Arvind Ram Prakash ccb5616272 refactor(cpus): convert Neoverse N2 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: * 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 CTX_INCLUDE_AARCH32_REGS=0 \ HW_ASSISTED_COHERENCY=1 USE_COHERENT_MEM=0 \ BL33=./../tf-a-tests/build/fvp/debug/tftf.bin \ ERRATA_N2_2002655=1 ERRATA_N2_2025414=1 ERRATA_N2_2067956=1 ERRATA_N2_2189731=1 \ ERRATA_N2_2138956=1 ERRATA_N2_2138953=1 ERRATA_N2_2242415=1 ERRATA_N2_2138958=1 \ ERRATA_N2_2242400=1 ERRATA_N2_2280757=1 ERRATA_N2_2326639=1 ERRATA_N2_2376738=1 \ ERRATA_N2_2388450=1 ERRATA_N2_2743014=1 ERRATA_N2_2743089=1 ERRATA_DSU_2313941=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.
