Currently, there are few chip specific erratas present in nvgpu code.
For better traceability of the erratas and corresponding fixes,
introduce flags to indicate existing erratas on a chip. These flags
decide if a corresponding solution is applied to the chip(s).
This patch introduces below functions to handle errata flags:
- nvgpu_init_errata_flags
- nvgpu_set_errata
- nvgpu_is_errata_present
- nvgpu_print_errata_flags
- nvgpu_free_errata_flags
nvgpu_print_errata_flags: print below details of erratas present in chip
1. errata flag name
2. chip where the errata was first discovered
3. short description of the errata
Flags corresponding to erratas present in a chip are set during chip hal
init sequence.
