+Interrupt Mappings
+======================
+BMW uses MPC8245 discrete mode interrupts. With the following
+hardwired mappings:
+
+BCM5701 10/100/1000 Ethernet 		IRQ1
+CompactPCI Interrupt A			IRQ2
+RTC/Watchdog Interrupt			IRQ3
+Internal NS16552 UART			IRQ4
+
+
+Jumper Settings
+======================
+
+BMW has a jumper (JP600) for selecting 66, 85, or 100Mhz memory bus.
+A jumper (X) is a 0 bit.
+
+Hence 66= 10110
+      85= 11000

+Cogent Modular Architecture configuration
+-----------------------------------------
+
+As the name suggests, the Cogent platform is a modular system where
+you have a motherboard into which plugs a cpu module and one or more
+i/o modules. This provides very nice flexibility, but makes the
+configuration task somewhat harder.
+
+The possible Cogent motherboards are:
+
+Code		Config Variable		Description
+----		---------------		-----------
+
+CMA101		CONFIG_CMA101		32MB ram, 2 ser, 1 par, rtc, dipsw,

+					rtc, ps/2 kbd/mse, 2x16 lcd, 2xPCI,
+					10/100TP eth

+CMA150		CONFIG_CMA150		8MB ram, 1MB flash, 2 ser, 1 par, rtc,
+					ps/2 kbd/mse, 2x16 lcd
+
+The possible Cogent PowerPC CPU modules are:
+
+Code		Config Variable		Description

+					BDM
+
+(there are a lot of other cpu modules with ARM, MIPS and M-CORE CPUs,
+but we'll worry about those later).
+
+The possible Cogent CMA I/O Modules are:
+
+Code		Config Variable		Description
+----		---------------		-----------
+
+CMA302		CONFIG_CMA302		up to 16M flash, ps/2 keyboard/mouse
+CMA352		CONFIG_CMA352		CMAbus <=> PCI
+
+Currently supported:
+
+	Motherboards:	CMA102
+	CPU Modules:	CMA286-60-OLD
+	I/O Modules:	CMA302 I/O module
+
+To configure, perform the usual U-Boot configuration task of editing
+"include/config_cogent_mpc8xx.h" and reviewing all the options and
+settings in there. In particular, check the chip select values
+installed into the memory controller's various option and base
+registers - these are set by the defines CFG_CMA_CSn_{BASE,SIZE} and
+CFG_{B,O}Rn_PRELIM. Also be careful of the clock settings installed
+into the SCCR - via the define CFG_SCCR. Finally, decide whether you
+want the serial console on motherboard serial port A or on one of the
+8xx SMC ports, and set CONFIG_8xx_CONS_{SMC1,SMC2,NONE} accordingly
+(NONE means use Cogent motherboard serial port A).
+
+Then edit the file "cogent/config.mk". Firstly, set TEXT_BASE to be
+the base address of the EPROM for the CPU module. This should be the
+same as the value selected for CFG_MONITOR_BASE in
+"include/config_cogent_*.h" (in fact, I have made this automatic via
+the -DTEXT_BASE=... option in CPPFLAGS).
+
+Finally, set the values of the make variables $(CMA_MB) and $(CMA_IOMS).
+
+$(CMA_MB) is the name of the directory that contains support for your
+motherboard. At this stage, only "cma10x" exists, which supports the
+CMA101 and CMA102 motherboards - but only selected devices, namely
+serial, lcd and dipsw.
+
+$(CMA_IOMS) is a list of zero or more directories that contain
+support for the i/o modules you have installed. At this stage, only
+"cma302" exists, which supports the CMA302 flash i/o module - but
+only the flash part, not the ps/2 keyboard and mouse interfaces.
+
+There should be a make variable for each of the above directories,
+which is the directory name with "_O" appended. This make variable is
+a list of object files to compile from that directory and include in
+the library.
+
+	e.g. cma10x_O = serial.o ...
+
+That's it. Good Luck.

