Andreas Färber ed54838ea6 flash/nor/xmc4xxx: Loosen checks for XMC4500
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.

Jeff Ciesielski 33b048d456 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.

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.

Matthias Welwarsky 411ca773f0 armv7a: re-read ttb information if ttbcr changes
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.

Andrew Ruder afb083625c 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.

GDB exerpt:

Breakpoint 1, 0x000040b6 in Reset_Handler ()

Hardware assisted breakpoint 2 at 0x40f8

Andrew Ruder 9413a7a814 rtos: turn stack alignment into a function pointer
Some targets (Cortex M) require more complicated calculations for
turning the stored stack pointer back into a process stack pointer.
For example, the Cortex M stores a bit in the auto-stacked xPSR
indicating that alignment had to be performed and an additional 4
byte padding is present before the exception stacking.  This change
only sets up the framework for Cortex-M unstacking and does not
add Cortex-M support.

Note: this also fixes the alignment calculation nearly addressed by
change #2301 entitled rtos/rtos.c: fix stack alignment calculation.
Updated calculation is in rtos_generic_stack_align.
