kernel: oxpcie serial card support. ask to map in oxpcie i/o memory and support serial i/o for it in the kernel. set oxpcie=<address> in boot monitor (retrieve address using pci_debug=1 output). (no sanity checking is done on the address currently.) disabled by default. The change also contains some other minor cleanup (a new serial.h to set register info common to UART and the OXPCIe card, in-kernel memory mapping a little more structured and env_get() to get sysenv variables without knowing about the params_buffer). 2010-05-19 12:00:02 +02:00			`oxpcie.c \`

SMP - We boot APs - kernel detects CPUs by searching ACPI tables for local apic nodes - each CPU has its own TSS that points to its own stack. All cpus boot on the same boot stack (in sequence) but switch to its private stack as soon as they can. - final booting code in main() placed in bsp_finish_booting() which is executed only after the BSP switches to its final stack - apic functions to send startup interrupts - assembler functions to handle CPU features not needed for single cpu mode like memory barries, HT detection etc. - new files kernel/smp.[ch], kernel/arch/i386/arch_smp.c and kernel/arch/i386/include/arch_smp.h - 16-bit trampoline code for the APs. It is executed by each AP after receiving startup IPIs it brings up the CPUs to 32bit mode and let them spin in an infinite loop so they don't do any damage. - implementation of kernel spinlock - CONFIG_SMP and CONFIG_MAX_CPUS set by the build system 2010-09-15 16:09:52 +02:00			`.ifdef CONFIG_SMP`
