flash-image.bin build for MACCHIATObin Single Shot, on Arch Linux x86_64, fails in include/lib/mmio.h.
To re-produce:
- pacman -Sy aarch64-linux-gnu-gcc - currently it's aarch64-linux-gnu-gcc (GCC) 12.2.0.
- export CROSS_COMPILE=aarch64-linux-gnu-
- git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
- Clone the binaries-marvell and mv-ddr-marvell Git repos alongside the trusted-firmware-a, and check out revisions as recommeded in TF-A build instructions for Armada80x0.
- Build u-boot.bin:
- git clone https://source.denx.de/u-boot/u-boot.git alongside the binaries-marvell and mv-ddr-marvell repos.
- cd u-boot
- git checkout v2023.01 - the latest release.
- make mvebu_mcbin-88f8040_defconfig
- Change CONFIG_DEFAULT_DEVICE_TREE to "armada-8040-mcbin-singleshot" (inspired by this SolidRun doc).
- Add arch/arm/dts/armada-8040-mcbin-singleshot.dts. Can be obtained from the latest Marvell kernel sources.
- make, built fine, cool.
- Trying to build TF-A:
- cd ../trusted-firmware-a/
- git checkout v2.8.0 - the latest release, as per changelog.
- make PLAT=a80x0_mcbin MV_DDR_PATH=../mv-ddr-marvell SCP_BL2=../binaries-marvell/mrvl_scp_bl2.img BL33=../u-boot/u-boot.bin mrvl_flash - error:
