-Introduction
-------------
-
-A bootstrap can be used to change the model state, like the Exception
-Level (EL), before executing the UEFI binary.
-
-For the ARMv8 RTSM and FVP models this can be used to show/test the UEFI binary
-starting at different exception levels. The ARMv8 models start at EL3 by
-default.
-
-In the case of the Foundation model a bootstrap is required to jump to the
-UEFI binary as loaded in RAM. This is required as the Foundation model cannot
-load and execute UEFI binaries directly. The Foundation model can only load and
-execute ELF binaries.
-
-
-Build
------
-
-Build the bootstraps using a AArch64 GCC cross-compiler. By default the
-`Makefile` is configured to assume a GCC bare-metal toolchain:
-
- PATH=$PATH:<path/to/baremetal-tools/bin/> make clean
- PATH=$PATH:<path/to/baremetal-tools/bin/> make
-
-To build the bootstraps with a Linux GCC toolchain use the following
-commands:
-
- PATH=$PATH:<path/to/aarch64-linux-gnu-tools/bin/> make clean
- PATH=$PATH:<path/to/aarch64-linux-gnu-tools/bin/> CROSS_COMPILE=<gcc-prefix> make
-
-The `gcc-prefix` depends on the specific toolchain distribution used. It can be
-"aarch64-linux-gnu-" for example.
-
-This will result in four `axf` files:
-
-* uefi-bootstrap-el3 : The bootstrap jumps to the UEFI code in FLASH without
- changing anything.
-
-* uefi-bootstrap-el2 : Setup EL3 and switch the model to EL2 before jumping to the
- UEFI code in FLASH.
-
-* uefi-bootstrap-el1 : Setup EL3 and prepare to run at non-secure EL1. Switch to
- non-secure EL1 and run the UEFI code in FLASH.
-
-* uefi-bootstrap-el3-foundation : The bootstrap jumps to the UEFI code in RAM
- without changing anything. Only to be used with the
- Foundation model. The Foundation model does not have
- non-secure memory at address `0x0` and thus the UEFI image
- should be pre-loaded into non-secure RAM at address
- `0xA0000000`.
-
-
-Use on ARMv8 RTSM and FVP models
---------------------------------
-
-Add the '-a' option to the model start script and point to the required
-bootstrap:
-
- < ... model start script as described in top-level readme file ... >
- -a <path/to/bootstrap-binary-file>
-
-NOTE: The Foundation model bootstrap should not be used with these models.
-
-
-Use on ARMv8 Foundation model
------------------------------
-
-The Foundation model takes an option for an ELF file to be loaded as well as an
-option to load a binary data blob into RAM. This can be used to run UEFI in the
-following manner:
-
- <PATH_TO_INSTALLED_FOUNDATION_MODEL>/Foundation_v8 --cores=2 --visualization
- --image=uefi-bootstrap-el3-foundation.axf --nsdata=RTSM_VE_FOUNDATIONV8_EFI.fd@0xA0000000
-
-NOTE: The RTSM version of the bootstraps and UEFI image will not work as
- expected on the Foundation model. Foundation model specific versions
- should be used.
