flash: New driver for XMC4xxx microcontroller family
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.
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...)

target: cortex_a: do not create new register cache every reset
Commit 68101e67ac16bdead3bd6d48cbe0a2bfd63aac02 introduced a
regression which resulted for ever-growing registers list (as output
by "reg" command), its contents were doubled every reset (actually,
every examination).
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.

rtos: handle STKALIGN adjustments on cortex m
In the case that the STKALIGN bit is set on Cortex M processors, on
entry to an exception - the processor can store an additional 4 bytes
of padding before regular stacking to achieve 8-byte alignment on
exception entry. In the case that this padding is present, the
processor will set bit (1 << 9) in the stacked xPSR register. Use the
new calculate_process_stack callback to take into account the xPSR
register and use it on the standard Cortex_M3 stacking.
Note: Change #2301 had some misinformation regarding the padding. On
Cortex-M the padding is stored BEFORE stacking so xPSR is always
available at a fixed offset.
Tested on a Cortex-M0+ (Atmel SAMR21) board which has STKALIGN fixed
to a '1' such that this alignment always occurs on non-aligned stacks.
Behavior of xPSR verified via the (bad-sorry) assembly program below by
setting a breakpoint on the SVC_Handler symbol. The first time
SVC_Handler is triggered the stack was 0x20000ff8, the second time
SVC_Handler is triggered the stack was 0x20000ffc. Note that in both
cases the interrupt handler gets 0x20000fd8 for a stack pointer.

To get high-speed JTAG data transfers, I'm using a very long shift

latency due to the common USB adapter transfers considerably. In order
to submit those long DRSCAN commands to OpenOCD over the TCL/TCL

v3:

fails.
Changes in v2 of this patch:
The line buffer is allocated dynamically to avoid an OpenOCD memory
overhead if the large buffers are not used. The buffer starts at 4K and
increases exponentially up to 1M, and then linearly in 1M increments up
to 4M.
