48239f5f8c gpu: nvgpu: Prune redundant cache maintenance
Remove redundant cache maintenance operations. Instance blocks and
graphics context buffers are uncached, so they do not need any cache
maintenance.

3e5c123862 gpu: nvgpu: Always initialize system vm
PMU, FECS and GPCCS use the same address space. We used to initialize
the address space only if PMU is enabled. Create the system address
space always.

FECS and GPCCS used to have slower bit bang and faster DMA method
for loading ucode. Slower method is needed when FECS and GPCCS do not
have an address space. Remove the slower method as not anymore
needed.

acd6d02069 gpu: nvgpu: gk20a: add fecs error intr handler
Add handler gk20a_gr_handle_fecs_error() in case we have
pending fecs error interrupt
And clear this interrupt after handling.

Also, in gk20a_gr_handle_fecs_error(), for now just print
the contents of NV_PGRAPH_FECS_INTR and clear it

4d93f77745 video: tegra: gk20a: Disable gfx before save zbc
This change disables gr engine before calling into pmu
for saving zbc and re-enables once it is finished.
Looks like NV_PPWR_PMU_BAR0_FECS_ERROR_CODE_PRI_TIMEOUT
error during access of NV_PLTCG_LTCS_LTSS_DSTG_ZBC_COLOR_CLEAR_VALUE
happens because of active concurrent memory traffic.
