Next Generation Xilinx Zynq SoC
v2 cover Next Generation Xilinx Zynq SoC
Hi Peter and all,
Xilinx's next gen SoC has been announced. This series adds a SoC and board.
Series start with addition of ARM cortex A53 support (P1 and P2). The Soc skeleton is then added with GIC, EMACs and UARTs are added. The pre-existing models for GEM and UART are not SoC friendly (no visible state struct), so those are refactored for SoC.
Create a model of the EP108 board. Currently this doesn't have any EP108 specific features but is a usable board exposing the user visible features of the raw SoC.
changed since v1:
Addressed Alistair review (individual changes on resp. patches) Changed board name to EP108
Changed naming scheme to "zynqmp" / "ZYNQMP" (Michal review)
Regards,
Peter

PATCH v2 1/15 target-arm: cpu64: Factor out ARM cortex init
In preparation for support for Cortex a53. Use "axx" to describe the shareable features. Some of the CP15 registers (such as ACTLR) are specific to implementation, but we currently just RAZ them so continue with that as the policy for all cortex A processors under a shared definition.
The cache sizes and geometeries, the L1 I-cache policy and the physical address range differ between A53 and A57 so those particulars are left as A57 specific. The rest are moved to the generalisation.

In reply to Peter CrosthwaiteSimilar to a53, but with different L1 I cache policy, phys addr size and different cache geometries. The cache sizes is implementation configurable, but use these values (from Xilinx MPSoC) as a default until cache size configurability is added.

Removing the error_abort doesn't help either, then it just seg faults further on.

./aarch64-softmmu/qemu-system-aarch64 -M xlnx-ep108I get the following error (associated with this line):
qemu-system-aarch64: attempt to add duplicate property 'cpu' to
object (type 'xlnx,zynqmp')
Aborted (core dumped)
Fixed. I'm still confused as to how I didn't get this in V1.

Removing the
error_abortdoesn't help either, then it just seg faults further on.Thanks,

PATCH v2 6/15 net: cadence_gem: Clean up variable names
In reply to Peter CrosthwaiteIn preparation for migrating the state struct and type cast macro to a public header. The acronym "GEM" on it's own is not specific enough to be used in a more global namespace so preface with "cadence". Fix the capitalisation of "gem" in the state type while touching the typename. Also preface the GEM_MAXREG macro as this will need to migrate to public header.

PATCH v2 9/15 char: cadence_uart: Clean up variable names
In reply to Peter CrosthwaiteIn preparation for migrating the state struct and type cast macro to a public header. The acronym "UART" on it's own is not specific enough to be used in a more global namespace so preface with "cadence". Fix the capitalisation of "uart" in the state type while touching the typename. Preface macros used by the state struct itself with CADENCE_UART so they don't conflict in namespace either.
