[Qemu-devel] [PATCH 00/12] Add support for the ZynqMP Generic QSPI

[Qemu-devel] [PATCH 00/12] Add support for the ZynqMP Generic QSPI

[Francisco Iglesias]

Hi,

This patch 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, endiannes
configuration of TX/RX registers, zero pumping according tranfer 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
