20 Got rid of the en signal, minor changes to eliminate synthesizer warnings. lynn0p 5329d 15h /sdram_controller/trunk/sdram.vhd
19 Fix for the transparent latch warning. Z80 call stack pointer test code
still works.
lynn0p 5329d 16h /sdram_controller/trunk/sdram.vhd
18 Forgot to update the comments lynn0p 5330d 19h /sdram_controller/trunk/sdram.vhd
17 When I moved the z80 callstack pointer into SDRAM from onchip SRAM,
very hilarious things started to happen. This removes the hilarity and
restores the previous somber mood. Depending on your own design you
may or may not want to update to this revision
lynn0p 5330d 19h /sdram_controller/trunk/sdram.vhd
16 Removed a redundant cap_en lynn0p 5333d 01h /sdram_controller/trunk/sdram.vhd
12 1. rolled write recover clocks back to previous value and edited comments
2. increased 200us wait time to 300us in the init module
lynn0p 5343d 01h /sdram_controller/trunk/sdram.vhd
11 consolidated capture into one process and added comments lynn0p 5343d 21h /sdram_controller/trunk/sdram.vhd
10 Fixes to more glitches uncovered during testing with my T80 SoC. Some
ops were getting dropped on the floor when the controller needed to do
an auto refresh.
lynn0p 5344d 01h /sdram_controller/trunk/sdram.vhd
9 Got rid of some redundant busy_n <= '0' statements lynn0p 5345d 13h /sdram_controller/trunk/sdram.vhd
8 Changes made to integrate and test with my homebrew SoC design.

1. One DCM has been removed. Now requires a 100mhz clock fed in. Only
consumes one DCM, if you can find a 100mhz clock somewhere.
2. Small timing modifications to fix memory glitches between controller
and the t80 soft cpu I'm using.

7 Reformatted the comments so they fit in 80 columns lynn0p 5353d 18h /sdram_controller/trunk/sdram.vhd
6 changes to reduce synthesizer warnings, removed unused signals, etc. lynn0p 5353d 23h /sdram_controller/trunk/sdram.vhd
2 initial checkin lynn0p 5354d 19h /sdram_controller/trunk/sdram.vhd
