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.

then they do one entry of r4 base + 48 (gRadioTOCCal2_24MHz_c[0])

0x80009000      
0x80050100

then they do 11 entries in cal3  and reg replacment  (first two have delays)

0x402b8c <gRadioTOCCal3_c>:     0x80009400      0x00020017      0x80009a04      0x8185a0a4
0x402b9c <gRadioTOCCal3_c+16>:  0x80009a00      0x8c900025      0x00000000      0x00011194
0x402bac <gRadioTOCCal3_c+32>:  0x80009a00      0x8c900021      0x80009a00      0x8c900027
0x402bbc <gRadioTOCCal3_c+48>:  0x00000000      0x00011194      0x80009a00      0x8c90002b
0x402bcc <gRadioTOCCal3_c+64>:  0x80009a00      0x8c90002f      0x00000000      0x00011194
0x402bdc <gRadioTOCCal3_c+80>:  0x80009a00      0x8c900000      

then 4 entries from r5+24 (buffer_radio_init and cal5)

0x80009400      0x00000017
0x405230 <gRadioTOCCal5+8>:     0x8000a050      0x00000000      0x8000a054      0x00000000
0x405240 <gRadioTOCCal5+24>:    0x80003048      0x00000f00

then 43 entries from r4+152 (reg replacement)

then flash init. (hrmm.. this might be important)

then flyback init.

then maybe buckbypass sequence... 4 entries from r4+16

0x402b64 <gBuckByPass_c>:       0x80003000      0x00000018      0x80003048      0x00000f04

RadioInit is (roughly):

    SMAC_InitFromMemory(gRadioTOCCal1,40);
    SMAC_InitFromMemeory(gRadioTOCCal2_24MHz_c,8);
    SMAC_InitFromMemeory(gRadioTOCCal3,88);
    SMAC_InitFromMemeory(gRadioTOCCal5,32);
    SMAC_InitFromMemeory(gRadioInit_RegReplacement_c,344);
    SMAC_InitFromFlash(0x1F000);
    SMAC_InitFlybackSettings();
    /* then they check stuff in ram_init_val */
    /* getting a dump of that now */
