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
