Script for generating SVD and C-headers

[Yangff]

Hi, I create a simple script to generate SVD and headers for all peripherals under 0x44XXXXXX based on all currently knowledges.

I havn't try compile it and it may contain errors for both offset, naming and generated code.

SVD can be imported into ghidra to produce a little more readable code, although mask the real address might cause problem. Or maybe used for svd2rust. I only generated <peripheral> but you only need to merge it with original bl602 svd.

But, I cannot guarantte the correctness of these code..

It contains some research notes from This Documents.

And, mac_pl is from alios, based on my observation, it should be the same including the offset. While mac_core and ipc is from here.
and here.

Others are mainly my guess.

Beside that, it should be pretty simple to add more generate for markdown or other uses.

Usage

extarct related functions

This step allow you to isolate interested function that access certain addresses for you to analyse.

Place the ghidra decompiled C code into ./blobs/bl602_demo_wifi.ghidra.c, ensure that NO SVD is imported.
Make sure you have ctags installed.

./extract_funcs.sh | ./getfuncs.py [Intreasted Address, e.g. DAT_44c0] > somefile.c

And you can now open somefile.c to see the result.

Update it with your research and generate the result

Open manualext.py, modify it in a way you prefer and run it.

It's straightforward.

• Use Peripheral(peripheral('name', address, size)) to define a new peripheral.
• Use Reg(name, address) to define a reg
• Use Field(name, mask) to define a field where the bits of that field is zero in the mask
• Use FieldBit(name, bit, len=1) to define a field with lsb=bit and msb = bit+len-1
• Use Buf(name, beginaddress, endaddress, nBytes=4) to define an array at [beginaddress, endaddress], both side included. nBytes is the sizeof each item.
• Use GenSVD() to generate SVD for current peripheral.
• Use GenHeader to generate C header for cuurent peripheral.

Hi @Yangff
Really great job! Is this final commit, or you plan to add more things?

Also, I can give you an access to nutcracker repositories, so you can push things directly.

Thanks,

I'm still adding some extra symbols. Will replay when finish

it should contain all possible symbols for now, not sure if it's correct but I think it can merge now.

I will try replacing existed objects to get some lower level rewrite code. But I'm not sure what to do about higher level like 80211 or even IPs..

found some extra header in https://github.com/jixinintelligence/bl602-604/tree/37f2d7b36b4c2ba6f073029d351551c33f9610f3/components/bl602/bl602_wifi/plf/refip/src/driver/phy/bl602_phy_rf/reg and include them..

that should be all sources..

@Yangff thanks!
