Tarek BOCHKATI 0b7eca1769 flash/stm32h7x: add support of STM32H7Ax/H7Bx devices
this new device has the following features:
 - single core cortex-M7
 - 2MB flash - dual bank
    - page size 8k
    - write protection grouped by 4 sectors
    - write block size 128 bits (16 bytes)

the bit definition of FLASH_CR is different than STM32H74x,
that's why we introduced a helper to compute the FLASH_CR value

Tomas Vanek e7e681ac2b flash/nor/stm32l4x: fix minor errors in flash write/async algo
Fix comment of tested errors in asm src.

List all relevant errors in FLASH_ERROR mask: FLASH_PROGERR was missing
and any trial to re-program already programmed double word ended up
in the error bit held uncleared and flash write permanetly repeating
the error message until reset.

Lock the bank also after unsuccesfull write_block run.

Set async target algo block size to size of double word.

Remove warning in case of write_block success. In case of error
use LOG_ERROR instead of warning.

Tarek BOCHKATI 678fb4f60b target/stm32h7x: add support of dual core variant of STM32H7
STM32H7x7 and STM32H7x5 devices contains two cores : CM7 + CM4
The second core creation is only done when
  * DUAL_CORE variable is set to true
  * non HLA interface is used

A second check for the second core existence is done in cpu1 examine-end
Once the second core is detected it gets examined.

Furthermore, the script provides a configurable CTI usage in order to halt
the cores simultaneously.

Tested on Rev X and V devices.

PS: the indentation was a mix of spaces and tabs, all changed to tabs.

Tarek BOCHKATI 7ee618692f flash/nor/stm32h7x: use of wait queue flag instead of the busy flag
Based on RM0433.rev5 > Section 3.3.9 : Flash program operations:
  QW1/2: this bit indicates that a write, erase or option byte change
  operation is pending in the write queue or command queue buffer.
  It remains high until the write operation is complete.
  It supersedes the BSY1/2 status bit.

On this basis, stm32x_wait_status_busy is renamed accordingly to be
  'stm32x_wait_flash_op_queue'

Note : In this commit there is a fix of SR_ERROR_MASK value in flash loader algo
Note : This modification is mandatory for revision X, and backward compatible
  with old revisions

Tomas Vanek b941e2e727 flash/nor, contrib/loaders: add stm32 loaders Makefile and generated .inc
Flash loaders refactored to the new style - use generated .inc
instead of hexadecimal machine code in the flash driver source.
