lib: Allow custom CSRs in csr_read_num() and csr_write_num()

2025-10-21T14:04:09Z

Some of the platforms use platform specific CSR access functions for configuring implementation specific CSRs (such as PMA registers). Extend the common csr_read_num() and csr_write_num() to allow custom CSRs so that platform specific CSR access functions are not needed.

generic: mips: support harts to boot from mips_warm_boot

2025-08-28T05:30:16Z

We program reset base for harts (other than hart 0) to boot at mips_warm_boot that jumps to _start_warm. This helps to skip some code sequence to speed up.

lib: sbi_platform: Add platform specific pmp_set() and pmp_disable()

2025-06-17T04:04:01Z

Allow platforms to implement platform specific PMP setup and PMP disable functions which are called before actual PMP CSRs are configured. Also, implement pmp_set() and pmp_disable() for MIPS P8700.
