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'.

Junjie Mao 6df3ac0038 HV: make: add menuconfig
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 eecac5ab88 HV: make: force updating .config and config.mk
Before checking any given target, make has an additional phase to check if any
included makefile should be updated. This patch enforces running oldconfig in
this phase to update .config and config.mk (if necessary). This ensures that
make gets the correct configurations when executing the given target.

Junjie Mao c849bff850 HV: config: adapt to the generated config.h
This patch drops "#include <bsp_cfg.h>" and include the generated config.h in
CFLAGS for the configuration data.

Also make sure that all configuration data have the 'CONFIG_' prefix.

v4 -> v5:

    * No changes.

v3 -> v4:

    * Add '-include config.h' to hypervisor/bsp/uefi/efi/Makefile.
    * Update comments mentioning bsp_cfg.h.

v2 -> v3:

    * Include config.h on the command line instead of in any header or source to
      avoid including config.h multiple times.
    * Add config.h as an additional dependency for source compilation.

v1 -> v2:

    * No changes.

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.
