+Subject: [PATCH] MIPS: AR724x: Fix AR724X_PCI_MEM_SIZE
|
|
|
+
|
|
|
+commit 4c960910e2fb3a301ee4a504fa6b2c5204efeab0 upstream.
|
|
|
+
|
|
|
+The base address of the PCI memory is
|
|
|
+0x10000000 and the base address of the
|
|
|
+PCI configuration space is 0x14000000
|
|
|
+on the AR724x SoCs.
|
|
|
+
|
|
|
+The AR724X_PCI_MEM_SIZE is defined as
|
|
|
+0x08000000 which is wrong because that
|
|
|
+overlaps with the configuration space.
|
|
|
+
|
|
|
+The patch fixes the value of the
|
|
|
+AR724X_PCI_MEM_SIZE constant, in order
|
|
|
+to avoid this resource conflicts.
