Currently, qemu_arm_defconfig and qemu_arm64_defconfig only work with
the 'highmem=off' parameter passed to QEMU's virt machine. The reason is
that when 'highmem' is not disabled, QEMU appends 64-bit a memory
resource to the PCI controller's regions property in DT in addition to
the 32-bit PCI memory window in low memory. And the current DT parsing
code picks the last (thus the 64-bit one) memory resource, whose address
eventually gets silently truncated to 32 bits because
CONFIG_SYS_PCI_64BIT is not set, which obviously causes PCI to break.
Avoid this problem by ignoring memory regions whose addresses are above
the 32-bit boundary when CONFIG_SYS_PCI_64BIT is not set.

TPM commands are much easier to read/write with these macros that will
transform words or integers into byte strings. This way, there is no
need to call pack_byte_string() while all variable length in a command
are known (and at must 4 bytes, which is a lot of them).

tpm: prepare introduction of TPMv2.x support in Kconfig
Because both major revisions are not compatible at all, let's make them
mutually exclusive in Kconfig. This way we will be sure, when using a
command or a library function that it is supported by the right
revision.
Current drivers are currently prefixed by "tpm_", we will prefix TPMv2.x
files by "tpm2_" to make the distinction without moving everything.
The Kconfig menu about TPM drivers is now divided into two sections, one
for each specification. Compliant drivers with one specification will
only show up if this specification _only_ has been selected, otherwise a
comment is displayed.
Once a driver is selected by the user, it selects automatically a
boolean value, that is needed in order to activate the TPM commands.
Selecting the TPM commands will automatically select the right
command/library files.

rpi: Change load addresses to make more room for the kernel & DTB
As of Linux 4.16, a multiplatform AArch64 kernel with our distro config
takes 26M. The current space reservation leaves only 17M for the kernel
and if it goes over it, the initrd gets overwritten when loading the
kernel from the filesystem.
A similar problem happens on ARMv7 with the DTBs taken from the
downstream Raspberry Pi foundation kernel. I guess they compile them
with DT overlay support enabled which grows them just enough.
Fix both of these problems by rewriting the memory map, which now allows
kernels to be up to 36M and DTBs up to 1M. Also the comment block was
kind of obsolete ever since the introduction of AArch64 support and the
firmware-loaded DTB doesn't get placed at 0x100 anymore either, so that
is fixed as well.
