LS1043ARDB开发板bootloader单独编译过程

LS1043ARDB开发板环境bootloader版本包括以下几部分构成，分别编译，再组合成几个文件，下面列出整个bootloader的编译步骤：

总结一下就是：

1、先下载RCW源码文件，编译出PBL二进制文件。

2、再下载u-boot源码文件，编译出u-boot.bin文件。

3、[可选项]编译OP-TEE二进制文件。

4、继续编译TF-A二进制文件。(先编译出BL2二进制文件，再编译出FIP二进制文件)

1 . How to compile PBL binary from RCW source file

You need to compile the rcw_<boot_mode>.bin binary to build the bl2_<boot_mode>.pbl binary.

Clone the rcw repository and compile the PBL binary.

  1. $ git clone https://source.codeaurora.org/external/qoriq/qoriq-components/rcw
  2. $ cd rcw
  3. $ git checkout -b <new branch name> <LSDK tag>. For example, $ git checkout -b LSDK-19.06 LSDK-19.06
  4. $ cd <platform>
    If required, make changes to the rcw files.
  5. $ make

对于ls1043ardb开发板，编译特定RCW源码的命令总结如下：

2、u-boot版本下载与编译

How to compile U-Boot binary

先编译出u-boot.bin,再来编译fip.bin。
You need to compile the u-boot.bin binary to build the fip.bin binary.

Clone the u-boot repository and compile the U-Boot binary for TF-A.

  1. $ git clone https://source.codeaurora.org/external/qoriq/qoriq-components/u-boot.git
  2. $ cd u-boot
  3. $ git checkout -b <new branch name> LSDK-<LSDK version>.
    $ git checkout -b LSDK-19.06 LSDK-19.06
  4. $ export ARCH=arm64
  5. $ export CROSS_COMPILE=aarch64-linux-gnu-
  6. $ make distclean
  7. $ make <platform>_tfa_defconfig
    $ make ls1043ardb_tfa_defconfig
    A single defconfig is created for all the boot sources, <platform>_tfa_defconfig. For example, for
    LS1088ARDB, defconfig needs to be used is ls1088ardb_tfa_defconfig.
    NOTE
  8. $ make
    If the make command shows the error "*** Your GCC is older than 6.0 and is not supported" ,
    ensure that you are using Ubuntu 18.04 64-bit version for building LSDK 19.06 U-Boot binary.

对于ls1043ardb开发板，编译特定u-boot命令总结如下：

git clone https://source.codeaurora.org/external/qoriq/qoriq-components/u-boot.git
cd u-boot
git checkout -b LSDK-19.06 LSDK-19.06
export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-
make distclean
make ls1043ardb_tfa_defconfig
make

3、[Optional] How to compile OP-TEE binary

You need to compile the tee.bin binary to build fip.bin with OP-TEE. However, OP-TEE is optional, you can skip the procedure to compile OP-TEE if you want to build the FIP binary without OP-TEE.
Clone the optee_os repository and build the OP-TEE binary.

  1. $ git clone https://source.codeaurora.org/external/qoriq/qoriq-components/optee_os
  2. $ cd optee_os
  3. $ git checkout -b <new branch name> LSDK-<LSDK version>. For example, $ git checkout -b LSDK-19.06
    LSDK-19.06
  4. $ export ARCH=arm
  5. $ export CROSS_COMPILE64=aarch64-linux-gnu-
  6. $ make CFG_ARM64_core=y PLATFORM=ls-<platform>. For example, $ make CFG_ARM64_core=y PLATFORM=lsls1088ardb
  7. $ aarch64-linux-gnu-objcopy -v -O binary out/arm-plat-ls/core/tee.elf out/arm-plat-ls/core/tee.bin
    The compiled OP-TEE image, tee.bin, is available at optee_os/out/arm-plat-ls/core/.

对于ls1043ardb开发板，编译特定OP-TEE二进制的命令总结如下：

git clone https://source.codeaurora.org/external/qoriq/qoriq-components/optee_os
cd optee_os/
git checkout -b LSDK-19.06 LSDK-19.06
export ARCH=arm
export CROSS_COMPILE64=aarch64-linux-gnu-
make CFG_ARM64_core=y PLATFORM=ls-ls1043ardb
aarch64-linux-gnu-objcopy -v -O binary out/arm-plat-ls/core/tee.elf out/arm-plat-ls/core/tee.bin
具体如下：

4、How to compile TF-A binaries

Clone the atf repository and compile the TF-A binaries, bl2_<boot_mode>.pbl and fip.bin.

