Each Cortex-R5F processor contains exclusive two 64 KB memory banks on the ATCM and BTCM ports, for a total of 128 KB of memory. In lockstep mode, both 128KB memory is accessible to the cluster. As per ZynqMP Ultrascale+ Technical Reference Manual UG1085, following is address space of TCM memory. The bindings in this patch series introduces properties to accommodate following address space with address translation between Linux and Cortex-R5 views. | | | | | --- | --- | --- | | *Mode* | *R5 View* | *Linux view* | Notes | | *Split Mode* | *start addr*| *start addr* | | | R5_0 ATCM (64 KB) | 0x0000_0000 | 0xFFE0_0000 | | | R5_0 BTCM (64 KB) | 0x0002_0000 | 0xFFE2_0000 | | | R5_1 ATCM (64 KB) | 0x0000_0000 | 0xFFE9_0000 | alias of 0xFFE1_0000 | | R5_1 BTCM (64 KB) | 0x0002_0000 | 0xFFEB_0000 | alias of 0xFFE3_0000 | | ___ | ___ | ___ | | | *Lockstep Mode* | | | | | R5_0 ATCM (128 KB) | 0x0000_0000 | 0xFFE0_0000 | | | R5_0 BTCM (128 KB) | 0x0002_0000 | 0xFFE2_0000 | | References: UG1085 TCM address space: https://docs.xilinx.com/r/en-US/ug1085-zynq-ultrascale-trm/Tightly-Coupled-Memory-Address-Map Changes in v5: - maintain Rob's Ack on bindings patch as no changes in bindings - split previous patch into multiple patches - Use pm domain framework to turn on/off TCM - Add support of parsing TCM information from device-tree - maintain backward compatibility with previous bindings without TCM information available in device-tree This patch series depends on following pending patch: https://lore.kernel.org/all/20230925172648.2339048-1-tanmay.shah@amd.com/ This patch series continues previous effort to upstream ZynqMP TCM bindings: Previous v4 version link: https://lore.kernel.org/all/20230829181900.2561194-1-tanmay.shah@amd.com/ Previous v3 version link: https://lore.kernel.org/all/1689964908-22371-1-git-send-email-radhey.shyam.pandey@amd.com/ Radhey Shyam Pandey (1): dt-bindings: remoteproc: add Tightly Coupled Memory (TCM) bindings Tanmay Shah (3): dts: zynqmp: add properties for TCM in remoteproc remoteproc: zynqmp: add pm domains support remoteproc: zynqmp: parse TCM from device tree .../remoteproc/xlnx,zynqmp-r5fss.yaml | 131 ++++++- arch/arm64/boot/dts/xilinx/zynqmp.dtsi | 28 +- drivers/remoteproc/xlnx_r5_remoteproc.c | 346 ++++++++++++++++-- 3 files changed, 454 insertions(+), 51 deletions(-) base-commit: 1a93ced18d7b81be39beba26b1c168ef21c8d0ad prerequisite-patch-id: fe44cda02ab56ead54bea998952f27c8b7fc5ff0
