Hi, all

gentle reminder...


This is in my queue of patches to review. Also, as we are in freeze, I 
tend to prioritize patches for 4.12.


I will try to have a look next week.



I understand. Thank you.




Cheers,

Hi, all.



Hi, all

gentle reminder...




The purpose of this patch series is to add required support to be able to run
Xen on Renesas Stout board [1] which uses SCIFA compatible UART as a console
interface.

Actually Xen already has support for SCIF compatible UARTs which are used on
Renesas Lager (R-Car Gen2), Salvator-X, H3ULCB/M3ULCB (R-Car Gen3) and other
development boards. So this patch series extends existing support to be able
to handle both interfaces.

Current patch series is based on the following commit 
3389a8dc8c5753a3c84744923cd0193395e3f2a9
and tested on Stout (ARM32) and H3ULCB (ARM64) boards.

You can find current patch series here:
repo: https://github.com/otyshchenko1/xen.git branch: stout_upstream

You can find previous discussion here:
https://www.mail-archive.com/xen-devel@lists.xenproject.org/msg21058.html

Please note, that current patch series doesn’t have the following patches:
- xen/arm: drivers: scif: Remove unused #define-s (already upstreamed)
- xen/arm: Reuse R-Car Gen2 platform code for Stout board (was dropped)
but has new one:
- xen/arm: Clarify usage of earlyprintk for Lager board

--

In order to run Xen on Stout board you need "PSCI-enabled" U-Boot (not 
upsteamed yet).
You can find corresponding patches for U-Boot here:
http://u-boot.10912.n7.nabble.com/PATCH-0-3-PSCI-support-for-r8a7790-SoC-Lager-Stout-boards-td357352.html
