note that with the new cbfstool support that we added earlier,
the actual use of aarch64 ELF files actually "just works" (at
least when tested earlier).

There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.
We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.
The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

The Linux trampoline code does not set up the segment descriptors for
__BOOT_CS and __BOOT_DS as described in the Linux kernel
documentation:
... a GDT must be loaded with the descriptors for selectors
__BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G
flat segment; __BOOT_CS must have execute/read permission, and
__BOOT_DS must have read/write permission;
This is not a problem when launching a Linux payload from coreboot, as
coreboot configures the segment descriptors at selectors 0x10 and
0x18. Coreboot configures these selectors in the ramstage to match
what the Linux kernel expects (see
coreboot/src/arch/x86/lib/c_start.S).
When the cbfs payload is launched in other environments, SeaBIOS for
example, the segment descriptors are configured differently and the
cbfs Linux payload does not work.
If the cbfs Linux payload is to be used in multiple environments
should the trampoline needs to take care of the descriptors that Linux
requires.
This patch updates the Linux trampoline code to configure the 4G flat
descriptors that Linux expects. The configuration is borrowed from
the descriptor configs in coreboot/src/arch/x86/lib/c_start.S for
selectors 0x10 and 0x18.
The linux_trampoline code is slightly refractored by defining the
trampoline entry address, 0x40000, as TRAMPOLINE_ENTRY_LOC. This
definition is moved into a separate header file, linux_trampoline.h.
This header file is now included by both the trampoline assembly
language code and the trampoline loader C code.
The trampoline assembly language code can now use TRAMPOLINE_ENTRY_LOC
as scratch space for the sgdt CPU instruction.
Testing Done:
Verified the Linux payload is booted correctly in the following
environments:
1. Coreboot -> Linux Payload
2. Coreboot -> SeaBIOS -> Linux Payload: (previously did not work)

Apparently when I originally wrote this I confused myself to no end.
The code/data of an rmodule has a set memory size which is associated
with the .payload section. The relocation entries may increase the
overall footprint of the memory size if the rmodule has no bss but
a lot of relocations. Therefore, just compare relocation entries size
plus the file size of the .payload section with the memory size of the
paylod section. The .empty section is added only when we have not met
the final target size.

The current implementation of creating rmodules relies
on invoking the linker in a certain manner with the
relocations overlaid on the BSS section. It's not really
surprising that the linker doesn't always behave the way
one wants depending on the linker used and the architecture.
Instead, introduce rmodtool which takes an ELF file as an
input, parses it, and creates a new ELF file in the format
the rmodule loader expects.

there needs to be support for writing out ELF files. The
ELF writer is fairly simple. It accpets sections that can
be associated with an optional buffer (file data). For each
section flagged with SHF_ALLOC a PT_LOAD segment is generated.
There isn't smart merging of the sections into a single PT_LOAD
segment.

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

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.

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.

During the update_fit step, 'file_length' is used to determine how many
bytes are left in the CBFS file. It was decremented in a loop from an
array 'mcus[num_mcus].size', but 'num_mcus' was incremented right before.
Since 'mcus' is memset(0) externally, 'file_length' was never decremented.
The loop exited when it reached a dummy terminator, usually 48 bytes of 0
which are internationally added to microcode blobs in coreboot. However,
if that terminator is removed, the loop doesn't stop and continues until
it segfaults.

cbfstool usage change:
The "-a" parameter for "cbfstool locate" is switched to "-P/--page-size".
The "locate" command was used to find a place to store ELF stage image in one
memory page. Its argument "-a (alignment)" was actually specifying the page size
instead of doing memory address alignment. This can be confusing when people are
trying to put a blob in aligned location (ex, microcode needs to be aligned in
0x10), and see this:
cbfstool coreboot.rom locate -f test.bin -n test -a 0x40000
# output: 0x44, which does not look like aligned to 0x40000.
To prevent confusion, it's now switched to "-P/--page-size".

Right now cbfstool only accepts firmware volumes with

some magic values and the extended PE header are
different. With this patch, both IA32/x64 images are
supported. (No check is done whether the mainboard
actually supports 64bit CPUs, so careful!)
This needs another patch to Tiano Core that switches
to long mode after jumping to the 64bit entry point.
Right now that code assumes we're already in 64bit code
and the machine crashes.

Current cbfstool implementation is relying on global variables to pass processed
data, and the calculation of address is based on x86 architecture (ex, always
assuming 0x0000 as invalid address), not easy to be used on platforms without
top-aligned memory mapping. This CL is a first step to start a new cbfstool
without global variables, and to prevent assuming memory layout in x86 mode.
The first published APIs are for reading and writing existing CBFS ROM image
files (and to find file entries in a ROM file).
Read cbfs_image.h for detail usage of each API function.

Many functions in cbfstool need to deal with a memory buffer - both location and
size. Right now it's made by different ways: for ROM image using global variable
(romsize, master_header); and in cbfs-* using return value for size and char**
to return memory location.
This may cause bugs like assuming incorrect return types, ex:
uint32_t file_size = parse(); // which returns "-1" on error
if (file_size <= 0) { ...
And the parse error will never be caught.
We can simplify this by introducing a buffer API, to change
unsigned int do_something(char *input, size_t len, char **output, ...)
into
int do_something(struct buffer *input, struct buffer *output, ...)
The buffer API will be used by further commits.
