Many changes there touch some irrelevant mechanisms. - Ive compiled kernel with microblaze target. To full build ldscript needs to be fitted. Linking objects passes. Fitting pieces together into kernel file not yet. What I am doing now: - instructions how code can be built for now - ldscript adjustments - first attempts in bootstrap field and memory initialization - of course midterm evaluation During next week I would like make: - plam of memory map - booting (not final version yet. Something which could load and run code in any way on target) - locore.S I am concern about way to include toolchain. I can either add it to ports tree or contrib in source tree. But there are parts with not BSD-compliant license (GPLv3). Temporally I prepared a script which builds a microblaze toolchain.
