[PATCH v2 0/9] Some improvements on boot sequence

[Xiang W]

This series of patches are some multi-HARTs related optimizations, 
allowing non-coldboot HART to perform more initialization before 
entering HSM wait, and fixing some multi-HARTs expansion related 
issues.

V2 Change:
- Remove unused function sbi_wait_for_non_boot_harts and 
  sbi_signal_non_boot_harts_done
- Keep init_coldboot and init_warm_startup as suggested by anup

Xiang W (9):
  lib: sbi: Implement synchronisation and wait between multiple HARTs
  lib: sbi: Remove wait_for_coldboot and wake_coldboot_harts
  lib: sbi: Add wait operations in some initialization functions
  lib/utils: Make fdt_parse_isa_extensions reentrant
  lib: sbi: Initialize as much as possible on non-coldboot HART
  lib: sbi: Ensure that all Harts complete sbi_hart_init
  lib/utils: Fix Zicntr detection in fdt_cpu_fixup
  lib: sbi: Fix dtbr initialization
  lib: sbi: Add sbi_double_trap_init to init_warm_startup
