| Subject: [PATCH] arm64: dts: nuvoton: npcm845: set FIU UMA read |
| |
| Set default UMA read instead of direct read for FIU0, FIU1 and FIU3 in |
| NPCM8XX BMC common device tree by removing FIUs memory mapping. |
| |
| This change was made because FIU direct read can cause overloads |
| in the internal bus. |
