Hello.
a question for the experts and a small wish/request.
is it possible to get the odroid hc2 up to same level of support in
the kernel as hc1?
my understanding is that they are basically the same thing but hc1
uses a 2.5 inch disk and hc2 uses 3.5 inch discs.
there is two parts to this i believe.
i'm using fedora 29 to test this and the first part is that uboot (i
think) doesn't recognize the hc2 properly so it tries to load the dtb
file exynos5422-odroidunknown.dtb
i can work around this by creating a symlink from
exynos5422-odroidhc1.dtb and get it to boot.
second part is ofcourse that there is no dtb file for hc2 so even if
uboot did pickup the right file it wound not exist.
using the hc1 dtb file with my hc2 appears to work fine.
From Linux kernel perspective Odroid HC2 doesn't differ from HC1, so it
simply should use HC1 dtb. Recently there have been u-boot patch for
adding HC2 detection, which also fixes 'unknown' dtb issue on HC2:

Best regards
Yes that would solve the problem and also confirms I'm doing the right thing by
using the hc1 dtb file.
Next problem is to see if i can figure out how to rebuild uboot and apply the
patch so i can test it.
I'll check the source and see what i can find.
Thanks.
