# Build system notes.
|
#
|
# The EDK2 build system is rather unique, so here are a few useful notes.
|
#
|
# First, builds rely heavily on Git submodules to fetch various dependencies
|
# into specific directory structures. It might be possible to work around this
|
# and rely on Buildroot's infrastructure, but using Git submodules greatly
|
# simplifies this already complicated build system.
|
#
|
# Second, the build system is spread across various commands and stages.
|
# Therefore, all build variables needs to be exported to be available
|
# accordingly. The first stage will build $(@D)/BaseTools which contains
|
# various tools and scripts for the host.
|
#
|
# Third, where applicable, the dependency direction between EDK2 and
|
# ARM Trusted Firmware (ATF) will go in different direction for different
|
# platforms. Most commonly, ATF will depend on EDK2 via the BL33 payload.
|
# But for some platforms (e.g. QEMU SBSA or DeveloperBox) EDK2 will package
|
# the ATF images within its own build system. In such cases, intermediary
|
# "EDK2 packages" will be built in $(EDK2_BUILD_PACKAGES) in order for EDK2
|
# to be able to use them in subsequent build stages.
|
#
