+This file explains the locking and exclusion scheme used in the PCCARD
+and PCMCIA subsystems.
+
+
+A) Overview, Locking Hierarchy:
+===============================
+
+pcmcia_socket_list_rwsem - protects only the list of sockets
+- skt_mutex - serializes card insert / ejection
+ - ops_mutex - serializes socket operation
+
+
+B) Exclusion
+============
+
+The following functions and callbacks to struct pcmcia_socket must
+be called with "skt_mutex" held:
+
+ socket_detect_change()
+ send_event()
+ socket_reset()
+ socket_shutdown()
+ socket_setup()
+ socket_remove()
+ socket_insert()
+ socket_early_resume()
+ socket_late_resume()
+ socket_resume()
+ socket_suspend()
+
+ struct pcmcia_callback *callback
+
+The following functions and callbacks to struct pcmcia_socket must
+be called with "ops_mutex" held:
+
+ socket_reset()
+ socket_setup()
+
+ struct pccard_operations *ops
+ struct pccard_resource_ops *resource_ops;
+
+Note that send_event() and struct pcmcia_callback *callback must not be
+called with "ops_mutex" held.
+
+
+C) Protection
+=============
+
+1. Global Data:
+---------------
+struct list_head pcmcia_socket_list;
+
+protected by pcmcia_socket_list_rwsem;
+
+
+2. Per-Socket Data:
+-------------------
+The resource_ops and their data are protected by ops_mutex.
+
+The "main" struct pcmcia_socket is protected as follows (read-only fields
+or single-use fields not mentioned):
+
+- by pcmcia_socket_list_rwsem:
+ struct list_head socket_list;
+
+- by thread_lock:
+ unsigned int thread_events;
+
+- by skt_mutex:
+ u_int suspended_state;
+ void (*tune_bridge);
+ struct pcmcia_callback *callback;
+ int resume_status;
+
+- by ops_mutex:
+ socket_state_t socket;
+ u_int state;
+ u_short lock_count;
+ pccard_mem_map cis_mem;
+ void __iomem *cis_virt;
+ struct { } irq;
+ io_window_t io[];

+ void (*zoom_video);
+ int (*power_hook);
+ u8 resource...;
+ struct list_head devices_list;
+ u8 device_count;
+ struct pcmcia_state;
+
+
+3. Per PCMCIA-device Data:
+--------------------------
+
+The "main" struct pcmcia_devie is protected as follows (read-only fields
+or single-use fields not mentioned):
+
+
+- by pcmcia_socket->ops_mutex:
+ struct list_head socket_device_list;

+MPC5121 PSC Device Tree Bindings
+
+PSC in UART mode
+----------------
+
+For PSC in UART mode the needed PSC serial devices
+are specified by fsl,mpc5121-psc-uart nodes in the
+fsl,mpc5121-immr SoC node. Additionally the PSC FIFO
+Controller node fsl,mpc5121-psc-fifo is requered there:
+
+fsl,mpc5121-psc-uart nodes
+--------------------------
+
+Required properties :
+ - compatible : Should contain "fsl,mpc5121-psc-uart" and "fsl,mpc5121-psc"
+ - cell-index : Index of the PSC in hardware
+ - reg : Offset and length of the register set for the PSC device
+ - interrupts : <a b> where a is the interrupt number of the
+ PSC FIFO Controller and b is a field that represents an
+ encoding of the sense and level information for the interrupt.
+ - interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+
+Recommended properties :
+ - fsl,rx-fifo-size : the size of the RX fifo slice (a multiple of 4)
+ - fsl,tx-fifo-size : the size of the TX fifo slice (a multiple of 4)
+
+
+fsl,mpc5121-psc-fifo node
+-------------------------
+
+Required properties :
+ - compatible : Should be "fsl,mpc5121-psc-fifo"
+ - reg : Offset and length of the register set for the PSC
+ FIFO Controller
+ - interrupts : <a b> where a is the interrupt number of the
+ PSC FIFO Controller and b is a field that represents an
+ encoding of the sense and level information for the interrupt.
+ - interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+
+
+Example for a board using PSC0 and PSC1 devices in serial mode:
+
+serial@11000 {
+ compatible = "fsl,mpc5121-psc-uart", "fsl,mpc5121-psc";
+ cell-index = <0>;
+ reg = <0x11000 0x100>;
+ interrupts = <40 0x8>;
+ interrupt-parent = < &ipic >;
+ fsl,rx-fifo-size = <16>;
+ fsl,tx-fifo-size = <16>;
+};
+

+ interrupts = <40 0x8>;
+ interrupt-parent = < &ipic >;
+ fsl,rx-fifo-size = <16>;
+ fsl,tx-fifo-size = <16>;
+};

+pscfifo@11f00 {
+ compatible = "fsl,mpc5121-psc-fifo";
+ reg = <0x11f00 0x100>;

