[PATCH 02/13] dt-bindings: thead: add a vlen register length property

2024-06-09 Thread Charlie Jenkins
Add a property analogous to the vlenb CSR so that software can detect the vector length of each CPU prior to it being brought online. Currently software has to assume that the vector length read from the boot CPU applies to all possible CPUs. On T-Head CPUs implementing pre-ratification vector, rea
