- Adjust free memory to kernel window, as well for the lower as the upper limit. - Log more detailed boot message to help porting. Signed-off-by: Axel Heider <[email protected]>

Handling memory based on physical addresses during boot is more intuitive and issues are easier to debug. This also requires much fewer conversions between region_t and p_region_t. Signed-off-by: Axel Heider <[email protected]>

Creating the untypeds is the place in the boot process where the switch from plain physical addresses to addressing physical memory via the kernel window happens. Passing physical region creates a single place of control, to check what can be addressed and what not. The region (or a part of) it could be outside the kernel window, so it cannot be accessed. Ensure to never generate a pptr outside of that window. Signed-off-by: Axel Heider <[email protected]>
- pass phys regions to arch_init_freemem() - make reserve_region() publicly available, make it smarter to insert or merge new regions, make it take physical regions. - remove 'reserved' and 'resv_count' from 'ndks_boot_t' and declare it a internal variable of the generic boot code.
