> This patch series using ZynqMP firmware driver to provide a interface to

> There are two new wiring:

>  - mailbox driver in case of SPL
>  - SMC in case of full U-Boot
> 2. Using the same patch for loading PMUFW configuration object

> The whole series is based on several patches I have sent already that's why
> I am providing a branch which also contains this series.

> Changes in v2:
> - Check error separately - Reported by Luca
> - Align ret handling
> - Also handle error from mbox_recv/mbox_send
> - Move pm_api_id higher - Reported by Luca
> - Fix macros for header protection
> - pass rex_maxlen to ipi_req - reported by Luca

> Ibai Erkiaga (10):
>   mailbox: check ops prior calling
>   mailbox: allow subnode for mbox regs
>   mailbox: zynqmp: ipi mailbox driver
>   firmware: zynqmp: Add zynqmp-power support

Applied all. Only in this patch I have fixed dependencies to be
selected via ARCH fragment.
Because IPI driver hasn't been adopted by Versal to be able to select
IPI directly.
