efc454035c Move all code paths touched by NMI to IRAM 
Prerequisite for calling Cache_Read_Disable() for OTA updates.

Massive thanks due to @foogod and their xtobjdis tool, creating the call
graph of where the wDev_ProcessFiq touched (including in newlib, etc.)
would have otherwise been very painful:

ed7ba52c9a Add exception vectors & low-level handlers 
At the moment these are almost bit-for-bit copies of the vector
behaviour in the RTOS SDK, but hopefully that will start to change.

Progress towards #2

a566a51c09 Use linker scripts rather than libcirom/objcopy tricks to arrange 
IRAM/IROM sections.

esp-open-rtos compiled code: .text goes into irom by default, symbols
explicitly marked with IRAM attribute go into iram.

SDK code: .text goes into iram by default, symbols marked with
ICACHE_FLASH_ATTR go into irom.

libgcc functions also go into iram by default.

49268a33e1 Link against newlib from esp-open-sdk's libcirom, replace FreeRTOS heap management. 
Compiles and runs, expects xtensa lock.c patch in newlib (will still run
otherwise but malloc/free and other functions will be non-memory-safe...)

1b0124cf05 Timer FRC1 & FRC2 registers 
Mostly determined from reverse engineering and poking around.

Includes first "experiments" program with random bits and pieces for
poking at registers, may be useful to keep in source control but not
useful for writing actual programs.

0dbb6d31a5 Add IRAM attribute for IRAM loaded symbols, add to common FreeRTOS functions 
Closes #7.

It'd be nice to change the linker script so .text is always linked to
IROM instead of needing to objcopy each compiled file. The sticking
point for this is libgcc & libhal, which have symbols in .text that need
to be loaded to IRAM.
