QEMU 3.0 introduced additional memory-mapped regions for PCI-E ECAM and
MMIO. Thus we need to add them to our MMU map or U-Boot will crash with
a Synchronous Abort during PCI-E probing when it tries to access the
unmapped ECAM memory area.

This patch renames the routine fdtdec_setup_memory_size()
to fdtdec_setup_mem_size_base() as it now fills the
mem base as well along with size.

Now that we have generic EFI payload support for all x86 boards,
drop the QEMU-specific one.

Now that PCI devices work with highmem-enabled QEMU emulation, bump up
the RAM size in the MMU tables to gain access to the full 255 GB of RAM
potential instead of the puny 3 GB.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

This adds support for '-machine virt' on AArch64. This is rather simple:
we just add TARGET_QEMU_ARM_xxBIT to select a few different Kconfig
symbols, provide the ARMv8 memory map from the board file and add a new
defconfig based on the 32-bit defconfig.

This board builds an U-Boot binary that is bootable with QEMU's 'virt'
machine on ARM. The minimal QEMU command line is:
qemu-system-arm -machine virt,highmem=off -bios u-boot.bin
(Note that the 'highmem=off' parameter to the 'virt' machine is required for
PCI to work in U-Boot.) This command line enables the following:
- u-boot.bin loaded and executing in the emulated flash at address 0x0
- A generated device tree blob placed at the start of RAM
- A freely configurable amount of RAM, described by the DTB
- A PL011 serial port, discoverable via the DTB
- An ARMv7 architected timer
- PSCI for rebooting the system
- A generic ECAM-based PCI host controller, discoverable via the DTB
Additionally, QEMU allows plugging a bunch of useful peripherals to the PCI bus.
The following ones are supported by both U-Boot and Linux:
- To add a Serial ATA disk via an Intel ICH9 AHCI controller, pass e.g.:
-drive if=none,file=disk.img,id=mydisk -device ich9-ahci,id=ahci -device ide-drive,drive=mydisk,bus=ahci.0
- To add an Intel E1000 network adapter, pass e.g.:
-net nic,model=e1000 -net user
- To add an EHCI-compliant USB host controller, pass e.g.:
-device usb-ehci,id=ehci
- To add a NVMe disk, pass e.g.:
-drive if=none,file=disk.img,id=mydisk -device nvme,drive=mydisk,serial=foo

Add a new board config which uses 64-bit U-Boot. Supported features
are the same as the other 64-bit board (Google Chromebook Link).
It is a start for us to test 64-bit U-Boot easily without the need
to access a real hardware.
Note CONFIG_SPL_ENV_SUPPORT is required for QEMU 64-bit as without
this the SPL build fails at the end. This is just a workaround as
CONFIG_SPL_ENV_SUPPORT is not needed at all.

lib/hashtable.c:382: undefined reference to 'env_flags_init'
make[1]: *** [spl/u-boot-spl] Error 1
Except those SPL options required by 64-bit, compared to 32-bit
config, the following options are different:
- CONFIG_SYS_MALLOC_F_LEN has to be increased to 0x1000 for SPL.
- CONFIG_DEBUG_UART has to be included due to the weird issue.
See TODO comments in arch/x86/cpu/x86_64/cpu.c:arch_setup_gd().
Once this issue gets fixed, debug uart can be optional.

This introduces two board defconfig files for generating EFI 32-bit
and 64-bit payloads, to run on QEMU x86 target.
With these in place, hopefully buildman will catch any build error
with EFI payload support on x86.
