3934 5741 d 14 h jermar /trunk/kernel/ Improve the ns16550 driver.

- The driver support multiple instances.
- It still remembers the last registered IRQ in a global structure (cannot be
easily fixed now)
- Was converted to use PIO directly
 
3932 5741 d 15 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
 
3931 5741 d 15 h jermar /trunk/kernel/genarch/ Improve the i8042 kernel driver (phase I).

- Convert the code to be instance-aware
- Still using hardcoded initialization from legacy IO address
- Use elegant i8042 register map for PIO
 
3930 5741 d 15 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3929 5741 d 15 h jermar /trunk/kernel/arch/ Introduce ioport8_t, ioport16_t and ioport32_t. These types are to be used with
pio_read_n() and pio_write_n() functions. This breaks everything.
 
3928 5741 d 18 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3927 5741 d 18 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3922 5743 d 15 h decky /trunk/ make arch_pre_main optional, don't force any specific prototype
simplify boot process
mips32: detect number of configured CPUs in msim
 
3920 5743 d 15 h decky /trunk/kernel/generic/include/ add min3 and max3 macros  
3919 5743 d 15 h decky /trunk/kernel/generic/include/ cstyle  
3918 5743 d 15 h decky /trunk/kernel/ avoid ugly ifdefs in fpu1 test  
3917 5743 d 16 h decky /trunk/ remove non-standard define  
3913 5743 d 23 h decky /trunk/ mips32: basic SMP support  
3910 5744 d 13 h decky /trunk/kernel/arch/mips32/ eliminate non-standard -D$(MACHINE)  
3908 5744 d 19 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3907 5745 d 3 h decky /trunk/kernel/ remove forgotten #ifdef arch  
3906 5745 d 14 h jermar /trunk/kernel/ IRQ handlers are using one superfluous argument and an unused elipsis.
On the other hand, IRQ claim functions would need to be passed the instance
argument.
 
3903 5745 d 22 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32 build for Pentium 3 systems.  
3902 5745 d 22 h jermar /trunk/kernel/ Introduce a more platform-neutral name for programmed I/O.

The new API looks like pio_read_n() or pio_write_n(), where n is 8, 16 or 32.
The old API (i.e. inb(), inw(), inl(), outb() outw(), outl()) may have made
some people think that the interface is only to be used with the separate I/O
space. That's not the case. This API is to be implemented on all platforms
so that we can finally have really generic kernel device drivers.
 
3900 5746 d 0 h jermar /trunk/ Get rid of CONFIG_NS16550_INTERRUPT_DRIVEN and CONFIG_I8042_INTERRUPT_DRIVEN.
