Using SVF for Nordic firmware update

Yes, the interface is described in the nRF51 reference manual. It's a standard SWD interface, but enabling the interface is proprietary and described in the reference manual.
yes, both softdevice and application firmware. It's also possible to update the bootloader itself if needed.

Thank you for information!

Is nRF51822 flash ROM programming SWD protocol open, so we could implement it in our management processor firmware?
Using this bootloader, is it possible to update firmware when major firmware version number is changing, using only UART interface?

Yes, you can connect to the SWD interface on the nRF51822 and program it through those pins as if you had a normal programmer connected to it.
I'm not familiar with the SVF format, but as long as it is hex structure and programmed as any other SWD programmer, it should be fine.

We have a bootloader available that will enable you to upload new firmware across Bluetooth low energy or through UART. This might be a good alternative for you. Have a look in the nRF51-SDK DFU folder.
