[Qemu-devel] [PATCH v8 00/13] Add support for the ZynqMP Generic QSPI

[Francisco Iglesias <frasse.iglesias@gmail.com>]

Hi,

This patch series is an attempt to add support for the ZynqMP QSPI (consisting
of the Generic QSPI and the legacy QSPI) to the xlnx-zcu102 board and connect 
Numonyx n25q512a11 flashes to the QSPI. Also some functionality is added to
m25p80.

The series starts by adding support in m25p80 for continous read out of status
registers, SST flash READ ID commands, bank address register accesses, bulk
erase (0x60) and two Numonyx flashes (n25q512a11 and n25q512a13). Thereafter it
updates the striping behaviour to be bit big endiann in the Xilinx QSPI model
and adds support for RX discard, zero pumping according transfer register and 4
byte LQSPI addresses. Finally it adds support for the ZynqMP Generic QSPI and
adds the ZynqMP QSPI to the xlnx-zcu102 board.

Best regards,
Francisco Iglesias

Changelog:
v7 -> v8
  * Corrected commit messages in the patches 'xilinx_spips: Don't set TX FIFO
    UNDERFLOW at cmd done' and 'xilinx_spips: Move FlashCMD, XilinxQSPIPS and
    XilinxSPIPSClass'.
  * Changed a for loop and a variable decrease for improving readability in
    patch 'xilinx_spips: Update striping to be big-endian bit order'.

v6 -> v7
  * Moved data_read_loop into a vmstate subsection in patch 'm25p80: Add support
    for continuous read out of RDSR and READ_FSR' for not breaking compatibility
    against older vmstate versions unless necessary.
  * Minor tweaks in patch 'xilinx_spips: Add support for the ZynqMP Generic
    QSPI'.

v5 -> v6
  * Added data_read_loop to vmstate_m25p80 in patch 'm25p80: Add support for
    continuous read out of RDSR and READ_FSR'. Also removed acked-by lines in 
    the commit message because of this update.
  * Reworked patch 'xilinx_spips: Add support for the ZynqMP Generic QSPI'.
  * Tweaked commit messages 

v4 -> v5
  * Added newlines in patch 'xlnx-zcu102: Add support for the ZynqMP QSPI'

v3 -> v4
  * Corrected patch 'Add support for SST READ ID 0x90/0xAB commands'
  * Corrected patch 'Add support Add support for BRRD/BRWR and BULK_ERASE'
  * Minor tweaks in the ZynqMP GQSPI patch for reducing the patch 

v2 -> v3
  * Tweaked commit messages 
  * Corrected patch 08 'Make tx/rx_data_bytes more generic and reusable'
  * Reworked the patch adding the ZynqMP GQSPI and splitted out another QSPI
    related change into an own patch 'Don't set TX FIFO UNDERFLOW at cmd done'
