[LEDE-DEV] [RFC] Need help to support CPU frequency setting on Mikrotik RB devices

[Nishant Sharma]

Hi,

Here is the data from RB951Ui-2HnD running OWRT 15.05.1 (custom compiled).

I guess, this is accessible over UART. But I do not have access to UART 
port as devices are in the field

> 4. if possible, for various cpu frequency settings (ideally for all of them), the output of `dmesg | grep Clocks; hexdump -C /dev/mtdblockN` where mtdblockN is the soft_config partition. Please provide this output at least once, even if there’s no frequency setting.

[    0.000000] Clocks: CPU:600.000MHz, DDR:400.000MHz, AHB:400.000MHz, 
Ref:25.000MHz

I can see /dev/mtdblock{0,1,2}.

Kernel is on mtdblock1 and filesystem on mtdblock2. Is that the 
mtdblock0 whose hexdump is required? It is going to be a big one. Please 
suggest how to send it across.

> 5. Finally, which frequency setting is the factory default one

No idea on this one. Sorry.
