APM X-Gene SoC has a mailbox controller that provides
communication mechanism for X-Gene Arm64 cores to communicate
with X-Gene SoC's Cortex M3 (SLIMpro) processor.
X-Gene mailbox controller provides 8 mailbox channels, with
each channel has a dedicated interrupt line.
Changes since v5:
- Add more description into SlimPRO
mailbox data structure
Changes since v4:
- Rebase over v4.5-rc1
- Fix section mismatch warning during compiling
- Correctly print channel number when there is
no IRQ for that channel
- Change node name to mailbox at 10540000
- Correct the number of IRQs in documentation
Changes since v3:
- Rebase over v4.4
- Remove 'id' in slimpro_mbox_chan structure
- Remove functions that are only called once
and fold them into the other callers
- Remove void* pointer type cast
- Relax the number of mailbox IRQs condition
- Fix error and address comment in documentation
(xgene-slimpro-mailbox.txt)
Changes since v2:
- Rebase Feng's patch set over v4.3-rc5
- Remove uneccessary 'inline' in function definition
- Use module_platform_driver instead of subsys_initcall
- Minor coding stype clean up
Changes since v1:
- Add ACPI support
- Use defines for reg offset

The patch set is aimed for DT support. To support ACPI, additional
changes are required in mailbox common (core) code, which is not
available right now. And PCC seems to be the current mailbox
implementation approach for ACPI so I am not sure if Jassi has plan to
pull any non-PCC changes to support ACPI in mailbox core code or not.
But the patch should not cause the hang though. The hang is due to GIC
EOI feature. We have a new Tianocore firmware that correctly does GIC
fix-up to avoid the hang, but it may take a while before we release
it. In the mean time, you can comment out following likes of code in
function gic_v2_acpi_init of drivers/irqchip/irq-gic.c file to
continue booting in ACPI mode:
/*
* Disable split EOI/Deactivate if HYP is not available. ACPI
* guarantees that we'll always have a GICv2, so the CPU
* interface will always be the right size.
*/
/*
if (!is_hyp_mode_available())
static_key_slow_dec(&supports_deactivate);
*/

Hi Jassi,
Are you fine with this version of the patch?