+CPU module revisions
+--------------------
+
+My cpu module has the model number "CMA286-60-990526-01". My motherboard
+has the model number "CMA102-32M-990526-01". These are both fairly old,
+and may not reflect current design. In particular, I can see from the
+Cogent web site that the CMA286 has been significantly redesigned - it
+now has on board RAM (4M), ethernet 10baseT PHY (on SCC2), 2 serial ports
+(SMC1 and SMC2), and 48pin DIN for the FEC (if present i.e. MPC860T), and
+also the EPROM is 512K.
+
+My CMA286-60 has none of this, and only 128K EPROM. In addition, the CPU
+clock is listed as 66MHz, whereas mine is 33.333MHz.
+
+Clocks
+------
+
+Quote from my "CMA286 MPC860/821 User's Manual":
+
+"When setting up the Periodic Interrupt Timer (PIT), be aware that the
+CMA286 places the MPC860/821 in PLL X1 Mode. This means that we feed
+a 25MHz clock directly into the MPC860/821. This mode sets the divisor
+for the PIT to be 512. In addition, the Time Base Register (TMB)
+divisor is set to 16."
+
+I interpreted this information to mean that EXTCLK is 25MHz and that at
+power on reset, MODCK1=1 and MODCK2=0, which selects EXTCLK as the
+source for OSCCLK and PITRTCLK, sets RTDIV to 512 and sets MF (the
+multiplication factor) to 1 (I assume this is what they mean by X1
+mode above). MF=1 means the cpus internal clock runs at the same
+rate as EXTCLK i.e. 25MHz.
+
+Furthermore, since SCCR[TBS] (the Time Base Source selector bit in the
+System Clock and Reset Control register) is set in the cpu initialisation
+code, the TMBCLK source is forced to be GCLK2 and the TMBCLK prescale is
+forced to be 16. This results in TMBCLK=1562500.
+
+One problem - since PITRTCLK source is EXTCLK (25Mhz) and RTDIV is 512,
+PITRTCLK will be 48828.125 (huh?). Another quote from the MPC860 Users
+Manual:
+
+"When used by the real-time clock (RTC), the PITRTCLK source is first
+divided as determined by RTDIV, and then divided in the RTC circuits by
+either 8192 or 9600. Therefore, in order for the RTC to count in
+seconds, the clock source must satisfy:
+
+	(EXTCLK or OSCM) / [(4 or 512) x (8192 or 9600)] = 1
+
+The RTC will operate with other frequencies, but it will not count in
+units of seconds."
+
+Therefore, the internal RTC of the MPC860 is not going to count in
+seconds, so we must use the motherboard RTC (if we need a RTC).
+
+I presume this means that they do not provide a fixed oscillator for
+OSCM. The code in get_gclk_freq() assumes PITRTCLK source is OSCM,
+RTDIV is 4, and that OSCM/4 is 8192 (i.e. a ~32KHz oscillator). Since
+the CMA286-60 doesn't have this (at least mine doesn't) we can't use
+the code in get_gclk_freq().
+
+Finally, it appears that the internal clock in my CMA286-60 is actually
+33.333MHz. Which makes TMBCLK=2083312.5 (another huh?) and
+PITRTCLK=65103.515625 (bloody hell!).
+
+If anyone finds anything wrong with the stuff above, I would appreciate
+an email about it.

