* bcm53xx: backport early DT patches queued for 5.16Rafał Miłecki2021-09-2312-4/+642

* bcm53xx: drop DTS based workaround for serial support in procdRafał Miłecki2021-09-161-116/+0
| | | | | | | | | Specifying serial in bootargs is not needed since the commit ffeb37047e85 ("procd: update to git HEAD"). It's thanks to the procd commit 2cfc26f8456a ("inittab: detect active console from kernel if no console= specified"). Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

* bcm53xx: fix kmod-i2c-bcm-iproc for kernel 5.10Rafał Miłecki2021-08-311-1/+3
| | | | | | | | | | | | | | | | | | | | | I2C_BCM_IPROC selects I2C_SLAVE which in turn makes two new symbols available: I2C_SLAVE_EEPROM and I2C_SLAVE_TESTUNIT. That was causing: I2C support (I2C) [M/n/y/?] m Enable compatibility bits for old user-space (I2C_COMPAT) [N/y/?] n I2C device interface (I2C_CHARDEV) [M/n/?] m I2C bus multiplexing support (I2C_MUX) [N/m/?] n Autoselect pertinent helper modules (I2C_HELPER_AUTO) [N/y/?] n SMBus-specific protocols (I2C_SMBUS) [N/m/?] n I2C/SMBus Test Stub (I2C_STUB) [N/m/?] n I2C slave support (I2C_SLAVE) [Y/?] y I2C eeprom slave driver (I2C_SLAVE_EEPROM) [N/m/?] n I2C eeprom testunit driver (I2C_SLAVE_TESTUNIT) [N/m/?] (NEW) Ideally I2C_SLAVE should probably be packaged as kmod-i2c-slabe. For now just modify kmod-i2c-bcm-iproc to fix kernel compilation. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

* bcm53xx: backport first 5.13 DTS changesRafał Miłecki2021-03-143-1/+476

* bcm53xx: initialize NVRAM from NVMEM driverRafał Miłecki2021-03-122-0/+92
| | | | | | | | | | | NVRAM access may be needed early in boot process. Reading it using mtd happens quite late in the init process. Add NVRAM initialization to the NVMEM driver which comes up early and depends on IO mapping only. This is required by Linksys devices which use NVRAM content for proper partitioning (detecting current firmware partition). Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
* bcm53xx: backport NVMEM NVRAM driverRafał Miłecki2021-03-103-0/+181

* treewide: remove execute bit and shebang from board.d filesAdrian Schmutzler2021-03-062-2/+0
| | | | | | | | | | | | | | | | So far, board.d files were having execute bit set and contained a shebang. However, they are just sourced in board_detect, with an apparantly unnecessary check for execute permission beforehand. Replace this check by one for existance and make the board.d files "normal" files, as would be expected in /etc anyway. Note: This removes an apparantly unused '#!/bin/sh /etc/rc.common' in target/linux/bcm47xx/base-files/etc/board.d/01_network Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* treewide: rename IMAGE_PREFIX/IMAGE_NAME to DEVICE_IMG_*Adrian Schmutzler2021-02-251-1/+1
| | | | | | | | | | | | | | We so far had two variables IMG_PREFIX and IMAGE_PREFIX with different content. Since these names are obviously quite confusing, this patch renames the latter to DEVICE_IMG_PREFIX, as it's a device-dependent variable, while IMG_PREFIX is only (sub)target-dependent. For consistency, also rename IMAGE_NAME to DEVICE_IMG_NAME, as that's a device-dependent variable as well.

The Serial setting is 115200-8-N-1. The board has a populated right angle 1x4 0.1" pinheader. The pinout is: VCC, RX, TX, GND. (Use a multimeter) Flashing needs a serial adaptor (due to the lack of a working dropbear on the original firmware). This flashing procedure for the MR32 was tested with firmware: "r23-149867:150252-aacharya". 0. Create a seperate Ethernet LAN which does not have access to the internet. Ideally use 192.168.1.2 for your PC. Make sure to reserve 192.168.1.1 it will be used later on by the OpenWrt firmware. The original Meraki firmware will likely try to setup the network via DHCP Discovery, so make sure your PC is running a DHCP-Server (i.e.: dnsmasq) '# dnsmasq -i eth# -F 192.168.1.5,192.168.1.50 Furthermore, the PC needs a supported ssh/http/ftp server in order to retrieve the initramfs + dtb file 1. Disassemble the MR32 device by removing all screws (4 screws are located under the 4 rubber feets!) and prying open the plastic covers without breaking the plastic retention clips. Once inside, remove all the screws on the outer metal shielding to get to the PCB. It's not necessary to remove the antennas! 2. Connect the serial cable to the serial header. 3. Partially reassemble the outer metal shielding to ensure that the SoC has a proper heat sink. 4. Connect the Ethernet patch cable to the device and the power cable. 5. Wait for the device to boot and enter the root shell. (rooting is not discussed in detail here please refer to Chris Blake - "pwning the meraki mr18" blog post: <https://servernetworktech.com/2016/02/pwning-the-meraki-mr18/> (The same method works with the MR32's r23-149867:150252-aacharya) Wait for the MR32 to enter the "<Meraki>" prompt and enter: <Meraki> odm serial_num read (Verify that it matches what's on the S/N Sticker on the back!) <Meraki> odm serial_num write Q2XX-XXXX-XXXV <Meraki> odm serial_num read (Verify that the S/N has changed - and the LED start to flash) now to flash the firmware: <Meraki> odm firmware part.safe "http://192.168.1.2/mr32-initramfs.bin" Once OpenWrt booted use sysupgrade to permanently install OpenWrt. To do this: Download the latest sysupgrade.bin file for the MR32 to the device and use sysupgrade *sysupgrade.bin to install it. WARNING: DO NOT DELETE the "storage" ubi volume! To flash later MR32 Firmwares like r25-201804051805-G885d6d78-dhow-rel requires in-circut-i2c tools to access the I2C EEPROM AT24C64 next to the SoC. The idea is pretty much the same as from Step 5 from above: Change the serial number to Q2XXXXXXXXXV (should be around 0x7c), then attach a serial cable, ethernet (but make sure the device can't reach the internet!) hit "s" (the small s!) during boot to enter the root-shell and add the following commands to the /storage/config there: serial_allow_odm true serial_access_enabled true serial_access_check false valid_config true and then hit exit to let it finish booting.

This patch also includes the portion of the bcm53xx kernel patch refreshes as the hunks in 302-ARM-dts-BCM5301X-Update-Northstar-pinctrl-binding.patch moved slightly due to the added nodes.
