![]() 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 and checking 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 <TF-A with conversion>/build/../release/bl31/bl31.elf vs aarch64-none-elf-objdump -D <TF-A with clean repo>/build/fvp/release/bl31/bl31.elf * Build for release with all errata flags enabled and ensure the changes were identical. CROSS_COMPILE=aarch64-none-elf- make PLAT=fvp \ DEBUG=0 HW_ASSISTED_COHERENCY=0 \ BL33=<tf-a-tests>/build/fvp/debug/tftf.bin \ all fip ERRATA_A35_855472=1 * Build for debug with all errata enabled and step through ArmDS at reset to ensure all functions are entered.
