In the same port, bit 0 (0x01) making the transition +\ from 0 to 1 causes the machine to reset. This is the standard I/O +\ port 92 reset. +\ +\ On a Viper, any write to port 92 will reset the machine (apparently +\ the implementation is a PAL) and the PCI bridge endian switch is +\ controlled via the PCI configuration registers. As it turns out, +\ the code for the Viper will work on a Ultra to control the bridge +\ (that's good, eaglele.fth is in arch/prep/) so there isn't any +\ problem until you go to mess with port 92 on the Ultra. +\ +\ Here's the relevant code from arch/prep/reset.fth: +\ +\ 92 pc@ dup 1 invert and 92 pc! 2 invert and 1 or 92 pc! +\ +\ If you try to reset the Ultra while running in little endian, it now +\ reads port 92 its endian bit as zero (meaning big endian) while the +\ Eagle bridge chip is really running in little endian (controlled +\ through the config registers). This bit is carefully saved and +\ stored back into the port when the reset bit is forced to zero. +\ This neatly hangs the system. From observation, bit 0 is never set +\ on entry to this code, even though it is left set. It is probably +\ reset after it's tested in the early startup code. We could try the +\ following for the reset code: +\ +\ 92 pc@ dup 1 and if +\ dup msr@ 1 and 2* or 1 invert and 92 pc! +\ then 2 invert and 1 or h# 92 pc! +\ +\ We'll have a problem with this code if we get some machine which +\ uses bit 1 (0x02) for something other than the Eagle chip endian +\ switch and it hangs the machine to set it and the machine is in +\ little endian and bit 0 of port 92 is 1 when we invoke the +\ (reset-all) word. + +\ LICENSE_BEGIN +\ Copyright (c) 1997 FirmWorks +\ +\ Permission is hereby granted, free of charge, to any person obtaining +\ a copy of this software and associated documentation files (the +\ "Software"), to deal in the Software without restriction, including +\ without limitation the rights to use, copy, modify, merge, publish, +\ distribute, sublicense, and/or sell copies of the Software, and to +\ permit persons to whom the Software is furnished to do so, subject to +\ the following conditions: +\ +\ The above copyright notice and this permission notice shall be +\ included in all copies or substantial portions of the Software. +\ +\ THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, +\ EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF +\ MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND +\ NONINFRINGEMENT.
