set(CMAKE_BUILD_TYPE "Release") # "Release" or "Debug"
set(CHCORE_PLAT "raspi3")
set(CHCORE_ARCH "aarch64")
这里为了使得CMake支持调试应该将Release改成Debug。
产生的elf文件中，.text段含有调试信息。
`Disassembly of section .text:
ffffff000008c000 <start_kernel>:
* Code in bootloader specified only the primary
* cpu with MPIDR = 0 can be boot here. So we directly
* set the TPIDR_EL1 to 0, which represent the logical
* cpuid in the kernel
*/
mov x3, #0
ffffff000008c000: d2800003 mov x3, #0x0 // #0
msr TPIDR_EL1, x3
ffffff000008c004: d518d083 msr tpidr_el1, x3`
但是 .init不含有调试信息，不知道什么原因
