0x08050000 DeleteConfigNANDSavefile
0x08060000 FormatConfig
0x08070000 This basically just returns result-code value 0x0, due to code this eventually executes being NOPed out.
0x08080000 This updates the config blocks for blkIDs 0x0 and 0x20000. In certain cases this may call the code for FormatConfig.
0x08090000 This updates the config block for blkID 0x60000.
0x080A0000 ResetAnalogStickCalibrationParam? This updates the config block for blkID 0x00040001.

Config NVRAM service "cfg:nor"

Command Header Description
0x00010040 Initialize
0x00020000 Shutdown
0x00030040 (u8 flag) Writes the input flag to state. Uses SPI service command EnableSpiBus.
0x00040000 Writes the u8 from the state written by 0x00030040 to cmdreply[2].
0x00050082 ReadData
0x00060082 WriteData
0x00070000 This just uses the WREN command.
0x00080000 This just uses the WRDI command.
0x00090000 ReadIdentification
0x000A0000 This waits for the WIP bit in the status register to clear(wait for writing to finish).
0x000B0000 This waits for the WEL bit in the status register to become set(write enabled).
0x000C0000 This writes the value of the WIP bit in the status register to u8 cmdreply[2].
0x000D0000 This writes the value of the WIP bit in the status register to u8 cmdreply[2].
0x000E0000 ReadStatusRegister
0x000F0082 ReadDataOther
0x00100082 WriteDataOther
0x00110040 (u32 offset) Uses command WREN then waits for WEL to become enabled. Sends command 0xDB to SPI followed by the specified flash offset.
0x00120040 (u32 offset) Identical to 0x00110040 except this uses SPI-command 0xD8 instead("block erase").
0x00130000 This uses SPI command 0xB9 for "Deep power down".
0x00140000 This uses SPI command 0xAB for "Release from deep power down".

This is an interface for the "SPI::NOR" service, for accessing the Wifi NVRAM/SPI Flash.
