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.

850d8c2b24 Fixed slight bug in config from parameterization. 2023-07-07 16:33:34 -05:00
Ross Thompson
4b3b590f21 Fpga does not correctly boot linux. I think the solution here is to revert out all substantive changes except for parameterization and then add them back in one at a time. This is necessary because the parameterization is not completed in one contiguous group of commits. 2023-06-22 12:55:49 -05:00

9bae203d1c Updated parameterization types. Modelsim version 2022.1 did requires defaults to a 32 bit integer. The base and ranges for the address decoder need to be larger. 2023-06-09 09:28:24 -05:00

340aac0934 Got the branch predictor parameterized using Lim's method. Also had to add a global enum included in both cvw.sv and the configs which defines the branch predictor types. This should be synthesizable, but I'll need to double check. 2023-05-26 16:00:14 -05:00

d3123fc00a Updated a large number of the source files to use parameters rather than `defines. Based on Lim's work. So far there is no simulation slow down. 2023-05-24 14:05:44 -05:00

63473a1477 Changed DIVN comparison from NF to NF+2. Shouldn't make a difference on our word sizes of XLEN=32/64, NF = 10/23/52) but is more proper in the general case. 2023-05-15 03:51:59 -07:00
