Entries in ram are processed by SMACinitfrommemory and executeentry
(which does the work). I suspect that these entries are loaded in from
the rom from the rom_data_init call in the beginning stub. For now
we'll do the simple thing of performing the actions they do, but for
real it would be better to load out from ROM and execute the entries
in a similar way. That way, if the cal data changes in the ROM, our
code should still work.
When radioinit first starts it seems to do checks for a 24MHZ clock
and if the buck should be enabled. Assuming 24MHZ and no buck the next
things it does is 5 entries in cal1 (40 bytes, 4 bytes per word, = 10
words, 2 words per entry = 5 entrys)
0x80003048
0x00000f78
0x8000304c
0x00607707
the next entry is zero addr with val 0x000161a8... this is a delay
entry. Loop here 0x000161a8 times. then return.
0x00000000
0x000161a8
Then two more memory stuffs:
0x8000a050
0x0000047b
0x8000a054
0x0000007b
then it seems like the emulator dies on the stack munging they do at
the end of InitFromMemory... but I think I've decoded the entry
enough to figure out the rest.
but it looks like they then redo the first entry in cal1
0x80003048
0x00000f78
then they do 11 entries in cal3 (need dump)
then 4 entries from r5+24 (need to check what r5 has... 0x4051e4
should dump this)
then 44 regreplacment entries
then flash init. (hrmm.. this might be important)
then flyback init.
then some other stuff. (need to check this out closley)
