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
