Remove weird LDSCRIPT that isn't necessary now.
...
Change .bin generation to include only ROM-able sections.
TODO: Is there a better way to do the objcopy? It'd be great to put everything in the "rom" region into the .bin, instead of having to list out -j section for each of the sections that go to ROM.

Now that RxVGA gain control is working correctly, gain needs to be backed WAAAY off to get a usable capture in a fairly noisy 2.4GHz environment.

Fixed incorrect field with for MAX2837 VGAgain_SPI_EN field. For boards that have no B7:B1 connections, this could prove extra problematic...and for boards that do, but aren't driving those pins from the LPC.

Consolidated two "deep" SGPIO configuration functions into one, qualified by transceiver mode (RX or TX). 95-ish % of the code was common.

Moved transceiver_mode_t to hackrf_core.h.

Changed transceiver_mode to volatile, since it's liable to be accessed at interrupt time.

Reworked USB code to pump SGPIO with an interrupt.
...
Relocated USB buffers to be split across two AHB memory regions, so that USB endpoint priming doesn't choke SGPIO transfers.
Added code to configure 2.4GHz front-end.
Changed USB and SGPIO priority levels (probably unnecessary because sample corruption was due to USB priming bursts).

Added fault handler header file, where I've defined the Cortex-M3/M4 SCB using a struct instead of a slew of #defines. This deviates from the libopencm3 method, but is superior in other ways. So, there you go. It's not in libopencm3, it's here.
...
Added example (er, "reminder") code comment about registers to look at when debugging a Hard Fault.
