Andrew Waterman	31ad71b8a4	Remove incorrect code supporting ELF32 on RV64 and vice-versa This is technically possible by running an RV32 supervisor on an RV64 machine, but the M-mode and S-mode code would need to be compiled and linked separately.	10 years ago

Andrew Waterman	87683e74f5	Split pk functionality into pk and bbl pk is now an AEE only (i.e. it can only execute user programs). bbl is now an SEE only (i.e. it can only host kernels).	11 years ago
Andrew Waterman	1a8572a47d	Upgrade to privileged architecture 1.7	11 years ago
Andrew Waterman	33e738d643	Add ASCII art boot logo It's only printed when booting the Linux kernel. Feel free to improve the quality of the ASCII art.
