Add 'dma-coherent' property to node for the backend running on
Cortex-A core, to utilize the cacahe coherent feature within
the cluster to improve the performance.Signed-off-by: Hou Zhiqiang

Add the device specific DMA memory pool to allocate DMA coherent
memory for both vring and data buffer.Signed-off-by: Hou Zhiqiang
-
Add initialization of device specific DMA pool for hypervisor-less
case.Signed-off-by: Hou Zhiqiang
-
Currently, the coherent DMA memory is always mapped as writecombine
and uncached, ignored the 'dma-coherent' property in device node,
this patch is to map the memory as writeback and cached when the
device has 'dma-coherent' property.Signed-off-by: Hou Zhiqiang

As SGI is used as IPI in Linux, so let's replace SGI with some SPI irqs
which is not used by as hardware, SPI irq can also be triggered by
writing to SGI interrupt by CPU Core.Signed-off-by: Hou Zhiqiang

Add ICC_CMD_DUMP_TIME option mode for ipi_baremetal_handle
to support dump time interrupt from baremetal core.For this function add two option modes, one is
ICC_CMD_TX_DATA which used for data transfer, the other is
ICC_CMD_DUMP_TIME which used for print interrupt handle
information in receiver core.Signed-off-by: Chunguang Li

The queue 0 is always preemption when preemption is enabled. This patch
modify the stmmac_get_preempt() function to display queue 0 as
preemption to ethtool application.Signed-off-by: Xiaoliang Yang

This patch doesn't enable the mac merge layer until the lldp application
verify the remote port supports preemption. The lldp verify feature can
be enabled or disabled by ethtool application.Signed-off-by: Xiaoliang Yang

Based on "99.4.2 Determining that the link partner supports preemption"
of IEEE 802.3-2018, the felix driver need to support lldp verify
feature.Signed-off-by: Xiaoliang Yang
-
The ethtool module has added a preemption reset API, the dsa driver also
needs to add this API to support reset preemption driver.Signed-off-by: Xiaoliang Yang
-
The preemption should not be active until the lldp verify ensure that
preemption is enabled on remote port. That needs a reset function to
reset the preemption to make the preemption active. The user space
application will use this API.Signed-off-by: Xiaoliang Yang
-
In "99.4.2 Determining that the link partner supports preemption" of
IEEE 802.3-2018, it defines that the preemption needs LLDP exchange to
verify the preemption status of link partner. This patch adds lldp
verify parameter and modify some parameter to fit this feature.User space command example:
$ethtool --set-frame-preemption swp0 lldp-verify on \