  1. $ git clone https://source.codeaurora.org/external/qoriq/qoriq-components/atf
  2. $ cd atf
  3. $ git checkout -b <new branch name> LSDK-<LSDK version>. For example, $ git checkout -b LSDK-19.06 LSDK-19.06
  4. $ export ARCH=arm64
  5. $ export CROSS_COMPILE=aarch64-linux-gnu-
    Follow the steps mentioned in How to compile BL2 binary on page 127 (bl2_<boot_mode>.pbl) and How to compile FIP binary
    on page 128 (fip.bin) to compile both TF-A binaries.

对于ls1043ardb开发板，编译特定TF-A二进制的命令总结如下：

git clone https://source.codeaurora.org/external/qoriq/qoriq-components/atf
cd atf
git checkout -b LSDK-19.06 LSDK-19.06
export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-
4.1 How to compile BL2 binary

To build BL2 binary with OPTEE, run this command:
$ make PLAT=<platform> bl2 SPD=opteed BOOT_MODE=<boot_mode> BL32=<optee_binary> pbl
RCW=<path_to_rcw_binary>/<rcw_binary_for_specific_boot_mode>
The compiled BL2 binaries, bl2.bin and bl2_<boot_mode>.pbl are available at atf/build/<platform>/release/. For any
update in the BL2 source code or RCW binary, the bl2_<boot_mode>.pbl binary needs to be recompiled.

To compile the BL2 binary without OPTEE:
make PLAT=<platform> bl2 BOOT_MODE=<boot_mode> pbl RCW=<path_to_rcw_binary>/
<rcw_binary_for_specific_boot_mode>

对于ls1043ardb开发板，编译特定BL2二进制的命令总结如下：

make PLAT=ls1043ardb bl2 SPD=opteed BOOT_MODE=nor BL32=/home/imhqq/share/bootloader/optee_os/out/arm-plat-ls/core/tee.bin pbl RCW=/home/imhqq/share/bootloader/rcw/ls1043ardb/RR_FQPP_1455/rcw_1600.bin
4.2 How to compile FIP binary

To build FIP binary with OPTEE and without trusted board boot, run this command:
$ make PLAT=<platform> fip BL33=<path_to_u-boot_binary>/u-boot.bin SPD=opteed
BL32=<path_to_optee_binary>/tee.bin
The compiled BL31 and FIP binaries, bl31.bin, fip.bin, are available at atf/build/<platform>/release/. For any update
in the BL31, BL32, or BL33 binaries, the fip.bin binary needs to be recompiled.

To compile the FIP binary without OPTEE and without trusted board boot:
make PLAT=<platform> fip BL33=<path_to_u-boot_binary>/u-boot.bin
NOTE
To compile the FIP binary with trusted board boot, refer the read me at <tfa_repo>/plat/nxp/
README.TRUSTED_BOOT.

对于ls1043ardb开发板，编译特定FIP二进制的命令总结如下：

make PLAT=ls1043ardb fip BL33=/home/imhqq/share/bootloader/u-boot/u-boot.bin SPD=opteed BL32=/home/imhqq/share/bootloader/optee_os/out/arm-plat-ls/core/tee.bin
编译不带OPTEE及不带可信单板BOOT的FIP二进制文件：

To compile the FIP binary without OPTEE and without trusted board boot:
make PLAT=<platform> fip BL33=<path_to_u-boot_binary>/u-boot.bin

对于ls1043ardb开发板，编译不带OPTEE及不带可信单板BOOT的FIP二进制文件总结如下：

make PLAT=ls1043ardb fip BL33=/home/imhqq/share/bootloader/u-boot

NOTE
To compile the FIP binary with trusted board boot, refer the read me at <tfa_repo>/plat/nxp/
README.TRUSTED_BOOT.

最终编译出的ls1043ardb单板的bootloader文件在下面的路径：

/home/imhqq/share/bootloader/atf/build/ls1043ardb/release

root@ubuntu:/home/imhqq/share/bootloader/atf/build/ls1043ardb/release# ls
bl2  bl2.bin  bl2_nor.pbl  bl31  bl31.bin  fip.bin
