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 clean
repo>/build/fvp/release/bl31/bl31.elf
* Build for release with all errata flags enabled and compare
the disassembly of converted functions with non-converted
functions.
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_A73_852427=1 \

WORKAROUND_CVE_2017_5715=1 \
WORKAROUND_CVE_2018_3639=1 \
WORKAROUND_CVE_2022_23960=1
* Build for debug with all errata enabled and step through ArmDS
at reset to ensure all functions are entered.
