From: Radhey Shyam Pandey <radhey.shyam.pandey@amd.com> Introduce bindings for TCM memory address space on AMD-xilinx Zynq UltraScale+ platform. It will help in defining TCM in device-tree and make it's access platform agnostic and data-driven. Tightly-coupled memories(TCMs) are low-latency memory that provides predictable instruction execution and predictable data load/store timing. Each Cortex-R5F processor contains two 64-bit wide 64 KB memory banks on the ATCM and BTCM ports, for a total of 128 KB of memory. The TCM resources(reg, reg-names and power-domain) are documented for each TCM in the R5 node. The reg and reg-names are made as required properties as we don't want to hardcode TCM addresses for future platforms and for zu+ legacy implementation will ensure that the old dts w/o reg/reg-names works and stable ABI is maintained. It also extends the examples for TCM split and lockstep modes. Signed-off-by: Radhey Shyam Pandey <radhey.shyam.pandey@amd.com> Signed-off-by: Tanmay Shah <redacted> ---
I responded under my reviewed-tag, but to be clear, also here: This patch has is not ready. Please do not merge.
