Subject: [PATCH] PCI: aardvark: Optimize writing PCI_EXP_RTCTL_PMEIE and
|
|
PCI_EXP_RTSTA_PME on emulated bridge
|
|
MIME-Version: 1.0

|
To optimize advk_pci_bridge_emul_pcie_conf_write() code, touch
|
|
PCIE_ISR0_REG and PCIE_ISR0_MASK_REG registers only when it is really
|
|
needed, when processing PCI_EXP_RTCTL_PMEIE and PCI_EXP_RTSTA_PME bits.
