If reo_dst_ctrl register writing failed, this is a fatal error for
IPA pipe going to down case as RX frames will still be routed to
IPA rings then hit NOC error. retry register writing to see any
chance to write successfully, if fail always, trigger SSR or panic.

In ipq5018 CE registers(0x08400000) kept outside WCSS(0x0C000000) block.
As both regions are more than 60MB apart, not feasible to allocate

Currently as part of runtime PM, only the active

Add prefetch_timer configuration for CE rings.
Set prefetch_timer=1 configuration for qca6490 destination CEs,
prefetch_timer=0 configuration for other targets CEs.
Basically setting to 1us asking CE hw to update ring tail pointer to
update within 1us. FW side CE SW sets all rings to 1us already.
Idea behind this change is, we have seen pre-silicon issue where SRC
ring TP read by SW was not seen updated value when prefetch was set
to 8us. Changing prefetch timer value to 1us helps to resolve
pre-silicon issue.
So host side rings need to update the prefetch timer to 1us.

The delayed register write enqueue fills a queue element
with the required data which can be dequeued in a workqueue
running on a different CPU. Since these operations are not
lock protected, there can be stale value access when memory
write has not been flushed to the actual address.
Using write memory barrier before setting the valid flag for
a queue element will make sure that the dequeuing worker
thread will always see the updated values if the element valid
flag is set and thereby avoid any race condition.

The delayed register write for srngs will have
the value of the HP/TP at the time of enqueue,
but the final value which is written to the
hp_addr/tp_addr will be determined based on
HP/TP value at the time of dequeue of the
entry for a particular srng.
Hence to know what was the exact value which
was written to the HP/TP address, add one more
element in the delayed register write entry.
This element will contain the value of the
HP/TP which was actually written to the address.

In case the bus is in low power mode, the register writes (followed by a
memory barrier) may take a long time (~4ms). This can cause the caller
to block till the PCIe write is completed. Thus, even though PCI
writes are posted, it can still block the caller.
Hence, in case the bus is in low power mode (not in M0), or not in high
throughput scenarios, queue the register write in a workqueue. The
register write will happen in the delayed work context. In other cases,
i.e ,when the bus is not in low power mode or in high thoughput
scenarios, do the register writes in caller context.

When SAP do connection with first Ref-STA or dis-connection with

register. one of the register offset is 0xA38004, host need to write
remap window register (offset 0x310C) with value 0x14 first, but
sometimes this remap window writing not work, so just use the remap
window value 0x3F left by last writing, final Dst register offset will
be 0x1FB8004 which is out of valid range.
Find that if we read back the remap window after writing is done,
remap window writing failure issue is gone. as a WAR, check register
writing result for this specific register REO_R0_DST_RING_CTRL_IX_0

Write into hal register using three floating windows instead of one.
This change is done to avoid frequent window changes for writing into
DP and CE registers. Instead 3 windows are used. One window is statically
mapped to CE block and another window is mapped statically to DP block.
Due to this design there is no need to change the window register to
write into these blocks and write can be done on corresponding window
with single iowrite32. Similar loginc is used for ioread32.
Also modified the hp_addr and tp_addr in initialisation stage so that
hal_write will not have multiple if checks.

Observed that when IPA offload is enabled, RX packets
are not routed correctly to IPA ring. Currently only
IX0 of REO_DESTINATION_CTRL_IX registers are remapped,
which only covers 3-bit reo_destination_indication of

Fix is to remap REO_DESTINATION_CTRL_IX2|3 registers

31 can also be routed REO2IPA ring when IPA offload
is enabled. Upon IPA offload is disabled, save values
of IX2 and IX3 are reset back to HW.
