16000kHz is only safe after PLLs have been locked
properly. Until that's done (with reset init), we
can only safely run at 1000kHz.

Added interface config file for the FTDI FT232H based UM232H module.
This should work with UM232H-B too, an even cheaper module, but
that has not been tested.

According to Infineon, XMC4500 EES AA13 with date codes before GE212 -
as seen on an XMC4500 General App Kit - had a zero SCU_IDCHIP register.
Handle this by extending our checks to not error out on zero SCU_IDCHIP
and by printing a useful info string in that case.

This is a complete flash driver for the Infineon XMC4xxx family of
microcontrollers, based on the TMS570 driver by Andrey Yurovsky.
The driver attempts to discover the particular variant of MCU via a
combination of the SCU register (to determine if this is indeed an
XMC4xxx part) and the FLASH0_ID register (to determine the variant).
If this fails, the driver will not load.
The driver has been added to the README and documentation.
Tests:
* Hardware: XMC4500 (XMC4500_relax), XMC4200 (XMC4200 enterprise)
* SWD + JTAG
* Binary: 144k, 1M
Note:
* Flash protect only partly tested. These parts only allow the flash
protection registers (UCB) to be written 4 times total, and my devkits
have run out of uses (more on the way)
Future Work:
* User 1/2(permalock) locking support via custom command
* In-memory flash loader bootstrap (flashing is rather slow...)

This is a driver for the Atmel Cortex-M7 SAMV, SAMS, and SAME.
I started with the at91sam4.c driver and then restructured it
significantly to try to simplify it and limit the functionality
to just a flash driver, as well as to comply with the style guide.

If ttbcr is changed after the debugger has examined a target for the
first time, address translations may fail. This problem does not show up
with Linux because it doesn't use ttbr1, but it shows with other OS that
use this feature. If the debugger connects to the target while it's in
u-boot, all address translations will fail after the OS has booted and
the target can not be debugged.
This patch reads the ttbcr in armv7a_mmu_translate_va() and compares it
a cached value. If a difference is detected, armv7a_read_ttbcr() is called
to re-parse the ttb configuration and update the cache.
