Related specifications are as following:
https://developer.arm.com/ip-products/processors/cortex-m
https://developer.arm.com/ip-products/processors/cortex-a
Bootstraped/Regtested for arm-none-linux-gnueabihf.
Please help to check.
Cheers
Dennis

The patch is ok. The ChangeLogshould list each new cpu entry as a
separate entity.
I've adjusted the ChangeLog to:
2019-08-23Â Dennis Zhang <dennis.zhang@arm.com>
   * config/arm/arm-cpus.in (cortex-m35p): New entry.
   (cortex-a76ae): Likewise.
   (cortex-a77): Likewise
   * config/arm/arm-tables.opt: Regenerate.
   * config/arm/arm-tune.md: Likewise.
   * doc/invoke.texi (ARM Options): Document cortex-m35p, cortx-a76ae,
   cortex-a77 CPU options.
and committed it to trunk for you with r274845.
Thanks for the patch!
