I'll give it a try and will let you know.
Actually I managed to go on by picking required files and building the extracted project with my own Makefile. This way I got LCD working and rewritten it. So now I have my own code for GPIO,FSMC,USART and LCD. Next step would be USB and ETH.
It turns out that:
1. STM32 is not that complex. I see no problem for me to write my own code and do not use Standard Peripheral Library (SPL) at all. At leas one benefit of it is that I know exactly how HW modules are working and what features I can get from HW. For instance studding FSMC and LCD code let's me easy pass from demo board LCD with 16 bit parallel ILI9325 to 8-bit parallel ILI9341.
2. SPL is ugly. It is written BAAAAAD. It is not efficient and not flexible. All you can do with it is to use it as reference.
According to English in comments code is written by first grade student(s) in India or China.
3. STM32 documentation is not good as well, compared to the documentation level I got used with Atmel. There is a lot of things that are not clear from specs and the only way to guess how it exactly works is to look at source code or try it and check with scope. Hope that chip design itself is better.
But overall I like the STM32 CPU and will go on with it.
