Subject: [PATCH] verdin-imx8mm: add initial setup
Add initial verdin.mk for the minimal setup for OP-TEE testing.
This setup uses latest mainline TF-A (v.2.2) / U-Boot (v2020.03) /
Linux (5.6-rc).
Verdin i.MX8M Mini boot sequence:
BootROM -> SPL -> TF-A (BL31) -> OP-TEE (BL32)
|
-> U-Boot (BL33) -> Linux
TF-A(bl31.bin), U-Boot proper and OP-TEE (tee.bin) are packed in FIT image,
which is parsed by SPL.
Deploying:
1. Flasing flash.bin (IMX ready-to-boot image):
> dhcp && tftpboot ${loadaddr} flash.bin
> setexpr blkcnt ${filesize} + 0x1ff
> setexpr blkcnt ${blkcnt} / 0x200
> mmc dev 0 1 && mmc write ${loadaddr} 0x2 ${blkcnt}
2. Boot Linux kernel via TFTP/NFS:
-> setenv serverip <ip_of_your_server>
-> setenv nfsroot /path/to/nfs/root
-> setenv fdt_file fsl-imx8mm-verdin-dev.dtb
-> setenv bootargs "console=${console},${baudrate} root=/dev/nfs \
ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp"
-> tftp ${loadaddr} ${image}; tftp ${fdt_addr} ${fdt_file};
-> booti ${loadaddr} - ${fdt_addr}
Test results:
+-----------------------------------------------------
24600 subtests of which 0 failed
98 test cases of which 0 failed
0 test cases were skipped
TEE test application done!
