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overwritten the old (in the outdated config.mk).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)

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'.

Without any command under the .config target, config.mk will not be remade in

Add 'struct vpci_ops *ops' to 'struct vpci' so we have clearer structure:
- struct vpci: include struct vpci_ops pointing to different callback
functions for partition or sharing mode repsectively.
- struct pci_vdev: includes struct pci_vdev_ops to handle different vpci
functionalities:
hostbridge emulation
passthrough device BAR emulation
msi/msi-x remapping
This patch moves the code around but doesn't change the underlying logic
in terms of PCI spec handling. More detailed implementation:
- create new file partition_mode.c to house the implementation of partition mode
regarding the vpci layer.
- vpci.c: only keeps the abstract code which calls vpci->ops to functions
in partition_mode.c, and potentially to sharing_mode.c.
- the following functions are moved to partition_mode.c and renamed with
partition_mode prefix.
- vpci_init() -> partition_mode_vpci_init()
- vpci_cleanup() -> partition_mode_vpci_deinit()
- pci_cfg_io_write() -> partition_mode_cfgread()
- pci_cfg_io_read() -> partition_mode_cfgwrite()
