Patrick Georgi 9de060fd34 libpayload: Use volatile pointers in {read,write}{8,16,32,64}
This is already the case on x86 but not on the ARM platforms, and
{read,write}[bwl] are using volatile pointers, too, so follow suit.

Patrick Georgi 6b5bc77c9b treewide: Remove "this file is part of" lines
Stefan thinks they don't add value.

Command used:
sed -i -e '/file is part of /d' $(git grep "file is part of " |egrep ":( */\*.*\*/\$|#|;#|-- | *\* )" | cut -d: -f1 |grep -v crossgcc |grep -v gcov | grep -v /elf.h |grep -v nvramtool)

The exceptions are for:
 - crossgcc (patch file)
 - gcov (imported from gcc)
 - elf.h (imported from GNU's libc)
 - nvramtool (more complicated header)

The removed lines are:
-       fmt.Fprintln(f, "/* This file is part of the coreboot project. */")
-# This file is part of a set of unofficial pre-commit hooks available

Julius Werner 8a1d11f797 libpayload: Expand setbits_le32() and fix readl() const-ness
setbits_le32() is not really arch-specific... the arch-specific part of
accessing memory is wrapped by readl() and writel(), and the endianness
can be accounted for with the right macros. Generalize the definitions,
add a be32 version and move them to endian.h so that all platforms can
use them. Also include endian.h from libpayload.h so we won't update any
payload's old use of the macros (endianness is something useful enough
to always have avalable anyway, and shouldn't clash with other things).
This also fixes a bug where these macros would only be available if
libpayload-config.h had been independently included before.

Also fix a bug with readl() macros on all archs where they refused to
work on const pointers (which they should).

Vadim Bendebury bc8b4fad1e libpayload: Introduce bit manipulation macros
Some drivers being ported to depthcharge use io bit manipulation
macros. The libpayload include file seems the most appropriate place
to keep these macros in. There is no common io.h file across
architectures, the x86 version could be added later if required.

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.