+GDB intends to support the following hardware debug features of BookE
+processors:
+
+4 hardware breakpoints (IAC)
+2 hardware watchpoints (read, write and read-write) (DAC)
+2 value conditions for the hardware watchpoints (DVC)
+
+For that, we need to extend ptrace so that GDB can query and set these
+resources. Since we're extending, we're trying to create an interface
+that's extendable and that covers both BookE and server processors, so
+that GDB doesn't need to special-case each of them. We added the
+following 3 new ptrace requests.
+
+1. PTRACE_PPC_GETHWDEBUGINFO
+
+Query for GDB to discover the hardware debug features. The main info to
+be returned here is the minimum alignment for the hardware watchpoints.
+BookE processors don't have restrictions here, but server processors have
+an 8-byte alignment restriction for hardware watchpoints. We'd like to avoid
+adding special cases to GDB based on what it sees in AUXV.
+
+Since we're at it, we added other useful info that the kernel can return to
+GDB: this query will return the number of hardware breakpoints, hardware
+watchpoints and whether it supports a range of addresses and a condition.
+The query will fill the following structure provided by the requesting process:
+
+struct ppc_debug_info {
+ unit32_t version;
+ unit32_t num_instruction_bps;
+ unit32_t num_data_bps;
+ unit32_t num_condition_regs;
+ unit32_t data_bp_alignment;
+ unit32_t sizeof_condition; /* size of the DVC register */
+ uint64_t features; /* bitmask of the individual flags */
+};
+
+features will have bits indicating whether there is support for:
+
+#define PPC_DEBUG_FEATURE_INSN_BP_RANGE 0x1
+#define PPC_DEBUG_FEATURE_INSN_BP_MASK 0x2
+#define PPC_DEBUG_FEATURE_DATA_BP_RANGE 0x4
+#define PPC_DEBUG_FEATURE_DATA_BP_MASK 0x8
+
+2. PTRACE_SETHWDEBUG
+
+Sets a hardware breakpoint or watchpoint, according to the provided structure:
+
+struct ppc_hw_breakpoint {
+ uint32_t version;
+#define PPC_BREAKPOINT_TRIGGER_EXECUTE 0x1
+#define PPC_BREAKPOINT_TRIGGER_READ 0x2
+#define PPC_BREAKPOINT_TRIGGER_WRITE 0x4
+ uint32_t trigger_type; /* only some combinations allowed */
+#define PPC_BREAKPOINT_MODE_EXACT 0x0
+#define PPC_BREAKPOINT_MODE_RANGE_INCLUSIVE 0x1
+#define PPC_BREAKPOINT_MODE_RANGE_EXCLUSIVE 0x2
+#define PPC_BREAKPOINT_MODE_MASK 0x3
+ uint32_t addr_mode; /* address match mode */
+
+#define PPC_BREAKPOINT_CONDITION_MODE 0x3
+#define PPC_BREAKPOINT_CONDITION_NONE 0x0
+#define PPC_BREAKPOINT_CONDITION_AND 0x1
+#define PPC_BREAKPOINT_CONDITION_EXACT 0x1 /* different name for the same thing as above */
+#define PPC_BREAKPOINT_CONDITION_OR 0x2
+#define PPC_BREAKPOINT_CONDITION_AND_OR 0x3
+#define PPC_BREAKPOINT_CONDITION_BE_ALL 0x00ff0000 /* byte enable bits */
+#define PPC_BREAKPOINT_CONDITION_BE(n) (1<<((n)+16))
+ uint32_t condition_mode; /* break/watchpoint condition flags */
+
+ uint64_t addr;
+ uint64_t addr2;
+ uint64_t condition_value;
+};
+
+A request specifies one event, not necessarily just one register to be set.
+For instance, if the request is for a watchpoint with a condition, both the
+DAC and DVC registers will be set in the same request.
+
+With this GDB can ask for all kinds of hardware breakpoints and watchpoints
+that the BookE supports. COMEFROM breakpoints available in server processors
+are not contemplated, but that is out of the scope of this work.
+
+ptrace will return an integer (handle) uniquely identifying the breakpoint or
+watchpoint just created. This integer will be used in the PTRACE_DELHWDEBUG
+request to ask for its removal. Return -ENOSPC if the requested breakpoint
+can't be allocated on the registers.
+
+Some examples of using the structure to:
+
+- set a breakpoint in the first breakpoint register
+
+ p.version = PPC_DEBUG_CURRENT_VERSION;
+ p.trigger_type = PPC_BREAKPOINT_TRIGGER_EXECUTE;
+ p.addr_mode = PPC_BREAKPOINT_MODE_EXACT;
+ p.condition_mode = PPC_BREAKPOINT_CONDITION_NONE;
+ p.addr = (uint64_t) address;
+ p.addr2 = 0;
+ p.condition_value = 0;
+
+- set a watchpoint which triggers on reads in the second watchpoint register
+
+ p.version = PPC_DEBUG_CURRENT_VERSION;
+ p.trigger_type = PPC_BREAKPOINT_TRIGGER_READ;
+ p.addr_mode = PPC_BREAKPOINT_MODE_EXACT;
+ p.condition_mode = PPC_BREAKPOINT_CONDITION_NONE;
+ p.addr = (uint64_t) address;
+ p.addr2 = 0;
+ p.condition_value = 0;
+
+- set a watchpoint which triggers only with a specific value
+
+ p.version = PPC_DEBUG_CURRENT_VERSION;
+ p.trigger_type = PPC_BREAKPOINT_TRIGGER_READ;
+ p.addr_mode = PPC_BREAKPOINT_MODE_EXACT;
+ p.condition_mode = PPC_BREAKPOINT_CONDITION_AND | PPC_BREAKPOINT_CONDITION_BE_ALL;
+ p.addr = (uint64_t) address;
+ p.addr2 = 0;
+ p.condition_value = (uint64_t) condition;
+
+- set a ranged hardware breakpoint
+
+ p.version = PPC_DEBUG_CURRENT_VERSION;
+ p.trigger_type = PPC_BREAKPOINT_TRIGGER_EXECUTE;
+ p.addr_mode = PPC_BREAKPOINT_MODE_RANGE_INCLUSIVE;
+ p.condition_mode = PPC_BREAKPOINT_CONDITION_NONE;
+ p.addr = (uint64_t) begin_range;
+ p.addr2 = (uint64_t) end_range;
+ p.condition_value = 0;
+
+3. PTRACE_DELHWDEBUG
+
+Takes an integer which identifies an existing breakpoint or watchpoint
+(i.e., the value returned from PTRACE_SETHWDEBUG), and deletes the
+corresponding breakpoint or watchpoint..