+
+/*
+ * Quoted from the CMA302 manual:
+ *
+ * Although the CMA302 supports 64-bit reads, all writes must be done with
+ * word size only. When programming the CMA302, the FLASH devices appear as 2
+ * banks of interleaved, 32-bit wide FLASH. Each 32-bit word consists of four
+ * 28F008S5 devices. The first bank is accessed when the word address is even,
+ * while the second bank is accessed when the word address is odd. This must
+ * be taken into account when programming the desired word. Also, when locking
+ * blocks, software must lock both banks. The CMA302 does not directly support
+ * byte writing.  Programming and/or erasing individual bytes is done with
+ * selective use of the Write Command.  By not placing the Write Command value
+ * on a particular byte lane, that byte will not be written with the following
+ * Write Data. Also, remember that within a byte lane (i.e. D0-7), there are
+ * two 28F008S5 devices, one for each bank or every other word.
+ *
+ * End quote.
+ *
+ * Each 28F008S5 is 8Mbit, with 8 bit wide data. i.e. each is 1Mbyte. The
+ * chips are arranged on the CMA302 in multiples of two banks, each bank having
+ * 4 chips. Each bank must be accessed as a single 32 bit wide device (i.e.
+ * aligned on a 32 bit boundary), with each byte lane within the 32 bits (0-3)
+ * going to each of the 4 chips and the word address selecting the bank, even
+ * being the low bank and odd the high bank. For 64bit reads, both banks are
+ * read simultaneously with the second bank on byte lanes 4-7. Each 28F008S5
+ * consists of 16 64Kbyte "block"s. Before programming a byte, the block that
+ * the byte resides within must be erased. So if you want to program contiguous
+ * memory locations, you must erase all 8 chips at the same time. i.e. the
+ * flash on the CMA302 can be viewed as a number of 512Kbyte blocks.
+ *
+ * Note: I am going to treat banks as 8 Mbytes (1Meg of 64bit words), whereas
+ * the example code treats them as a pair of interleaved 1 Mbyte x 32bit banks.

+
+/*
+ * Cogent Motherboard Address Map
+ *
+ * The size of a Cogent motherboard address space is 256 Mbytes (i.e. 28 bits).
+ *
+ * The first 32 Mbyte (0x0000000-0x1FFFFFF) is usually RAM. The following
+ * 3 x 32 Mbyte areas (0x2000000-0x3FFFFFF, 0x4000000-0x5FFFFFF and
+ * 0x6000000-0x7FFFFFF) are general I/O "slots" (slots 1, 2 and 3).
+ * Most other motherboard devices have registers mapped into the area
+ * 0xE000000-0xFFFFFFF (Motherboard I/O slot?). The area 0x8000000-0xDFFFFFF
+ * is free for whatever.
+ *
+ * The location of the motherboard address space in the physical address space
+ * of the cpu is given by CMA_MB_BASE. This value is determined by the cpu
+ * module plugged into the motherboard and is configured above.
+ *
+ * Motherboard I/O devices mapped into the area (0xE000000-0xFFFFFFF)
+ * generally only use byte lane 0 (D0-7) for their transfers, i.e. only
+ * 8 bit, or 1 byte, transfers can take place, so all the registers are
+ * only 8 bits wide. The exceptions are the motherboard flash, which uses
+ * byte lanes 0 and 1 (i.e. 16 bits), and the mapped PCI address space.
+ *
+ * I/O registers within the mapped motherboard devices are 64 bit aligned
+ * i.e. they are 8 bytes apart. For big endian addressing, the 8 bit register
+ * will be at byte 7 (the address + 7). For little endian addressing, the
+ * register will be at byte 0 (the address + 0). To learn the endianess
+ * we must include <asm/byteorder.h>
+ *
+ * Take the CMA102 and CMA111 motherboards as examples...
+ *
+ * The CMA102 has three CMABus I/O Expansion slots and no PCI bridge. The 3
+ * CMABus slots are each mapped directly onto the three general I/O slots.
+ *
+ * The CMA111 has only one CMABus I/O Expansion slot, but has a V360EPC PCI
+ * bridge. The CMABus slot is mapped onto general I/O slot 1. The standard
+ * PCI Bus space is mapped onto general I/O slot 2, with a small area at the
+ * top reserved for access to the V360EPC registers (0x5FF0000-0x5FFFFFF).
+ * I/O slot 3 is unused. The extended PCI Bus space is mapped onto the area
+ * 0xA000000-0xDFFFFFF.

+ppcboot for a CU824 board
+---------------------------
+
+CU824 has two banks of flash 8MB each. In board's notation, bank 0 is
+the one at the address of 0xFF800000 and bank 1 is the one at the
+address of 0xFF000000. On power-up the processor jumps to the address
+of 0xFFF00100, the last megabyte of the bank 0 of flash. Thus,
+U-Boot is configured to reside in flash starting at the address of
+0xFFF00000. The environment space is not embedded in the U-Boot code
+and is located in flash separately from U-Boot, at the address of
+0xFF008000.
