Making Picostation m2HP work

[Luiz Otavio O Souza]

Hi Hiren,

I've looked at ubnt firmwares and there are a few identifiers that i can
gather:

All the 'M' series (rockets, airgrids and many others) uses the same
firmware identifier: 'XM'.

The b/g 2Ghz radios uses the 'XS2' identifier and the 5Ghz models uses the
'XS5'.

The original PicoStation2 HP firmware has the following identifier:

$ hexdump -C PicoStation2HP-v4.0.3.build5058.bin
00000000  55 42 4e 54 58 53 32 2e  61 72 32 33 31 36 2e 76
 |UBNTXS2.ar2316.v|
00000010  34 2e 30 2e 33 2e 35 30  35 38 2e 31 33 30 33 32
 |4.0.3.5058.13032|
00000020  38 2e 31 30 35 34 00 00  00 00 00 00 00 00 00 00
 |8.1054..........|
00000030  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00

Can you try to build an image using 'XS2' as the board type and
'XS2.ar2316.FreeBSD' as the version string ?

If you create a correct image the update process will succeed even if the
compression is wrong (the loader will fail to boot, but that is ok, we can
hopefully fix the image later).

The kernel load address and entry point set by mkfwimage for the XS2 board
is different from what we expect:

                .name           =       "XS2",
                .kern_start     =       0xbfc30000,
                .kern_memstart  =       0x80041000,
                .kern_entry     =       0x80041000,
                .firmware_max_length=   0x00390000,

So you may need to adjust your kernel or the settings on mkfwimage for this
firmware template.
