Subject: [PATCH] PCI: aardvark: Fix initialization with old Marvell's Arm

Old ATF automatically power on pcie phy and does not provide SMC call for
|
|
phy power on functionality which leads to aardvark initialization failure:
|
|
|
|
[ 0.330134] mvebu-a3700-comphy d0018300.phy: unsupported SMC call, try updating your firmware
|
|
[ 0.338846] phy phy-d0018300.phy.1: phy poweron failed --> -95
|
|
[ 0.344753] advk-pcie d0070000.pcie: Failed to initialize PHY (-95)
|
|
[ 0.351160] advk-pcie: probe of d0070000.pcie failed with error -95
|
|
|
|
This patch fixes above failure by ignoring 'not supported' error in
|
|
aardvark driver. In this case it is expected that phy is already power on.
