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
Have a plan to update Xen Wiki regarding this board.
