Hello Yakir,
Sorry for the delay but I was on holidays.

Yes, as I mentioned in the blog, there are many options. In fact I also boot from
a uSD instead of the eMMC since is easier for me to flash from the host machine
and chain load a non-verified u-boot so I can boot non signed kernels.
But thought that the most common use case would be to install it in the KERN-C and
ROOT-C partitions in the eMMC. Anyways, I'm glad that you got it working.

Interesting, I knew about pstore but I never used it with the Exynos Chromebooks.

Are you using mainline? There isn't a "ramoops" compatible string documented
in the upstream DT bindings, platform_match() would match by driver name as
a fallback but I don't see code in fs/pstore/ram.c that parses the properties
in your device node. I wonder how this works for you or did I missunderstand?
