From 892a423de8520fda2735835faed7870c3bbf420f Mon Sep 17 00:00:00 2001 From: Raul E Rangel Date: Fri, 22 Jan 2021 10:04:59 -0700 Subject: soc/amd/picasso/acpi: Remove DMA addresses for UARTs This is not the correct way to specify the FixedDMA devices. I'm removing for now since it adds confusion. BUG=none BRANCH=zork TEST=Boot zork to linux and make sure UART still works Signed-off-by: Raul E Rangel Change-Id: I17b9c8dbe4f9c4b64ee1bd69cb9b30998e727632 Reviewed-on: https://review.coreboot.org/c/coreboot/+/49843 Tested-by: build bot (Jenkins) Reviewed-by: Felix Held --- src/soc/amd/picasso/acpi/sb_fch.asl | 8 -------- 1 file changed, 8 deletions(-) (limited to 'src/soc') diff --git a/src/soc/amd/picasso/acpi/sb_fch.asl b/src/soc/amd/picasso/acpi/sb_fch.asl index 32268da998..6c3c51dedf 100644 --- a/src/soc/amd/picasso/acpi/sb_fch.asl +++ b/src/soc/amd/picasso/acpi/sb_fch.asl @@ -106,7 +106,6 @@ Device (FUR0) Exclusive, , , IRQR) { 0 } Memory32Fixed (ReadWrite, APU_UART0_BASE, 0x1000) - Memory32Fixed (ReadWrite, APU_DMAC0_BASE, 0x1000) } CreateDWordField (Local0, IRQR._INT, IRQN) If (PICM) { @@ -117,7 +116,6 @@ Device (FUR0) If (IRQN == 0x1f) { Return (ResourceTemplate() { Memory32Fixed (ReadWrite, APU_UART0_BASE, 0x1000) - Memory32Fixed (ReadWrite, APU_DMAC0_BASE, 0x1000) }) } Else { Return (Local0) @@ -139,7 +137,6 @@ Device (FUR1) { Exclusive, , , IRQR) { 0 } Memory32Fixed (ReadWrite, APU_UART1_BASE, 0x1000) - Memory32Fixed (ReadWrite, APU_DMAC1_BASE, 0x1000) } CreateDWordField (Local0, IRQR._INT, IRQN) If (PICM) { @@ -150,7 +147,6 @@ Device (FUR1) { If (IRQN == 0x1f) { Return (ResourceTemplate() { Memory32Fixed (ReadWrite, APU_UART1_BASE, 0x1000) - Memory32Fixed (ReadWrite, APU_DMAC1_BASE, 0x1000) }) } Else { Return (Local0) @@ -172,7 +168,6 @@ Device (FUR2) { Exclusive, , , IRQR) { 0 } Memory32Fixed (ReadWrite, APU_UART2_BASE, 0x1000) - Memory32Fixed (ReadWrite, APU_DMAC2_BASE, 0x1000) } CreateDWordField (Local0, IRQR._INT, IRQN) If (PICM) { @@ -183,7 +178,6 @@ Device (FUR2) { If (IRQN == 0x1f) { Return (ResourceTemplate() { Memory32Fixed (ReadWrite, APU_UART2_BASE, 0x1000) - Memory32Fixed (ReadWrite, APU_DMAC2_BASE, 0x1000) }) } Else { Return (Local0) @@ -205,7 +199,6 @@ Device (FUR3) { Exclusive, , , IRQR) { 0 } Memory32Fixed (ReadWrite, APU_UART3_BASE, 0x1000) - Memory32Fixed (ReadWrite, APU_DMAC3_BASE, 0x1000) } CreateDWordField (Local0, IRQR._INT, IRQN) If (PICM) { @@ -216,7 +209,6 @@ Device (FUR3) { If (IRQN == 0x1f) { Return (ResourceTemplate() { Memory32Fixed (ReadWrite, APU_UART3_BASE, 0x1000) - Memory32Fixed (ReadWrite, APU_DMAC3_BASE, 0x1000) }) } Else { Return (Local0) -- cgit v1.2.3
