Martin Roth 2ba837d8c7 xcompile: Quote variables to prevent globbing and splitting.
Quoting variables prevents word splitting and glob expansion, and
prevents the script from breaking when input contains spaces, line
feeds, glob characters and such.

See shellcheck warning SC2086

Martin Roth c4b684ebee xcompile: Put compiler variables outside of 'if' to allow checking
In order to be able to check the compiler versions, we need to be
able to access the compiler variables.  Move the original assignments
outside of the GCC check, and assign either the GCC or CLANG compiler
to the actual CC_ environment variable later.  This ends up with the
same value set, while allowing the compiler versions to be checked.

Julius Werner 4bfa29e947 arm64: xcompile: Add support for A53 erratum 843419
This patch adds support to enable a linker workaround to a hardware
erratum on some early Cortex-A53 revisions. Since the linker option was
added very recently, we use xcompile to test whether the toolchain
supports it first. It is also guarded by a Kconfig since only a few
ARM64 SoCs will need this and it incurs a performance penalty.

Martin Roth 1fff0d26f8 xcompile: Force localization of objdump to C
In testing other localization changes, I found that I couldn't build
anymore because xcompile wasn't picking up my toolchain.  I traced it
to the regex comparison of '.*format \(.[a-z0-9-]*\)' to the string
'formato del fichero elf32-i386'.  Forcing the localization of
objdump to C before doing the comparison fixes the issue.

Paul Kocialkowski 15dd6c2fa3 xcompile: crossgcc lookup in parent paths, for painless libpayload support
libpayload is calling the xcompile script from payloads/libpayload, so the
script never finds the path on its own and has to be fed the right XGCCPATH by
hand.

This makes xcompile look for the parent path too, so that it can find the
crossgcc toolchains when called from libpayload.

This requires a simple change to the top level xcompile to understand

them will occur at the same time)

libpayload's .xcompile target was moved later so that it can make use
of $(top)

Stefan Reinauer 4c8fa2aad2 Unconditionally compile romstage with -Wa,--divide
The option --divide is required by our assembler to ensure that
'/' is not parsed as a comment sign but as a division, because
some of the cache as ram code is using divisions.

The --divide parameter has been part of the GNU as since binutils 2.17.
Hence, compile romstage (which contains cache as ram init) with
-Wa,--divide unconditionally instead of probing for it and adding it to
all compiler invocations (because that is causing random trouble with
clang when compiling the SMM code and calling gcc with --divide instead of
-Wa,--divide)

Stefan Reinauer 8ef928af4e xcompile: Fix compiler invocation in testcc
While for GCC targets the compiler is just defined as a single
binary, for clang it is defined as a binary and some options, e.g.:
  clang -target i386-elf -ccc-gcc-name i386-elf-gcc

When executing the compiler with "$1", the shell will look for a
binary with the above name (instead of just clang) and always fail
detection of any CFLAGS.

By adding -c we prevent the compiler from failing because it can't
link a user space program (when what we're looking for, is whether
a specific compiler flag can be used to compile a coreboot object
file)

Patrick Georgi b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

Paul Menzel e9b7e25708 util/xcompile/xcompile: Allow to override `HOSTCC` variable
Currently `xcompile` generates `.xcompile` with the following at the
top.

	# platform agnostic and host tools
	IASL:=iasl
	HOSTCC:=gcc

The assignment `:=` doesn’t allow to override the variable. So use `?=`
instead so the host compiler can be passed to coreboot.

	HOSTCC=gcc-5 make

Note, that this is just a hack, as the existence of `gcc` is checked
beforehand.

Vadim Bendebury 05a8472900 xcompile: improve mips toolchain handling
The mips toolchain used by coreboot so far comes from Chrome OS chroot
and is built explicitly for little endian code generation.

Other flavors of MIPS toolchain usually generate big endian code by
default and require command line options to switch to little endian
mode.

This patch adds another variable to the set of compiler flags examined
to determine compiler compatibility. This results in adding another
nested for loop in test_architecture(). To avoid the need to break
from different levels of nesting, processing of the successful case is
taken out from test_architecture().

With this change the Mentor Graphics provided mips GCC toolchain is
accepted by xcompile, resulting in the following output:

 ARCH_SUPPORTED+=mips
 SUBARCH_SUPPORTED+=mips mipsel
 CC_mips:=mips-linux-gnu-gcc
 CFLAGS_mips:= -Wno-unused-but-set-variable  -fno-stack-protector -Wl,--build-id=none -mno-abicalls -fno-pic -EL
 CPP_mips:=mips-linux-gnu-cpp
 AS_mips:=mips-linux-gnu-as
 LD_mips:=mips-linux-gnu-ld
 NM_mips:=mips-linux-gnu-nm

 STRIP_mips:=mips-linux-gnu-strip

elf32-tradlittlemips format, whereas readily available tools outside
of chroot generate images of elf32-littlemips format. Both of these

This patch allows to specify multiple formats per architecture, any

Gabe Black 51edd54738 ARM: Generalize armv7 as arm.
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.

free to pick whatever defaults it is using at the time of

Not properly specifying -march then opens up the use of SSE
