Subject: [PATCHv5 1/2] PCI: layerscape: Add the bar_fixed_64bit property in EP driver.

The PCIe controller of layerscape just have 4 BARs, BAR0 and BAR1
is 32bit, BAR2 and BAR4 is 64bit, this is determined by hardware,
so set the bar_fixed_64bit with 0x14.

v2:
- Replace value 0x14 with a macro.
v3:
- No change.
v4:
- send the patch again with '--to'.
v5:
- fix the commit message.

I check other platforms, it is 'static const struct pci_epc_features', I can get the correct

You should fix your email client set-up to avoid sticking an [EXT]
tag to your emails $SUBJECT.

See above, this "Caution" stuff should disappear.

Also, quoting the email header is useless, please configure your email
client to remove it.

Do you see any commit with a $SUBJECT ending with a period ?

There is not. So remove it from yours too.

scripts/get_maintainer.pl -f drivers/pci/controller/dwc/pci-layerscape-ep.c
Now, with the output you get justify all the people you send this email
to.

So, again, trim the CC list and it is the last time I tell you.

Before sending patches on mailing lists use git --dry-run to check
the emails you are sending.

Thanks,
Lorenzo

Do you mean that I use scripts/get_maintainer.pl -f drivers/pci/controller/
dwc/pci-layerscape-ep.c to get the mail list who I need to send? I use the
command of ' scripts/get_maintainer.pl *.patch' to get the mail list before.
If yes, I will use the command that you provided. Thanks a lot.
