Tw ce387084ed hv: remove CONFIG_PLATFORM_[SBL|UEFI] and UEFI_STUB
ACRN now has unified the way to handle SBL and UEFI.
so just remove corresponding macros in Kconfig.
BTW, default configuration in Kconfig is for UEFI boards.

Tw 59c2b33a90 Makefile: separate PLATFORM into BOARD+FIRMWARE
Combination of BOARD and FIRMWARE is a more precious definition.
And we decide PLATFORM_XXX based on FIRMWARE, remove relative one in
board config.

We reserve PLATFORM for backward compatibility.

Junjie Mao 5f6a10f1e1 kconfig: use defconfig instead of default values in silentoldconfig
Currently silentoldconfig uses the default values in Kconfig when .config does
not exist or is for a different platform from the one specified in command line
options. This makes it impossible to leverage defconfigs when a simple 'make' is
invoked to build the hypervisor, as 'make' calls oldconfig instead of defconfig
for creating a configuration file.

With DEFCONFIG_LIST in Kconfig, now silentoldconfig is also able to know which
defconfig is appropriate given the specified board. This patch changes the
behavior of oldsilentconfig as follows.

    1. When an old .config for the given board exists, the script updates the
       .config per configurations specified from the command line. Instead of
       manually resetting all symbols, the script now relies on Kconfiglib's
       internal logic to automatically update invisible symbols after symbol
       value changes.

    2. When an old .config does not exist or is not for the specified board, the
       defconfig for that board is used as base line and further tweaked per
       configurations from the command line.

v3 -> v4:

* Rephrase comments in silentoldconfig.py.

v2 -> v3:

* Keep backward compatibility of silentoldconfig.py since vmcfg also uses the
  script.

v1 -> v2:

* Include .config when it is edited manually so that new configurations
  overwritten the old (in the outdated config.mk).

* Compare the board in .config with the one in the defconfig instead of what is
  specified in the environment variable BOARD, as defconfig and BOARD may use
  different names (e.g. aliases or different cases)

Junjie Mao b9d54f4ab3 kconfig: support board-specific defconfig
The current defconfigs are BIOS-specific which makes it difficult to maintain
multiple defconfigs for boards running the same BIOS.

This patch re-organizes the defconfigs to be board-specific. A command line
option BOARD is introduced to specify a board on which the current build targets
at. The original PLATFORM is kept for backward compatibility which redirects to
apl-mrb and nuc6cayh for sbl and uefi, respectively.

The getting started guide is also updated accordingly.

v1 -> v2:

* Rewrite 'up2' to 'UP2'.

Junjie Mao 8bde372c32 kconfig: enforce remaking config.mk after oldconfig changes .config
Without any command under the .config target, config.mk will not be remade in
the same execution of make after oldconfig changes .config. This can result to
inconsistency between .config and the built image right after .config is
changed.

Junjie Mao c7907a823c kconfig: a faster way to check the availability of python3 package
It is faster to check the existance of a certain library by trying importing

Junjie Mao 8009cccb52 HV: make: manage debug/release build in kconfig
This patch introduces a configuration symbol RELEASE for managing debug/release
build in a similar way to how we manage PLATFORM.

Note:

1. 'make defconfig RELEASE=1' will still use the CONFIG_RELEASE defined in the
   default configuration. The 'RELEASE=1' option has no effect in this case.

2. 'make RELEASE=1' is backward-compatible and enforces a release version to be
   built.

v1 -> v2:

    * Pass RELEASE instead of CONFIG_RELEASE to silentoldconfig.py to avoid
      unintended overriding of the value.

Junjie Mao c4493cc1f8 HV: make: skip duplicated PLATFORM= on command line
Since .config has PLATFORM now, it is expected that the PLATFORM= command line
option is no longer necessary as long as a proper .config exists.

This patch implements this expectation. Now the platform to be selected is
determined by the following steps.

    1. If PLATFORM= is provided on the command line, the specified value is
       used.
    2. If there is no PLATFORM= on the command line and PLATFORM is defined in
       config.mk, its value is used.
    3. If neither PLATFORM= on the command line nor config.mk is available, a
       predefined default value is used.

v1 -> v2:

    * 'make oldconfig' should not pass CONFIG_xxx to the script since config.mk
      can be out-dated.
    * Change the default value of PLATFORM to SBL for backward compatibility of
      'make all'.

This patch enables 'make menuconfig' leveraging the menuconfig.py in kconfiglib,
which shows a TUI for modifying the current configurations.

Menuconfig.py is python3 only, and thus the existence of 'python3' instead of
'python' is checked and python3 is used to run all the scripts.

Junjie Mao 216f4e78a8 HV: make: append dependency checking targets to a given variable
The current implementation of the check_dep_* macros always append the
prerequisite checking target to BUILD_DEPS, but there are some cases when some
prerequisites are only necessary for some specific targets instead of general
builds.

This patch adds a second parameter to the check_dep_* macros specifying which
variable the generated target should be appended to.

Junjie Mao 063557a263 HV: make: drop double quotes in config.mk
Makefile takes all double quotes in variable definitions literally. Thus with
the following definition:

    FOO := "a"

expanding FOO in a file path results the following (which is invalid):

    SRC += a/b/${FOO}.c  --> SRC += a/b/"a".c

To avoid such issues, this patch drops the double quotes at the beginning and
end of the definition of symbols with string type.

Junjie Mao f9bb2024cc HV: make: introduce targets for generating configs
This patch implements the following targets as an includable .mk to the make
system of the hypervisor.

    make defconfig PLATFORM=xx:
        force (re)generating the default configuration for xx

    make oldconfig PLATFORM=xx:
        generate a configuration for platform xx based on .config if available

    make minimalconfig
        save a minimized .config to defconfig

The default target (make all) will generate a default configuration if no
.config is available.

The values defined in .config are available in the toplevel Makefile after
kconfig/kconfig.mk is included.

v4 -> v5:

    * Add minimalconfig for generating default configs.

v3 -> v4:

    * No changes.

v2 -> v3:

    * "make defconfig" now correctly overwrite an existing .config.
    * Add short descriptions on where each target is supposed to be used.

v1 -> v2:

    * Add proper dependency checks in the Makefile of hypervisor.
