Arvind Ram Prakash 7f798aaa3e refactor(cpus): convert Neoverse V1 to framework ... This involves replacing: * the reset_func with the standard cpu_reset_func_{start,end} to apply errata automatically * the <cpu>_errata_report with the errata_report_shim to report errata automatically ...and for each erratum: * the prologue with the workaround_<type>_start to do the checks and framework registration automatically * the epilogue with the workaround_<type>_end * the checker function with the check_erratum_<type> to make it more descriptive It is important to note that the errata workaround sequences remain unchanged and preserve their git blame. Testing was conducted by: * Building for release with all errata flags enabled and running script in change 19136 to compare output of objdump for each errata. Only able to verify the check functions this way, rest had to manually verified * Manual comparison of disassembly of converted functions with non- converted functions aarch64-none-elf-objdump -D <trusted-firmware-a with conversion>/build/fvp/release/bl31/bl31.elf vs aarch64-none-elf-objdump -D <trusted-firmware-a clean repo>/build/fvp/release/bl31/bl31.elf * Build for release with all errata flags enabled and run default tftf tests CROSS_COMPILE=aarch64-none-elf- make PLAT=fvp DEBUG=0 \ CTX_INCLUDE_AARCH32_REGS=0 HW_ASSISTED_COHERENCY=1 USE_COHERENT_MEM=0 \ BL33=./../tf-a-tests/build/fvp/release/tftf.bin \ ERRATA_V1_1618635=1 ERRATA_V1_1774420=1 ERRATA_V1_1791573=1 \ ERRATA_V1_1852267=1 ERRATA_V1_1925756=1 ERRATA_V1_1940577=1 \ ERRATA_V1_1966096=1 ERRATA_V1_2108267=1 ERRATA_V1_2139242=1 \ ERRATA_V1_2216392=1 ERRATA_V1_2294912=1 ERRATA_V1_2372203=1 \ ERRATA_V1_2743093=1 ERRATA_V1_2743233=1 ERRATA_V1_2779461=1 \ WORKAROUND_CVE_2022_23960=1 ERRATA_ABI_SUPPORT=1 all fip * Build for debug with all errata enabled and step through ArmDS at reset to ensure all functions are entered.
