Hi Folks,

A quick note that I'm poking at a test kernel with
ACPI_INITRD_TABLE_OVERRIDE support. I don't condone this for production
kernels, but for testing fixes to DSDT's and SSDT's it can be very
useful to insert updated tables into the initrd (this is commonplace on
x86 during development). If someone already poked at this, let me know
if you plan to post something upstream, etc.

I think Naresh will work that, we discussed that on IRC,

+Cc Naresh

by the way, if you want to replace the dsdt/ssdt only to debug
the system, you can use dsdt override feature, please see
Documentation/acpi/dsdt-override.txt, but it needs recompile
the kernel. I tested that on ARM64 and it works.

Yes, I am working on it. This feature can't be used on the production systems. But certainly it will be useful for debugging purpose. It is required to re-compile the kernel. I will post the patches ASAP.

Thanks
Hanjun
