20 Got rid of the en signal, minor changes to eliminate synthesizer warnings. lynn0p 5572d 04h /sdram_controller/trunk/sdram.vhd
19 Fix for the transparent latch warning. Z80 call stack pointer test code
still works.		 lynn0p 5572d 05h /sdram_controller/trunk/sdram.vhd
18 Forgot to update the comments lynn0p 5573d 08h /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 5573d 08h /sdram_controller/trunk/sdram.vhd
16 Removed a redundant cap_en lynn0p 5575d 13h /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 5585d 14h /sdram_controller/trunk/sdram.vhd
11 consolidated capture into one process and added comments lynn0p 5586d 10h /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 5586d 14h /sdram_controller/trunk/sdram.vhd
9 Got rid of some redundant busy_n <= '0' statements lynn0p 5588d 02h /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.		 lynn0p 5588d 02h /sdram_controller/trunk/sdram.vhd
7 Reformatted the comments so they fit in 80 columns lynn0p 5596d 07h /sdram_controller/trunk/sdram.vhd
6 changes to reduce synthesizer warnings, removed unused signals, etc. lynn0p 5596d 11h /sdram_controller/trunk/sdram.vhd
2 initial checkin lynn0p 5597d 08h /sdram_controller/trunk/sdram.vhd
