[Xen-devel] [PATCH v12 01/10] x86/boot: implement early command line parser in C

2017-01-19 Thread Daniel Kiper
Current early command line parser implementation in assembler is very difficult to change to relocatable stuff using segment registers. This requires a lot of changes in very weird and fragile code. So, reimplement this functionality in C. This way code will be relocatable out of the box (without p
