This patch splitted LoadBzImage() into two functions. One is just
for kernel loading. The other one UpdateLinuxBootParams() is for
Linux boot parameter updates. It is required to do so because when
kernel loading in Stage2 is enabled the loading occurs before all

parameters can be updated at the very end.

OsLoader has the capability to boot a Linux kernel. However, to support
LinuxBoot type of payload, it is required to load kernel in Stage2. This
patch abstracts the standard Linux loading logic into common LinuxLib
class so that it can be linked in Stage2 or Payload such as OsLoader.
A new PcdLinuxPayloadEnabled is introduced to control if this feature
should be enabled or not.
To boot a Linux kernel from Stage2, it is required to put the command
line file and kernel image into the EPAYLOAD container during the build.
And the PayloadId CFGDATA needs to be set to 'LINX'.
For example:
python BuildLoader.py build qemu
-p OsLoader.efi::Lz4;vmlinuz:LINX:Dummy;cmdline.txt:CMDL:Dummy
vmlinuz and cmdkube.txt need to be copied to PayloadPkg/PayloadBins
folder. If kernel size cannot fit into EPAYLOAD, EPAYLOAD_SIZE in
BoardConfig.py needs to be adjusted accordingly.
Signed-off-by: Maurice Ma <maurice.ma@intel.com>
The current implementation used a huge array to represent boot options in
a single CFGDATA tag. With this approach, when a different board needs
to modify a single field, the whole array needs to be duplicated in the
CFGDATA. It is not efficient. A better approach is to break the options
into individual boot option CFGDATA tag. It will reduce the overall CFGDATA
in general. This patch implemented this mechanism. A library interface
FillBootOptionListFromCfgData() is provided to convert the CFGDATA into
the required OS_BOOT_OPTION_LIST.

Following modifications are made for existing firmware update flow
1) Gather and validate capsule image

During each reboot until the end of firmware update, stored signature
will be compared against the capsule image signature to make sure
capsule image is not modified until the end of firmware update.
4) Process Capsule image to gather firmware images
5) Each Firmware image information will be stored in reserved region
using FW_UPDATE_COMP_STATUS. Update pending will be marked to
update pending state indicating that this image is not processed.
6) Firmware update will use the reserved region comp structures starting
with the first image with update pending state, update the comp update
pending field to processing and applies the image. After the update, pending
field will be updated to Done and updates the status of the update in the
component structure and moves on to next image found.
