From: Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx> Hi, all. 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 1c6504163595d45e47a01750318c2b7b50541cbe 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_upstream3 You can find previous discussions here: [V1] https://www.mail-archive.com/xen-devel@xxxxxxxxxxxxxxxxxxxx/msg21058.html [V2] https://www.mail-archive.com/xen-devel@xxxxxxxxxxxxxxxxxxxx/msg37518.html [V3] https://www.mail-archive.com/xen-devel@xxxxxxxxxxxxxxxxxxxx/msg42493.html [V4] https://www.mail-archive.com/xen-devel@xxxxxxxxxxxxxxxxxxxx/msg43332.html ---------- 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. ---------- Please note, that first two patches already have Julien's A-b, and the following patch "[PATCH V4 1/5] xen/arm: Clarify usage of earlyprintk for Lager board" was removed from this series (as handled separately).
