Commit a first cut at ports of boot2 and loader to 64-bit MIPS, with a particular interest in (and support for) SRI International and the University of Cambridge's BERI FPGA soft-core processor. This includes micro device drivers for the Altera JTAG UART console, memory-mapped flash, and the Altera SD Card IP core in both boot2 and loader. boot2 can be written to the on-board Intel StrataFlash on the DE4 board, and loader can be placed in StrataFlash or the SD Card. Plenty of XXX comments, but works quite well locally in practice and I am using it daily. Although I had originally ported the ARM version of boot2, the current version is x86-derived as that proved more feature-complete. As we don't currently use partitions on our flash disks, support for that has been commented out relative to x86, but would be easy to add back. FDT support has not yet been hooked up, although some skeleton parts have been put in place for that. This may well be a useful starting point for ports to other 32-bit and 64-bit MIPS-ISA systems. This merge is synchronised to CheriBSD github commit e41d74fd719525d4dd7a7ee499114679165eeaf6, but with some additions of $FreeBSD.

This review aims at introducing ubldr (loader with U-Boot interface) for MIPS (32 and 64-bit, LE and BE). The changes were tested with QEMU's 'mips' target. Most of the implementation was lifted from the ARM version, the appropriate MIPS-specific things were implemented. With these changes I am able to go all the way through the u-boot->ubldr->kernel boot chain in QEMU on all combinations of bit-ness and endian-ness. For the tests I've used FAT32 disk images (as FAT32 is supported by U-boot), which include /boot/kernel/kernel and /boot/kernel/ubldr.bin In U-boot I do: fatload ide 0 <LOAD_ADDR> /boot/kernel/ubldr.bin; go <LOAD_ADDR> where LOAD_ADDR is 80800000 for 32-bit and ffffffff80800000 for 64-bit Then it's the usual ubldr that takes over and loads and starts a kernel.

Build the BERI boot loader on 64-bit MIPS (but not 32-bit MIPS). While these binaries aren't immediately useful on other MIPSes, still build them as part of mips64 world in order to expose them to tinderbox. MFC after: 3 weeks Sponsored by: DARPA, AFRL 2014-02-23 22:20:52 +00:00			`#`

Temporarily unhook BERI boot loader from the build until 32-bit MIPS properly excludes building our 64-bit only boot-loader adaptation. 2014-02-19 23:09:25 +00:00			`.endif`
