switch to new memory partitioning model: 'prexos' loads at 0; boot stack and boot_info resides below 0x00100000. bootldr starts at 0 and loads kernel and friends upwards from 0x00100000 (1M); then, bootldr rewrites himself with first 15 words of kernel .text and jumps into actual loaded kernel (0x00100000 + entry). Kernel assigns new SVC, SYS and IRQ stacks - all below BOOT_INFO (1M - BOOT_INFO_SIZE). This means that zero MB holds vectors trampolines into higher addresses, boot_info and all kernel stacks.

first steps to let Prex kernel compile and run on arm-cats platform. clocks and interrupts subsystems are stubs, but kernel diagnostics messages work (using serial port 0). kernel boots and panics in thread_init, but at least it boots and prints something! it's far more easy and fun to hack code which compiles (: still more work on the road.
