The legacy way to initialize discovery_tmr_size is using DISCOVERY_TMR_SIZE, while after we reduce DISCOVERY_TMR_SIZE from 64KB to 4KB, variable discovery_tmr_size is also reduced to 4KB, this is not correct, it still should be 64KB, discovery_tmr_size will be used to calculate ip_discovery reserved mem's start address and size.

Error appears when some i2c device driver tries to probe for devices using adapter registered by `smu_v11_0_i2c_eeprom_control_init()`. Code supporting this adapter requires `adev->psp.ras.ras` to be not NULL, which is true only when `amdgpu_ras_init()` detects HW support by calling `amdgpu_ras_check_supported()`. Before 9015d60c9ee1, adapter was registered by -> amdgpu_device_ip_init() -> amdgpu_ras_recovery_init() -> amdgpu_ras_eeprom_init() -> smu_v11_0_i2c_eeprom_control_init() after verifying that `adev->psp.ras.ras` is not NULL in `amdgpu_ras_recovery_init()`. Currently it is registered unconditionally by -> amdgpu_device_ip_init() -> pp_sw_init() -> hwmgr_sw_init() -> vega20_smu_init() -> smu_v11_0_i2c_eeprom_control_init() Fix simply adds HW support check (ras == NULL => no support) before calling `smu_v11_0_i2c_eeprom_control_{init,fini}()`. Please note that there is a chance that similar fix is also required for CHIP_ARCTURUS. I do not know whether any actual Arcturus hardware without RAS exist, and whether calling `smu_i2c_eeprom_init()` makes any sense when there is no HW support.

2020-07-01drm/amd/display: Fill in dmub_srv fw_version from firmware metadataNicholas Kazlauskas1-0/+10
[Why] DMCUB firmware version is now available from firmware metadata block. We should be passing this into dmub_srv so we can know when to apply firmware version specific functionality like using CW4 only instead of the REGION4. [How] We don't have the helpers for DM to actually extract out firmware metadata block themselves. We could add that and add helpers in DM to grab this, but not every creation sequence has firmware instruction before dmub_srv_create. Easiest way to handle this is to fill this in automatically per DM in the place we do have it - when calculating the region parameters. But only fill it in if DM already hasn't in case we need to override with a specific version. We aren't do anything firmware version specific in dmub_srv_create today that does require fw_version, so while it's a little unituitive to do it when calculating region parameters it works for now.

2020-07-01drm/amd/display: Force ODM combine on 5K+ 420 modesChris Park1-0/+10
[Why] All YCbCr420 resolutions 5K and above have tiling and discoloration issues. The issue can be remedied by forcing ODM combine from 5K to 8K. 10K resolution requires ODM 4:1. The mechanism of what the real problem is, that is inherent in ODM combine programming, doesn't seem to be pointed at singular register programming (CLK, MPC, DCSURF, etc.), and needs more in-depth programming sequence review for these new use case scenarios. Until then, workaround to enable ODM combine is proposed. While it is not our policy, HW spreadsheet also recommends turning on ODM for these scenario to lower the voltage.
