The 'boot' command is making use of a global
variable declared in the OS Loader but it might
not always be available if the Shell lib is
used with other code. This patch removes the
dependency on the global variable.
Also fixes a small issue with not providing a
value at the prompt; instead prompt the user
with a error message when no valid value has
been provided.

This patch allows OsLoader to handle all Boot Options without restarting.
Currently, OsLoader restarts to handle next Boot Option from the beginning.
This behavior does not preserve allocated memories from Payload heap,
so it makes hardware/software states hard to be maintained.

USB sub-system will have host controller scheduling frames on its

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
HOBs are finalized. The Linux boot parameters depend on HOBs to fill
correct information, such as frame buffer. With this patch, the boot
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.
