Everyone:
Picking up where Sascha left off, this is the next version of the
patchset that adds support for i.MX8MQ EVK board.
Changes since [v1]:
- The patchset now allows building 1st stage bootloader that can be
progammed on SD card and booted standalone
Currently out of scope of this patch (not tested or documented, will
be coming in a follow up series):
- Integration of ARM Trusted Firmware
- Booting Linux kernel
Current assumptions (all subject to change, but listed below to be
explicit):
- DDR initialization code is auto-generated by i.MX8M DDR Tool and
used as close to as-is as possible.
- Barebox-to-generated code (above) "adapter" header file is
exptected to be board specific to be able to handle changes to
what new versions of i.MX8M DDR Tool produces
- Currently it is assumed that DDR PHY fimware is board specific too
and is expected to be placed into board folder as a pre-requisite
(can't be distributed with Barebox due to a restrictive EULA)
Feedback is wellcome!
Thanks,
Andrey Smirnov
