bcm53xx: add support for Cisco Meraki MX64/MX65
This commit adds support for the Cisco Meraki MX64 and MX65 devices which
use the Broadcom NSP SoC, which is compatible with the bcm53xx platform.
MX64 Hardware info:
- CPU: Broadcom BCM58625 Cortex A9 @ 1200Mhz
- RAM: 2 GB (4 x 4Gb SK Hynix H5TC4G83CFR)
- Storage: 1 GB (Micron MT29F8G08ABACA)
- Networking: BCM58625 internal switch (5x 1GbE ports)
- USB: 1x USB2.0
- Serial: Internal header
MX65 Hardware info:
- CPU: Broadcom BCM58625 Cortex A9 @ 1200Mhz
- RAM: 2 GB (4 x 4Gb SK Hynix H5TC4G83CFR)
- Storage: 1 GB (Micron MT29F8G08ABACA)
- Networking: BCM58625 switch (2x 1GbE ports, used for WAN ports 1 & 2)
2x Qualcomm QCA8337 switches (10x 1GbE ports, used for LAN ports 3-12)
- PSE: Broadcom BCM59111KMLG connected to LAN ports 11 & 12
- USB: 1x USB2.0
- Serial: Internal header
Notes:
- The Meraki provided GPL source are available at [2].
- Wireless capability on the MX64W and MX65W exists in the form of 2x
Broadcom BCM43520KMLG, which is not supported. These devices will work
otherwise as standard MX64 or MX65 devices.
- Early MX64 units use an A0 variant of the BCM958625 SoC which lacks
cache coherency and uses a different "secondary-boot-reg". As a
consequence a different device tree is needed.
- Installation of OpenWrt requires changing u-boot to a custom version.
This is due to the stock u-boot "nand read" command being limited to
load only 2MB, in spite of the bootkernel1 and bootkernel2 partitions
both being 3MB in the stock layout. It is also required to allow
booting via USB, enabling cache coherency and setting up the QCA
switches and Serdes link on the MX65. The modified sources for U-boot
are available for the MX64[3] and MX65[4].
- Initial work on this device used a small bootloader within the OEM
partition scheme. To allow booting of larger kernels, UBI and bootm
support has been added, along with ability to store env variables to
the NAND. The Shmoo and newly created env partitions have been moved
to the extra space available after the nvram data.
- Users who installed the previous non-UBI supporting bootloader will
need to convert to the new one before flashing a compatible image.
These steps are detailed below.

