717833b11a Removed all old references to the old flash card controller. 
Added git submodule for the flash card in addins.
Replicated flash card top level for our changes into the fpga/src directory.

Merge pull request #365 from JacobPease/boot 
Boot
Jacob's account is passing the ECA, but there are some old commits from Jan on James Stine's account which are already in the repo which were merged into this pull request which appear as anonymous users. I don't think it's possible to fix this without a significant headache.  We'd have to cherry-pick each of Jacob's 21 commits.  I'm planning to merge his work into main today/weekend and this will make the job harder. Since these commits are already part of main I'm going to merge this.

37078f3d9b Modified the LSU/IFU and caches to improve critical path. Arty A7 went from 15 to 17Mhz. I believe we can push all the way to 20+Mhz with relatively little effort. Along the way I'm fixing up the scripts build the linux images for the flash card. 2023-07-21 13:06:27 -05:00

3bf2b35704 Wow. The newest version of Vivado does not like the enums as parameters. 
The solution is simple.  I changed the type to logic [31:0] and defined macros for the branch predictor types as 32 bit integers.

142ec857ed Modified bootloader to access GUID partitions. SDC interrupt to PLIC. 
Since writing an SD card image generation script, the bootloader
needed to be altered to access individual binaries from specific
partitions. A new file, gpt.c with it's header gpt.h, have been added
to the bootloader to facilitate this.

The SDC has been added to the device tree for the VCU108
board. Additionally the SDC interrupt signal was added to the PLIC
node in the device tree. The PLIC itself  was modified to accept the
SDC interrupt signal.
