lib: utils/fdt: Allocate fdt_pmu_evt_select on the heap2025-02-19T12:55:17+00:00Samuel Hollandsamuel.holland@sifive.com2025-02-13T22:48:39+00:00urn:sha1:a2c172f526b52eb428d9077fab8cd8690c7e2f19
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: sbi: Fix non-root domain startup2025-02-19T11:41:39+00:00Anup Patelapatel@ventanamicro.com2025-02-11T15:36:23+00:00urn:sha1:1f64fef919fc5739df6c3395a9abd256dc88cb24
Currently, the sbi_sse_init() in cold boot path is called after
sbi_domain_finalize() so boot HART of non-root domains will start
before SSE cold boot init which can cause warm boot of such HARTs
to crash in sbi_sse_init().
To address the above issue, factor-out the non-root domain startup
from sbi_domain_finalize() function as a separate sbi_domain_startup()
function which can be called after sbi_sse_init() in cold boot path.

The latest SBI 3.0 spec defines a new sbi_mpxy_get_shmem_size()
function and simplifies sbi_mpxy_set_shmem() function so update
the MPXY framework and SBI extension accordingly.

implementation accordingly.
