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:

---- --------------- -----------
CMA101 CONFIG_CMA101 32MB ram, 2 ser, 1 par, rtc, dipsw,
2x16 lcd, eth(?)

(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 CONFIG_SYS_CMA_CSn_{BASE,SIZE} and
CONFIG_SYS_{B,O}Rn_PRELIM. Also be careful of the clock settings installed
into the SCCR - via the define CONFIG_SYS_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 CONFIG_SYS_TEXT_BASE to be
the base address of the EPROM for the CPU module. This should be the
same as the value selected for CONFIG_SYS_MONITOR_BASE in
"include/config_cogent_*.h" (in fact, I have made this automatic via
the -CONFIG_SYS_TEXT_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.

/****************** DEFINES for Cogent CMA302 Flash **************************/
/*
* 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 <endian.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.
