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".
