Use of the RISC-V instruction set only in a Open-source FPGA design (license question)
I have started to create a VHDL design for new architecture. Now I'm thinking about the used instruction set. Could create an own encoding of the used machine code, but must create a C compiler for it or port the architecture to an existing compiler like GCC. Also must write an assembler, if I use an own instruction set.
What are the license requirements for me as developer, when I want use any specific parts of the RISC-V instruction set only? Would also to add some specific processor control registers and a modified base architecture. Might be security by obscurity, but control registers where I can setup the end of the stack and the size in privileged mode. Also two types of the stack. Return address and data, both separately as example.
BTW: The project is currently for the purpose of education only. Without interest from me to sell this maybe exotic (not RISC-V itself, but my modifications) architecture.

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
Telegram hopes to raise $1bn with a convertible bond private placement
The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.
