      verdin-imx8mm: add initial setup · 3bf187d6
      Igor Opaniuk authored 
      
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!

      hikey960: fix EDK2 build with GCC 9.x · 1e8d0b5a

      The current EDK2 code fails to build with GCC 9.x:

 make[3]: *** [../Makefiles/footer.makefile:27: GenVtf.o] Error 1

This error was found with Ubuntu 19.10 (comes with GCC 9.2.1).

The HiKey960 EDK2 repository [1] has not received any update in the
past year, I am not sure it is still maintained. There is apparently
some support for HiKey960 in the upstream EDK2 repositories [2] and
[3], but I could not get my board to boot with upstream code.

So, a quick fix seems in order.

      common.mk: buildroot: append BR2_ variables to config automatically · 7fbd6ce2
      Jerome Forissier authored 
      
To set additional BR2_ variables, the user currently needs to edit
common.mk and modify the buildroot recipe. It is inconvenient,
especially since a line with a cumbersome syntax has to be added. One
would expect to be able to specify the desired value on the make
command line or directly in the Makefile. For instance, to enable
debug mode: make BR2_ENABLE_DEBUG=y.

This patch updates the buildroot recipe to enumerate all the Makefile
variables that start with BR2_, and each such variable is automatically
added to ../out-br/extra.conf.

As a result the existing BR2_ variables can be set in a simpler way.

Tested on QEMU, results in the same ../out-br/.config except for the
line order.
