This reduces .bss size by 8 KiB, and should reduce overall memory usage
since most platforms will have significantly fewer than 512 entries in
this table. At the same time, it removes the fixed table size limit.
Since the table is only used within fdt_pmu.c, instead of updating the
extern declaration, make the table local to this file.

lib: utils: Add MPXY RPMI mailbox driver for System MSI service group2025-02-13T05:40:03+00:00Anup Patelapatel@ventanamicro.com2025-01-12T13:09:52+00:00urn:sha1:61abd975f22f96ac900c3482945bdc2f82f6a9f6
The supervisor software can directly receive most of the system MSIs
except P2A doorbell and MSIs preferred to be handled in M-mode.
Add MPXY RPMI mailbox client driver for the System MSI service group.

The service group ID assignment and some of the BASE services have
changes in the latest RPMI specification so let's update the RPMI
implementation accordingly.

attributes instead of hard coding them.

implement get_attribute() callback for the RPMI shared memory mailbox
controller.

lib: utils: Split the FDT MPXY RPMI mailbox client into two parts2025-02-13T05:40:03+00:00Anup Patelapatel@ventanamicro.com2025-01-11T09:08:34+00:00urn:sha1:d14340cb315195bd556ed89d5ca7a49335768ddc
Instead of having one common FDT MPXY RPMI mailbox client drivers
for various RPMI service groups, split this driver into two parts:
1) Common MPXY RPMI mailbox client library
2) MPXY driver for RPMI clock service group
The above split enables having a separate MPXY driver for each
RPMI clock service group and #1 (above) will allow code sharing
between various MPXY RPMI drivers.

lib: utils: Initialize miscellaneous drivers in one pass2025-02-12T16:09:25+00:00Samuel Hollandsamuel.holland@sifive.com2025-01-19T19:03:57+00:00urn:sha1:434add551c2a17cac3804ff0f587d31be03f070e
For driver subsystems that are not tightly integrated into the OpenSBI
init sequence, it is not important that the drivers are initialized in
any particular order. By putting all of these drivers in one array, they
can all be initialized with a single pass through the devicetree. This
saves about 10 ms of boot time on HiFive Unmatched.
