Label	Component	Part	Markings	Notes
Red	NAND flash	Toshiba THGBX2G7D2JLA01 128 Gb (16 GB)
Orange	Touchscreen controller	Texas Instruments 343S0538
Yellow			Apple 338S1146
Green	SoC/CPU	S5L8740	339S0193	8740 per IMG1. Guessing based on similar package to N6G SoC/CPU. Also has the most diffpairs running to/from it (from delayered PCB).

Teardowns:

Cortex A5 according to CP15:

ID code: 0x410fc050
  Implementer: ARM
  Variant: 0x0
  Architecture: See CPUID
  Part number: c05, Revision: 0

There is no big debug table with all clock gates in N7G RetailOS, so the following has been written out by hand:

Address	Bits (clear to power on)	Meaning	Source
0x3C50006C	0x2000	'SPI power'	WTF DevicePowerManagement.dll
0x3C50004C	0x4	'SPI power'	WTF DevicePowerManagement.dll
0x3C50004c	0x1f800020	Timer	WTF IpodSec.dll
0x3C500058	0x60	Timer	WTF IpodSec.dll
0x3c50006c	0xc0007f	Timer	WTF IpodSec.dll
