84 First part of switching to proper sdspi.v, and not just the link. dgisselq 2922d 21h /xulalx25soc/
83 Fixes a bug in the LX9 build whereby the flash was never ever granted permission
to use the SPI port.		 dgisselq 2924d 01h /xulalx25soc/
82 dgisselq 2924d 20h /xulalx25soc/
81 Adds register values for the SD-Card registers. dgisselq 2924d 20h /xulalx25soc/
80 Currently working version: contains both a working DMA controller as well as
a working (as far as I can tell) SD-Card controller (writes not yet tested).		 dgisselq 2924d 20h /xulalx25soc/
79 Adds 'bench' and 'sw' targets, and automatically builds them (now). dgisselq 2924d 20h /xulalx25soc/
78 Comments out the line that caused a compiler warning--setting an unused
variable. Code should be better as a result.		 dgisselq 2924d 20h /xulalx25soc/
77 Adds register names and values for the SD card interface. dgisselq 2924d 20h /xulalx25soc/
76 Now tries to avoid reading from the stack if the stack addresses are already
known to be bad. That way, the debugger tries to preserve any bus error address
already on the buserr device.		 dgisselq 2924d 20h /xulalx25soc/
75 Added simulation capability for the SD-Card, as well as debugging output for the
DMA. (The SD-Card debug may not be fully featured, yet, but it has gotten me
to where I can talk to the card.)		 dgisselq 2924d 20h /xulalx25soc/
74 Adds the SD-card capability, and connects the debug wires to/from the uartdev
in case it needs to be debugged.		 dgisselq 2924d 20h /xulalx25soc/
73 Simplified logic. dgisselq 2924d 20h /xulalx25soc/
72 Sets XULA25 as the default. dgisselq 2924d 21h /xulalx25soc/
71 Needed to play with subtle timing to get this to build. Expect me to play
with these two clock numbers more.		 dgisselq 2924d 21h /xulalx25soc/
70 Cosmetic (minor) update. dgisselq 2924d 21h /xulalx25soc/
69 Massive logic simplification. This is also the first (verified) working
version.		 dgisselq 2924d 21h /xulalx25soc/
68 Fixes the debug ack line, so it no longer acks when there isn't a dbg_stb.
Fixed the multiply option parameter, so it sets a 3-clock multiply properly.
Adjusted the watchdog timer so that it now produces a timer that doesn't
reload--since this is pointless for a watchdog. Finally, connects a reset
line to the DMA, to make certain that resetting the CPU will also reset any
ongoing DMA operation.		 dgisselq 2924d 21h /xulalx25soc/
67 Simplifies logic, and guarantees that the minimum set value will always
produce an int. For example, if the count was X before, setting X-1 wouldn't
produce an interrupt since it had passed. Now it produces an interrupt, and
keeps the next interrupt valid.		 dgisselq 2924d 21h /xulalx25soc/
66 Simplified logic (barely). dgisselq 2924d 21h /xulalx25soc/
65 Makes the auto-reload feature a parameterized (generic) feature, so the same
code will work for both auto-reloadable and non-autoreloadable (i.e. watchdog)
timers.		 dgisselq 2924d 21h /xulalx25soc/
