Commit 6d439a4646, which added JSON configuration output, caused the
configuration headers to be generated at build-time instead of
configure-time. This broke CAmkES build systems which depend on
configuration headers in CAmkES files at configure-time.
This commit makes the configuration headers available at configure-time.

Without this patch, user-level programs have the ability to
map in the core-local interrupt controller on RISC-V platforms
which contains the memory-mapped registers for the core-local
timer the kernel uses. This is a level of privilege that
user-level programs should not have. Writing to the `mtime`
register is possible which can then affect the timer interrupts
are delivered to the kernel.

* Add help texts for all CLI options.
* Point to the manual in file header.
* Remove obsolete `--multifile_base` and `--c_defs` options. The former
is unused and the logic for it was removed in the previous commit.
The latter is not referenced in the code and has no effect. `
* Remove unused `mode` variable.

Add a `--form_file <file>` option to the bitfield generator for
printing a `/* generated from <file> */` message in a comment.
Use this option in cmake to provide the original source .bf file before
preprocessing so it's easier to find out where the corresponding
definitions are.

For verification flexible w.r.t kernel placement in physical memory, we
need to relate physBase as a named constant to its abstract equivalent.
Unfortunately, apart from enums, the C programming language does not
have real constants. The C parser follows the C standard and requires
enums constants to be storable as int, meaning without major overhaul
enums are not sufficient for storing word_t-sized memory addresses.
Since the linker scripts can't deal with static inline functions
in the constants they need (KERNEL_ELF_BASE and KERNEL_ELF_PADDR_BASE),
we provide the following preprocessor definitions for the linker
specifically:
* PHYS_BASE_RAW (the numerical value returned by physBase())
* KERNEL_ELF_BASE_RAW
* KERNEL_ELF_PADDR_BASE_RAW

gen_config.json provides a language-independent means of accessing the
kernel configuration. Before, gen_config.h was generated directly in
CMake. Now, gen_config.yaml is generated directly in CMake, and
gen_config.h and gen_config.json are derived from gen_config.yaml.

This adds support for the Pine64 Quartz64 and other devices based on
the Rockchip RK3566. The platform support is adapted from the
Rockpro64 code, except that the RK356x has A55 cores, and adjusting
for the fact that the ARM Generic Timer is the only on-chip timer
available.

kernel,bcm2711: Fix RPI4 address mapping
Fix build error and warnings by removing GPIO mapping
from overlay. Also as a note, don't add 'serial1' or 'ethernet'
here, because 'serial1' is already mapped to sel4 kernel by
'chosen' block in 'overlay-rpi4.dts', and the translation for
the 'ethernet' is done with 'ranges' property.

kernel,bcm2711: Fix memory area overlay DTS
First fix is to change the memory area reserved for
the VideoCore from 64 -> 76 MB, as this is the default
value on RPi4. Using other values would require configuration
of the first stage bootloader with 'config.txt' file.
Second fix is separating the disjunct memory areas
to separate nodes, as the generator Python scripts
in 'kernel/tools/' etc discarded the first area below
1GB limit if all areas were defined in the same node.
The effect of different variations can be observed
during kernel build in the generated
'kernel/gen_headers/plat/machine/devices_gen.h' header.
Third fix is adding the reserved memory area for the
VideoCore memory to avoid any collisions.

There are cases that reasonably require non-ASCII characters in the
source code, hence tools/bitfield_gen.py must be able to handle them
correctly. This commit makes sure the bitfield generator consistently

A tagged union can now optionally use multiple fields to indicate the
tag. These are called "sliced" tags in the code. The tag fields have to
be at the same position and width in each block of the tagged unions,
and all tag fields have to be within the same word.
When sliced tags are used, tag class masks cannot be used at the same
time for this tagged union.
In the `tagged_union` declaration, the values of such sliced tags
become tuples. For instance, if `x` and `y` are tag fields (declared in
blocks not shown here) with width 1 and 2, we can write:
tagged_union ex exType(x,y) {
tag ex1 (0,2)
tag ex2 (1,3)
}
