The flash chip on the board (Spansion S25FL256SAIF00) is rated to
support at least 50MHz for normal read requests according to the
datasheet. 133MHz for fast reads. However, ramips seems to be limited to
80MHz.

This option was a spi nor hack which is dropped in commit

Specify firmware partition format by compatible string.
formats in ramips:
- denx,uimage
- tplink,firmware
- seama
It's unlikely but the firmware splitting might not work any longer for
the following boards, due to a custom header:
- EX2700: two uImage headers
- BR-6478AC-V2: edimax-header
- 3G-6200N: edimax-header
- 3G-6200NL: edimax-header
- BR-6475ND: edimax-header
- TEW-638APB-V2: umedia-header
- RT-N56U: mkrtn56uimg
But it rather looks like the uImage splitter is fine with the extra
header.
The following dts are not touched, due to lack of a compatible string in
the matching firmware splitter submodule:
- CONFIG_MTD_SPLIT_JIMAGE_FW
DWR-116-A1.dts
DWR-118-A2.dts
DWR-512-B.dts
DWR-921-C1.dts

With ed25e3ac02 ("ramips: fix some clocks in mt7621.dtsi") the
cpuclock node was dropped from the mt7621.dtsi without removing the
references to this node from the GB-PC1/PC2 dts files.
Remove them now, to fix the build error.

Use diag.sh version used for other targets supporting different leds
for the different boot states.
The existing led sequences should be the same as before.

Set the pins to the required mode via the pinmux driver. It allows to
get rid of the pinmux related code in the sd card driver.

Starting with kernel 4.4, the use of partitions as direct subnodes of the

I was carrying a local commit that added the sdhci stuff and missed it
as a result.
Also fix the rgmii3 thing in the PC2 DTS file as that's bogus and causes

Use the generic board detection for the GnuBee Personal Cloud Two
instead of the target specific one as all recent additions are doing.
Fixup the pinmux to set all pins used as GPIO to the function GPIO.
Request pins where used.
Drop the i2c from the dts. There is nothing connected. While at it fix an
indentation issue and use references instead of duplicating the whole
node path.
Use the same switch config as for the GB-PC1 and drop the led trigger for
the not supported IP1001 phy connected to second rgmii.

The GnuBee Personal Cloud Two crowdfunded on https://www.crowdsupply.com
It is a low-cost, low-power, network-attached storage device.
Specifications:
- SoC: MediaTek MT7621AT
- RAM: DDR3 512 MB
- Flash: 32 MB
- Six SATA ports for 3.5" Drives
- One SDcard
- One USB 3.0
- Two USB 2.0
- Gigabit Ethernet: Three Ports
- UART 3.5mm Audio Jack or 3 pin header - 57600 8N1
- Three GPIOs available on a pin header
Flash instructions:
The GnuBee Personal Cloud Two ships with libreCMC installed.
libreCMC is a Free Software Foundation approved fork of LEDE/OpenWrt.
As such one can upgrade using the webinterface or sysupgrade.
Das U-Boot has multiple options for recovery or updates including :
- USB
- http
- tftp
Errata:
- While there are three ethernet ports, the third requires support for
the second GMAC. This will come in kernel 4.14.
- The first hard drive slot has a clearance issue with the two fan
headers. Workaround is to pull the headers out and connect the pins to
jumper wires.
- Using this device as a NAS is problematic with the 4.9 kernel as many
/dev/sdX reads throw silent errors. The current theory behind this is
some kind of unhandled DMA mapping error in the kernel. This is not an
issue with kernel 4.4.