Installation guide:
Initial installation steps:
1. Compile or obtain OpenWrt files for the MX64 or MX65, including
u-boot[3][4], initramfs and sysupgrade images.
2. A USB disk with DOS partition scheme and primary FAT partition is
required.
3. If installing onto an MX64, set up a local web server.
4. On the device, boot into diagnostic mode by holding reset when
powering on the device. Continue to hold reset until the orange LED
begins to flash white. On used units the white flash may be difficult
to see.
5. Plug an Ethernet cable into the first LAN port, set the host to
192.168.1.2 and confirm telnet connectivity to 192.168.1.1.
U-boot installation - MX64 Only:
1. Newer fw versions require extra steps to support OpenWrt. To check,
please connect via telnet and run:
`cat /sys/block/mtdblock0/ro`
If the result is 1, your mtd0 is locked will need to perform extra
steps 4 and 5 in this section. If the result is 0 then skip these.
2. Check which SoC is in use by running the following command:
`devmem 0x18000000`
If devmem is not found then try:
`devmem2 0x18000000`
If the output begins with anything between "0x3F00-0x3F03" you will
need to use the A0 release. For any other output, eg "0x3F04" or
higher, use the regular MX64 image.
3 Confirm the size of the device's boot(mtd0) partition. In most
cases it should be 0x100000 or larger. If this is the case, please
proceed to use the uboot_mx64 image. If the reported size is
0x80000, please use the uboot_mx64_small image, then follow the
later guide to change to the larger image.
`cat /proc/mtd`
Example output:
`# cat /proc/mtd
cat /proc/mtd
dev: size erasesize name
mtd0: 00100000 00040000 "boot"
mtd1: 00080000 00040000 "shmoo"
mtd2: 00300000 00040000 "bootkernel1"
mtd3: 00100000 00040000 "nvram"
mtd4: 00300000 00040000 "bootkernel2"
mtd5: 3f700000 00040000 "ubi"
mtd6: 40000000 00040000 "all"`
4. Set up a webserver to serve the appropriate uboot_mx64 from the
following location and verify the SHA512:
https://github.com/clayface/U-boot-MX64-20190430_MX64
5. (Only if mtd0 is locked) You will also need the mtd-rw.ko kernel
module to unlock the partition from the same repo. An mtd executable
is also needed to write the mtd block. Place these on the web server
as well.
6. (Only if mtd0 is locked) Use wget to retrieve the files on the MX64:
`wget http://192.168.1.2/mtd-rw.ko`
`insmod mtd-rw.ko i_want_a_brick=1`
and confirm the unlock is set with dmesg
`mtd-rw: mtd0: setting writeable flag`
7. Download the appropriate u-boot image according to step 3. If you
did not need to unlock the mtd0 partition then use dd to write the
file, with caution:
`wget http://192.168.1.2/uboot_mx64`
`dd if=uboot_mx64 of=/dev/mtdblock0`
If you needed to unlock the mtd0 partition using the mtd-rw module,
run these commands instead to install u-boot instead:
`wget http://192.168.1.2/mtd`
`chmod +x mtd`
`wget http://192.168.1.2/uboot_mx64`
`./mtd write uboot_mx64 /dev/mtd0`
8. Once this has successfully completed, power off the device. If you
did not need to install the small u-boot image, proceed to
"OpenWrt Installation". Otherwise proceed to "UBI supporting
bootloader installation".
U-boot installation - MX65 Only:
1. Obtain telnet access to the MX65.
2. Confirm the size of the device's boot(mtd0) partition. In most
cases it should be 0x100000 or larger. If this is the case, please
proceed to use the uboot_mx65 image. If the reported size is
0x80000, please use the uboot_mx65_small image, then follow the
later guide to change to the larger image.
`cat /proc/mtd`
3. Prepare a USB drive formatted to FAT. Download the appropriate
uboot_mx65 to the USB drive from the following location and verify
the SHA512:
https://github.com/clayface/U-boot-MX64-20190430_MX65
3. Once you have telnet access to the MX65, plug in the USB disk and
run the following commands, with caution. The USB disk should
automount but if it does not, you will need to power off and on
again with reset held. Depending on step 2, use the uboot_mx65 or
uboot_mx65_small image accordingly:
`cd /tmp/media/sda1`
`dd if=uboot_mx65 of=/dev/mtdblock0`
4. Once this has successfully completed, power off the device. If you
did not need to install the small u-boot image, proceed to
"OpenWrt Installation". Otherwise proceed to "UBI supporting
bootloader installation".
UBI supporting bootloader installation:
These steps need to be followed if the older u-boot image was
installed, either because the Meraki diagnostic partition scheme used
0x80000 as the mtd0 size, or because you installed the u-boot provided
while OpenWrt support was still under development. If using OpenWrt,
please make a backup before proceeding.
1. Obtain the relevant image from the MX64(A0) or MX65 u-boot repo:
`openwrt-bcm5862x-generic-meraki_XXXX-initramfs-kernel.bin`
2. With the USB drive already inserted, power on the device while
holding the reset button. A white/orange flashing pattern will
occur shortly after power on. Let go of the reset button. The
device is now booting into OpenWrt initramfs stored on the USB
disk.
3. Connect by SSH to 192.168.1.1 and flash the embedded u-boot image,
changing X as appropriate:
`mtd write /root/uboot_mx6X /dev/mtd0`
You do not need to reboot as this image can handle "Kernel-in-UBI"
OpenWrt installation.
4. You can proceed to obtain and flash the appropriate OpenWrt image
at "OpenWrt Installation" Step 3.
5. Reboot will take significantly longer due to Shmoo calibration. In
case the device does not come online after several minute, power-
cycle the device and see if it boots. If you see an orange/white
flashing pattern, this indicates UBI booting was not successful and
you will need to copy a new bcm53xx image to a USB disk before
booting it and attempting to install OpenWrt again - refer to
"OpenWrt Installation" step 1. Do not attempt to reflash u-boot in
this scenario.
OpenWrt Installation:
1. Having obtained an OpenWrt image, please copy the file
`openwrt-bcm53xx-generic-meraki_XXXX-initramfs.bin`
to the base directory of a FAT formatted USB drive using DOS
partition scheme ,where XXXX is mx64, mx64_a0 or mx65 depending on
which device you have.
2. With the USB drive already inserted, power on the device. Boot time
will be longer than usual while Shmoo calibration takes place. A
different white/orange flashing pattern will eventually occur to
indicate device is now booting into OpenWrt initramfs stored on the
USB disk.
3. Ensuring Ethernet is plugged into a LAN port with IP set in the
192.168.1.0/24 subnet excluding 192.168.1.1, use SCP to copy the
sysupgrade file to 192.168.1.1:/tmp, eg:
`scp openwrt-bcm53xx-generic-meraki_XXXX-squashfs.sysupgrade.bin\
192.168.1.1:/tmp`
4. Connect by SSH to 192.168.1.1 and run sysupgrade:
`sysupgrade \
/tmp/openwrt-bcm53xx-generic-meraki_XXXX-squashfs.sysupgrade.bin`
5. OpenWrt should now be installed on the device.

Subject: [PATCH] bcm53xx: partition fixups for Meraki MX64/MX65
|
||||
|
||||
We need to enlarge the u-boot partition to add extra features like UBI
|
||||
booting. The shmoo and newly created env partitions can easily be moved
|
||||
to the nvram partition. This fixup allows u-boot to be enlarged to up to
|
||||
1MiB.

Subject: [PATCH] bcm53xx: dts: meraki-mx6x: add OpenWrt-specific LED aliases
|
||||
|
||||
Assign green power LED for "boot", "running", orange for "upgrade" and
|
||||
red for "failsafe" functions - the same as done for MR33 and MR74.
