[libcpu][aarch64] Replace x8 with a callee-saved register

Fixup the boot EL check

2025-07-07T02:58:52Z

The boot EL will save in x0, when current EL is EL3, kernel will jump to the EL2 after EL3. But the x0 value is **3**, The init for EL2 will not work. To fix it: the EL3 should jump to the EL2 init branch with not check, and when SoC boot in EL2, kernel will jump to the EL2 test branch.

[arm64] add hw thread self (#8942)

2024-05-28T06:27:55Z

* [libcpu] arm64: Add hardware thread_self support This patch introduces hardware-based thread self-identification for the AArch64 architecture. It optimizes thread management by using hardware registers to store and access the current thread's pointer, reducing overhead and improving overall performance. Changes include: - Added `ARCH_USING_HW_THREAD_SELF` configuration option. - Modified `rtdef.h`, `rtsched.h` to conditionally include `critical_switch_flag` based on the new config. - Updated context management in `context_gcc.S`, `cpuport.h` to support hardware-based thread self. - Enhanced `scheduler_mp.c` and `thread.c` to leverage the new hardware thread self feature. These modifications ensure better scheduling and thread handling, particularly in multi-core environments, by minimizing the software overhead associated with thread management.
