- Created driver framework with probe/init lifecycle. Drivers register via REGISTER_DRIVER macro which places pointers in a .drivers linker section. - During boot, init_drivers() iterates the section, probes each driver (checking if hardware is present), and initializes those that respond OK. - Added .drivers section to linker.ld with __drivers_start/__drivers_end symbols for iteration. - Also added .rodata.* pattern to the .rodata section for string literals placed in sub-sections by the compiler. - No drivers are registered yet; the VGA driver will be the first. Tested: boots cleanly with driver scan completing (0 registered, 0 loaded).
