The Linux kernel driver sets the number of event segments and entries
to 1 , while the initial import of the xhci code set that values to 3
for reasons unknown. While most controllers are fine with more event
segments with more entries, there are standard-conformant controllers
(ie. Renesas RCar xHCI) which only support 1 event segment.
Set the number of event segments and event entries back to 1 to allow
such controllers to work with U-Boot xHCI stack. Note that the Renesas
controller correctly indicates ERST Max = 1 in HCSPARAMS2[7:4] .

Since commit 842778a091 ("usb: gadget: g_dnl: only set iSerialNumber
if we have a serial#") "fastboot devices" stopped to show correct device
serial number for TI boards, showing this line instead:
???????????? fastboot
This is because serial# env variable could be set after g_dnl gadget was
initialized (e.g. by using env_set() in the board file).
To fix this, let's update internal serial number variable (g_dnl_serial)
when "serial#" env var is changed.

It turns out xHCI driver still misses a part that in the device's

So far U-Boot does not program this field, and it does not prevent
SS device directly attached to root port, or HS device behind an HS
hub, from working, due to the fact that 'route string' is used by
the xHC to target SS packets. But in order to enumerate devices
behind an SS hub, this field must be programmed.

visible when we have non zero length of g_dnl_serial.
However, on some platforms (e.g. Siemens) the serial number is set at
g_dnl_bind_fixup(), so with the current code we will always omit the
serial (since it is not set).
This commit moves the g_dnl_bind_fixup() call before the g_dnl_serial
length test.

Current implementation doesn't allow utilization of platform-specific
reads and writes.
But some arches or platforms may want to use their accessors that do
some extra work like adding barriers for data serialization etc.
Interesting enough OHCI accessors already do that so just aligning
EHCI to it now.
This is a resend of http://patchwork.ozlabs.org/patch/726714/
Back in the day this patch broke some PPC and Sandbox boards
as they we missing inclusion of "asm/io.h". Those missing items were
fixed with:
1) http://patchwork.ozlabs.org/patch/751397/
2) http://patchwork.ozlabs.org/patch/771099/
So now it should be safe to apply this patch.
FWIW TravisCI builds everything with all 3 patches in place,

SNP/SRP capability. So add the property of "hnp-srp-disable" in the DTS
to config the contrller work in force mode of host.

We used to have opencoded ehci_readl()/writel() which required no

Now with attempt to switch to generic readl()/writel() accessors
we see a missing declaration of those accessors in ehci-ppc4xx.
Something like that happens if applied

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.
In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only
All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.
Note this involves changing some dead code - the imx_lpi2c.c file.
