On the Linksys WRT54GSv1, the adm6996 switch driver and the
gpio_button_hotplug module both claim GPIO 6, which is connected to the
Reset button. When the switch driver's request wins, the Reset button
cannot work. This makes it impossible to enter failsafe mode without a
serial console.
Stop requesting the "adm_rc" GPIO in the switch driver, since it is not
used anywhere.
Fixes FS#792.

PHY core treats any positive return value as the auto-negotiation done
indication. Since we do not actually check any device register in this
callback then update it to return positive value with a neutral meaning
instead of the register flag to avoid confusing for future readers.

The Marvel 88E6060 switch has an MDIO interface, but does not emulate
regular PHY behavior for the host. The network core can not detect using
the generic code, whether the connection via the attached PHY can be
used or not. The PHY's state machine is stuck in a state of
auto-negotiation and does not go any further so the Ethernet interface
of the router stay forever in the not-runing state.
Fix this issue by implementing the aneg_done callback to be able to
inform the network core that the Ethernet interface link to which the
switch is connected can be marked as RUNNING.

The RouterBOOT bootloader does not care where the kernel lives in the SPI
flash, all that matters is that the kernel is wrapped in the custom yaffs
container as generated by kernel2minor.
This container has a fixed signature as follows:
00000000 00 00 00 01 00 00 00 01 ff ff 6b 65 72 6e 65 6c |..........kernel|
This patch adds mtdsplit support for identifying that signature and
triggering the search for the rootfs. rootfs is expected at EB boundary since
we use wget mtd_find_rootfs_from(). We make no use of the yaffs file size
field because it contains invalid data in the image generated by kernel2minor.

This patch adds supports for the WNR2000v1 board with 4MB flash, and
produces device-specific factory, rootfs, and sysupgrade files for the
WNR2000v1. This board is errorneously claimed as supported on the OpenWRT
wiki as AP81, but AP81 image would not work because of APT81 image
requiring having 8MB of flash, while WNR2000v1 has only 4MB.
The image requires the u-boot bootloader to be modified to fuhry's
bootloader first.
Short specification:
- CPU: Atheros AR9132
- 4x 10/100 Mbps Ethernet, 1x WAN 10/100 Mbps
- 4 MB of Flash
- 32 MB of RAM
- UART header (J1) on board
- 1x button
Factory/Initial flash instructions:
- Set up a TFTP server on your local machine.
- Download the uImage for ar71xx-generic and the rootfs image for
ar71xx-generic-wnr2000 and save in the tftp server root.
- Gain serial access to the router via the UART port (telnetenable over
the network only won't work!).
- Upgrade the u-boot bootloader to fuhry's version by running the
script: http://fuhry.com/b/wnr2000/install-repart.sh
- When the router restarts, interrupt u-boot and gain access to u-boot command line.
- Repartititon the board and flash initial uImage and rootfs as follow.
Commands to type in u-boot:
# tells u-boot that we have a tftp server on 192.168.1.10
setenv serverip 192.168.1.10
# tells u-boot that the router should take the address 192.168.1.1
setenv ipaddr 192.168.1.1
# erase the region from 0x050000-0x3f0000
erase 0xbf050000 +0x3A0000
# loads sqfs.bin on TFTP server, and put it to memory address 0x81000000
tftpboot 0x81000000 sqfs.bin
# it will tell you the length of sqfs.bin in hex, let's say ZZZZZZ
# copy bit by bit 0xZZZZZZ bytes from offset 0x050000
cp.b 0x81000000 0xbf050000 0xZZZZZZ
# same to the uImage.bin, write it right next to sqfs.bin
# again, 0xYYYYYY is the length that tftpboot reports
tftpboot 0x81000000 uImage.bin
cp.b 0x81000000 0xbf2a0000 0xYYYYYY
# We need to tell the kernel what board it is booting into, and where to find the partitions
setenv bootargs "board=WNR2000 console=ttyS0,115200 mtdparts=spi0.0:256k(u-boot)ro,64k(u-boot-env)ro,3712k(firmware),64k(art)ro rootfstype=squashfs,jffs2 noinitrd"
# Tell u-boot where to find the uImage
setenv bootcmd "bootm 0xbf2a0000"
# Tell u-boot to save parameters to the u-boot-env partitions
saveenv
# Reset the board
reset
Tested on:
- WNR2000v1 board.
- Initial flash works.
Known bugs:
- I don't know why factory image doesn't work on initial flash on stock
firmware in u-boot recovery mode while it should.
- Sysupgrade does not yet work, if you do -f it will mess up your
installation (requiring a reinstall of sqfs and uImage).

If probe is called twice, once for PHY0 and a second time for PHY4,
the same switch device will be added twice to ar8xxx_dev_list, while
supposedly this list should have one element per hardware switch present
in the system.
While no negative impact have been observed, it does happen if a

The commit "generic: ar8216: add sanity check to ar8216_probe"
(774da6c7a4) stated that PHY IDs
should be checked at address 0-4. However, the PHY 4 was
never check by the loop. This patch extends the check to be
similar to the Atheors SDK. It tries all 4 ports and skips
unconnected PHYs if necessary. If it cannot find any familiar
PHYs, it will prevent the phy driver from initializing.
This patch is necessary for the C-60. It doesn't have a
PHY at port 3, so this caused the check in ar8xxx_is_possible
to fail. As a result, the ethernet ports on the C-60 didn't
work.

Some devices (like the Cisco Meraki Z1 Cloud Managed Teleworker Gateway)
need to be able to initialize the PCIe wifi device. Normally, this is done
during the early stages of booting linux, because the necessary init code
is read from the memory mapped SPI and passed to pci_enable_ath9k_fixup.
However,this isn't possible for devices which have the init code for the
Atheros chip stored on NAND in an UBI volume. Hence, this module can be
used to initialze the chip when the user-space is ready to extract the
init code.
Martin Blumenstingl made a few fixes and added support for lantiq:
kernel: owl-loader: add support for OWL emulation PCI devices
kernel: owl-loader: don't re-scan the bus when ath9k_pci_fixup failed
kernel: owl-loader: use dev_* instead of pr_* logging functions
kernel: owl-loader: auto-generate the eeprom filename as fallback
kernel: owl-loader: add a debug message when swapping the eeprom data
kernel: owl-loader: add missing newlines in log messages
kernel: owl-loader: add support for the lantiq platform
These patches have been integrated. Thanks!
