Lephe	1c7b1350b4	general cleanup of the kernel ... * Removed .pretext sections since the TLB is now entirely dynamic; left only .text.entry for the start symbol. * Reworked the main files of src/core to move the INTC to its own driver and let the kernel handle only VBR space and CPU (now: VBR & CPUOPM). * Moved src/core/gint.c to src/core/kernel.c and centralized all driver loops that save or restore context for more robustness. This leaves the callbacks of cpu_setVBR() (formerly gint_setvbr()) pretty short. * Coalesced gint_switch_out() and gint_switch_in() into a single function callback for cpu_setVBR(). * Added an abstraction of interrupt signals as an enumerated value so that drivers no longer hardcode the IPR and IMR numbers and bits, sometimes even with isSH3() due to differences in the SH7705. * Changed the interrupt blocking method in cpu_setVBR() from SR.BL=1 to SR.IMASK=15 so that TLB misses are still handled. This removes the need for callback functions to be GMAPPED. * Moved gint_osmenu() and its utilities to a new file src/core/osmenu.c.	2020-06-20 17:18:51 +02:00
