Yi Chou 1739c99efe libpayload: Move ttb_buffer to a standalone section
When cleaning the sensitive data in the memory, we will want to prevent
zero out the content of tbb_buffer. Move the ttb_buffer to a standalone
section will simplify the problem.

Michael Walle 492d55fa46 libpayload: arm64: fix OUTPUT_ARCH()
There is no bfd "arm64". The correct bfdname is "aarch64". Fix it. With
this change libpayload will build with the AArch64 GCC.

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
-/* This file is part of coreboot */

Julius Werner 5c0e72ff99 libpayload: arm64: Make exception handling closer to arm32
This patch reworks the arm64 exception handling to be more similar to
how it works on arm32. This includes a bunch of features like actually
saving and restoring more exception state in the exception_state
structure and supporting the same sort of partial reentrancy that is
useful for GDB. Since there's no instruction to directly load into or
store out of SP on arm64, we can't do quite the same thing where we use
that to read an exception_state_ptr variable right after exception entry
when no other register is available. But we can do something very
similar by (ab-)using the "high" stack pointer (SP_EL2) as a pointer to
the exception_state struct and providing a function to change it.
