Subject: [PATCH 10/29] arm: kirkwood: move PCIe window init to legacy driver
|
|
|
|
Since we are going to enable the usage of the mvebu PCIe driver on
|
|
Kirkwood, we don't want the PCIe windows to be unconditionally created
|
|
by kirkwood_setup_wins(). Therefore, we move the PCIe window
|
|
initialization into the legacy PCIe driver
|
|
(arch/arm/mach-kirkwood/pcie.c).
|
|
|
|
The platforms using the legacy driver will see their windows
|
|
statically allocated by
|
|
arch/arm/mach-kirkwood/pcie.c:kirkwood_pcie_init(). The platforms
|
|
using the new driver in drivers/pci/ will see their windows
|
|
dynamically allocated directly by the driver.
