Everyone:
This is part II of i.MX8MQ EVK board support patches. This time this
is bits and pieces that were necessary in order to allow booting
vendor Linux kernel availible here (tag: rel_imx_4.9.51_8mq_ga):
https://source.codeaurora.org/external/imx/linux-imx
Sources for ATF were taken from here (tag: rel_imx_4.9.51_8mq_ga):
https://source.codeaurora.org/external/imx/imx-atf
This patchest is also availible at:
https://github.com/ndreys/barebox/tree/imx8m-support-part-II-v2
Feedback is welcome!
Changes since [v1]:
- Opcode patching is replaced with placing barebox image at the
right spot
- ATF loading code is converted into a function (was a macro
originally)
- It is now up to the user to check current EL when calling
imx8mq_atf_load_bl31()
- Other various small change as per Sascha's feedback
[v1] http://lists.infradead.org/pipermail/barebox/2018-June/033922.html
Thanks,
Andrey Smirnov
