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.

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. + +Murray Jensen <Murray.Jensen@csiro.au> +21-Aug-00 diff --git a/roms/u-boot/board/cogent/dipsw.c b/roms/u-boot/board/cogent/dipsw.c new file mode 100644 index 00000000..ecfbc259 --- /dev/null +++ b/roms/u-boot/board/cogent/dipsw.c @@ -0,0 +1,50 @@ +#include <common.h> +#include "dipsw.h" + +unsigned char +dipsw_raw(void) +{ + return cma_mb_reg_read(&((cma_mb_dipsw *)CMA_MB_DIPSW_BASE)->dip_val); +} + +unsigned char +dipsw_cooked(void) +{ + unsigned char val1, val2, mask1, mask2; + + val1 = dipsw_raw(); + + /* + * we want to mirror the bits because the low bit is switch 1 and high + * bit is switch 8 and also invert them because 1=off and 0=on, according + * to manual. + * + * this makes the value more intuitive i.e. + * - left most, or high, or top, bit is left most switch (1); + * - right most, or low, or bottom, bit is right most switch (8) + * - a set bit means "on" and a clear bit means "off" + */ + + val2 = 0; + for (mask1 = 1 << 7, mask2 = 1; mask1 > 0; mask1 >>= 1, mask2 <<= 1) + if ((val1 & mask1) == 0) + val2 |= mask2; + + return (val2); +} + +void +dipsw_init(void) +{ + unsigned char val, mask; + + val = dipsw_cooked(); + + printf("|"); + for (mask = 1 << 7; mask > 0; mask >>= 1) + if (val & mask) + printf("on |"); + else + printf("off|"); + printf("\n"); +} diff --git a/roms/u-boot/board/cogent/dipsw.h b/roms/u-boot/board/cogent/dipsw.h new file mode 100644 index 00000000..4f52fd43 --- /dev/null +++ b/roms/u-boot/board/cogent/dipsw.h @@ -0,0 +1,3 @@ +extern unsigned char dipsw_raw(void); +extern unsigned char dipsw_cooked(void); +extern void dipsw_init(void); diff --git a/roms/u-boot/board/cogent/flash.c b/roms/u-boot/board/cogent/flash.c new file mode 100644 index 00000000..1da8f10a --- /dev/null +++ b/roms/u-boot/board/cogent/flash.c @@ -0,0 +1,633 @@ +/* + * (C) Copyright 2000 + * Wolfgang Denk, DENX Software Engineering, wd@denx.de. + * + * SPDX-License-Identifier: GPL-2.0+ + */ + +#include <common.h> +#include "flash.h" +#include <linux/compiler.h> + +flash_info_t flash_info[CONFIG_SYS_MAX_FLASH_BANKS]; /* info for FLASH chips */ + +#if defined(CONFIG_ENV_IS_IN_FLASH) +# ifndef CONFIG_ENV_ADDR +# define CONFIG_ENV_ADDR (CONFIG_SYS_FLASH_BASE + CONFIG_ENV_OFFSET) +# endif +# ifndef CONFIG_ENV_SIZE +# define CONFIG_ENV_SIZE CONFIG_ENV_SECT_SIZE +# endif +# ifndef CONFIG_ENV_SECT_SIZE +# define CONFIG_ENV_SECT_SIZE CONFIG_ENV_SIZE +# endif +#endif + +/*----------------------------------------------------------------------- + * Functions + */ +static int write_word (flash_info_t *info, ulong dest, ulong data); + +/*----------------------------------------------------------------------- + */ + + +#if defined(CONFIG_CMA302) + +/* + * probe for the existence of flash at address "addr" + * 0 = yes, 1 = bad Manufacturer's Id, 2 = bad Device Id + */ +static int +c302f_probe_word(c302f_addr_t addr) +{ + /* reset the flash */ + *addr = C302F_BNK_CMD_RST; + + /* check the manufacturer id */ + *addr = C302F_BNK_CMD_RD_ID; + if (*C302F_BNK_ADDR_MAN(addr) != C302F_BNK_RD_ID_MAN) + return 1; + + /* check the device id */ + *addr = C302F_BNK_CMD_RD_ID; + if (*C302F_BNK_ADDR_DEV(addr) != C302F_BNK_RD_ID_DEV) + return 2; + +#ifdef FLASH_DEBUG + { + int i; + + printf("\nMaster Lock Config = 0x%08lx\n", + *C302F_BNK_ADDR_CFGM(addr)); + for (i = 0; i < C302F_BNK_NBLOCKS; i++) + printf("Block %2d Lock Config = 0x%08lx\n", + i, *C302F_BNK_ADDR_CFG(i, addr)); + } +#endif + + /* reset the flash again */ + *addr = C302F_BNK_CMD_RST; + + return 0; +} + +/* + * probe for Cogent CMA302 flash module at address "base" and store + * info for any found into flash_info entry "fip".

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.

+ * + * 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. + */ + +#define CMA_MB_RAM_BASE (CONFIG_SYS_CMA_MB_BASE+0x0000000) +#define CMA_MB_RAM_SIZE 0x2000000 /* dip sws set actual
