===========================
|
|
|
|
Trusted Firmware-A (TF-A) implements the EL3 firmware layer for QTI SC7180.
|
|
|
|
|
|
Boot Trace
|
|
-------------
|
|
|
|
Bootrom --> BL1/BL2 --> BL31 --> BL33 --> Linux kernel
|
|
|
|
BL1/2 and BL33 can currently be supplied from Coreboot + Depthcharge
|
|
|
|

Build Procedure
|
|
~~~~~~~~~~~~~~~
|
|
|
|
QTI SoC expects TF-A's BL31 to get integrated with other boot software
|
|
Coreboot, so only bl31.elf need to get build from the TF-A repository.
|
|
|
|
The build command looks like
|
|
|
|
make CROSS_COMPILE=aarch64-linux-gnu- PLAT=sc7180 COREBOOT=1
|
|
|
|
update value of CROSS_COMPILE argument with your cross-compilation toolchain.
|
|
|
|
Additional QTISECLIB_PATH=<path to qtiseclib> can be added in build command.
|
|
if QTISECLIB_PATH is not added in build command stub implementation of qtiseclib
|
|
is picked. qtiseclib with stub implementation doesn't boot device. This was
|
|
added to satisfy compilation.
|
|
|
|
QTISELIB for SC7180 is available at
