usb: renesas-xhci: Prefer firmware loading on unknown ROM state
The recent attempt to handle an unknown ROM state in the commit
d143825baf15 ("usb: renesas-xhci: Fix handling of unknown ROM state")
usb: renesas-xhci: Prefer firmware loading on unknown ROM state
The recent attempt to handle an unknown ROM state in the commit
d143825baf15 ("usb: renesas-xhci: Fix handling of unknown ROM state")
resulted in a regression and reverted later by the commit 44cf53602f5a
("Revert "usb: renesas-xhci: Fix handling of unknown ROM state"").
The problem of the former fix was that it treated the failure of
firmware loading as a fatal error. Since the firmware files aren't
included in the standard linux-firmware tree, most users don't have
them, hence they got the non-working system after that. The revert
fixed the regression, but also it didn't make the firmware loading
triggered even on the devices that do need it. So we need still a fix
for them.
This is another attempt to handle the unknown ROM state. Like the
previous fix, this also tries to load the firmware when ROM shows
unknown state. In this patch, however, the failure of a firmware
loading (such as a missing firmware file) isn't handled as a fatal
error any longer when ROM has been already detected, but it falls back
to the ROM mode like before. The error is returned only when no ROM
is detected and the firmware loading failed.
Along with it, for simplifying the code flow, the detection and the
check of ROM is factored out from renesas_fw_check_running() and done
in the caller side, renesas_xhci_check_request_fw(). It avoids the
redundant ROM checks.
The patch was tested on Lenovo Thinkpad T14 gen (BIOS 1.34). Also it
was confirmed that no regression is seen on another Thinkpad T14
machine that has worked without the patch, too.

usb: renesas-xhci: Add the renesas xhci driver
This add a new driver for renesas xhci which is basically a firmware
loader for uPD720201 and uPD720202 w/o ROM. The xhci-pci driver will
invoke this driver for loading/unloading on relevant devices.
This patch adds a firmware loader for the uPD720201K8-711-BAC-A
and uPD720202K8-711-BAA-A variant. Both of these chips are listed
in Renesas' R19UH0078EJ0500 Rev.5.00 "User's Manual: Hardware" as
devices which need the firmware loader on page 2 in order to
work as they "do not support the External ROM".
The "Firmware Download Sequence" is describe in chapter
"7.1 FW Download Interface" R19UH0078EJ0500 Rev.5.00 page 131.
The firmware "K2013080.mem" is available from a USB3.0 Host to
PCIe Adapter (PP2U-E card) "Firmware download" archive. An
alternative version can be sourced from Netgear's WNDR4700 GPL
archives.
The release notes of the PP2U-E's "Firmware Download" ver 2.0.1.3
(2012-06-15) state that the firmware is for the following devices:
- uPD720201 ES 2.0 sample whose revision ID is 2.
- uPD720201 ES 2.1 sample & CS sample & Mass product, ID is 3.
- uPD720202 ES 2.0 sample & CS sample & Mass product, ID is 2.

usb: renesas-xhci: Prefer firmware loading on unknown ROM state

usb: renesas-xhci: Prefer firmware loading on unknown ROM state
commit c82cacd2f1e622a461a77d275a75d7e19e7635a3 upstream.
The recent attempt to handle an unknown ROM state in the commit
d143825baf15 ("usb: renesas-xhci: Fix handling of unknown ROM state")
resulted in a regression and reverted later by the commit 44cf53602f5a
("Revert "usb: renesas-xhci: Fix handling of unknown ROM state"").
The problem of the former fix was that it treated the failure of
firmware loading as a fatal error. Since the firmware files aren't
included in the standard linux-firmware tree, most users don't have
them, hence they got the non-working system after that. The revert
fixed the regression, but also it didn't make the firmware loading
triggered even on the devices that do need it. So we need still a fix
for them.
This is another attempt to handle the unknown ROM state. Like the
previous fix, this also tries to load the firmware when ROM shows
unknown state. In this patch, however, the failure of a firmware
loading (such as a missing firmware file) isn't handled as a fatal
error any longer when ROM has been already detected, but it falls back
to the ROM mode like before. The error is returned only when no ROM
is detected and the firmware loading failed.
Along with it, for simplifying the code flow, the detection and the
check of ROM is factored out from renesas_fw_check_running() and done
in the caller side, renesas_xhci_check_request_fw(). It avoids the
redundant ROM checks.
The patch was tested on Lenovo Thinkpad T14 gen (BIOS 1.34). Also it
was confirmed that no regression is seen on another Thinkpad T14
machine that has worked without the patch, too.

The ROM load sometimes seems to return an unknown status
(RENESAS_ROM_STATUS_NO_RESULT) instead of success / fail.
If the ROM load indeed failed this leads to failures when trying to

usb: renesas-xhci: include correct header for get_unaligned_le16()
get_unaligned_le16() is defined in linux/unaligned/access_ok.h header

failures on ia64. Using asm/unaligned.h seem to be the right thing
and used in other drivers.
