+ * We do not have hardware single-stepping on ARM, This
+ * effort is further complicated by the ARM not having a
+ * "next PC" register. Instructions that change the PC
+ * can't be safely single-stepped in a MP environment, so
+ * we have a lot of work to do:
+ *
+ * In the prepare phase:
+ * *) If it is an instruction that does anything
+ * with the CPU mode, we reject it for a kprobe.
+ * (This is out of laziness rather than need. The
+ * instructions could be simulated.)
+ *
+ * *) Otherwise, decode the instruction rewriting its
+ * registers to take fixed, ordered registers and
+ * setting a handler for it to run the instruction.
+ *
+ * In the execution phase by an instruction's handler:
+ *
+ * *) If the PC is written to by the instruction, the
+ * instruction must be fully simulated in software.
+ * If it is a conditional instruction, the handler
+ * will use insn[0] to copy its condition code to
+ * set r0 to 1 and insn[1] to "mov pc, lr" to return.
+ *
+ * *) Otherwise, a modified form of the instruction is
+ * directly executed. Its handler calls the
+ * instruction in insn[0]. In insn[1] is a
+ * "mov pc, lr" to return.
+ *
+ * Before calling, load up the reordered registers
+ * from the original instruction's registers. If one
+ * of the original input registers is the PC, compute
+ * and adjust the appropriate input register.
+ *
+ * After call completes, copy the output registers to
+ * the original instruction's original registers.
+ *
+ * We don't use a real breakpoint instruction since that
+ * would have us in the kernel go from SVC mode to SVC
+ * mode losing the link register. Instead we use an
+ * undefined instruction. To simplify processing, the
+ * undefined instruction used for kprobes must be reserved
+ * exclusively for kprobes use.

+ * To avoid the complications of mimicing single-stepping on a
+ * processor without a Next-PC or a single-step mode, and to
+ * avoid having to deal with the side-effects of boosting, we
+ * simulate or emulate (almost) all ARM instructions.
+ *
+ * "Simulation" is where the instruction's behavior is duplicated in
+ * C code. "Emulation" is where the original instruction is rewritten
+ * and executed, often by altering its registers.
+ *
+ * By having all behavior of the kprobe'd instruction completed before
+ * returning from the kprobe_handler(), all locks (scheduler and
+ * interrupt) can safely be released. There is no need for secondary
+ * breakpoints, no race with MP or preemptable kernels, nor having to
+ * clean up resources counts at a later time impacting overall system
+ * performance. By rewriting the instruction, only the minimum registers
+ * need to be loaded and saved back optimizing performance.
+ *
+ * Calling the insnslot_*_rwflags version of a function doesn't hurt
+ * anything even when the CPSR flags aren't updated by the
+ * instruction. It's just a little slower in return for saving
+ * a little space by not having a duplicate function that doesn't
+ * update the flags. (The same optimization can be said for
+ * instructions that do or don't perform register writeback)
+ * Also, instructions can either read the flags, only write the
+ * flags, or read and write the flags. To save combinations
+ * rather than for sheer performance, flag functions just assume
+ * read and write of flags.

+ * The Orion has fully programable address map. There's a separate address
+ * map for each of the device _master_ interfaces, e.g. CPU, PCI, PCIE, USB,
+ * Gigabit Ethernet, DMA/XOR engines, etc. Each interface has its own
+ * address decode windows that allow it to access any of the Orion resources.
+ *
+ * CPU address decoding --
+ * Linux assumes that it is the boot loader that already setup the access to
+ * DDR and internal registers.
+ * Setup access to PCI and PCI-E IO/MEM space is issued by core.c.
+ * Setup access to various devices located on the device bus interface (e.g.
+ * flashes, RTC, etc) should be issued by machine-setup.c according to
+ * specific board population (by using orion_setup_cpu_win()).
+ *
+ * Non-CPU Masters address decoding --
+ * Unlike the CPU, we setup the access from Orion's master interfaces to DDR
+ * banks only (the typical use case).
+ * Setup access for each master to DDR is issued by common.c.
+ *
+ * Note: although orion_setbits() and orion_clrbits() are not atomic
+ * no locking is necessary here since code in this file is only called
+ * at boot time when there is no concurrency issues.

+ * The PXA270 processor comes with a bunch of hardware on its silicon.
+ * Not all of this hardware can be used at the same time and not all
+ * is routed to module's connectors. Also it depends on the baseboard, what
+ * kind of hardware can be used in which way.
+ * -> So this file supports the main devices on the CPU card only!
+ * Refer pcm990-baseboard.c how to extend this features to get a full
+ * blown system with many common interfaces.
+ *
+ * The PCM-027 supports the following interfaces through its connectors and
+ * will be used in pcm990-baseboard.c:
+ *
+ * - LCD support
+ * - MMC support
+ * - IDE/CF card
+ * - FFUART
+ * - BTUART
+ * - IRUART
+ * - AC97
+ * - SSP
+ * - SSP3
+ *
+ * Claimed GPIOs:
+ * GPIO0 -> IRQ input from RTC
+ * GPIO2 -> SYS_ENA*)
+ * GPIO3 -> PWR_SCL
+ * GPIO4 -> PWR_SDA
+ * GPIO5 -> PowerCap0*)
+ * GPIO6 -> PowerCap1*)
+ * GPIO7 -> PowerCap2*)
+ * GPIO8 -> PowerCap3*)
+ * GPIO15 -> /CS1
+ * GPIO20 -> /CS2
+ * GPIO21 -> /CS3
+ * GPIO33 -> /CS5 network controller select
+ * GPIO52 -> IRQ from network controller
+ * GPIO78 -> /CS2
+ * GPIO80 -> /CS4
+ * GPIO90 -> LED0
+ * GPIO91 -> LED1
+ * GPIO114 -> IRQ from CAN controller
+ * GPIO117 -> SCL
+ * GPIO118 -> SDA
+ *

- *
- * To be safe, if the new OSMR0 is "very close" to the

- * Nico's comment in the previous version of this
