MT6261¶

Similar to MT6260 but with less RAM so that loading with fernly must be changed slightly.

There is initial support for this chipset in fernly here: https://github.com/isogashii/fernly/tree/fernly6261

Bootloader works identically to MT6260, same baud rate, config block is at 0x80000000 and chip id is at 0x80000008
