It is used during the development & +testing of both new CPUs and the software support for them. It is essentially +the successor of the older MIPS Malta board. + +-------- + QEMU +-------- + +U-Boot can be run on a currently out-of-tree branch of QEMU with support for +the Boston board added. This QEMU code can currently be found in the "boston" +branch of git://git.linux-mips.org/pub/scm/paul/qemu.git and used like so: + + $ git clone git://git.linux-mips.org/pub/scm/paul/qemu.git -b boston + $ cd qemu + $ ./configure --target-list=mips64el-softmmu + $ make + $ ./mips64el-softmmu/qemu-system-mips64el -M boston -m 2G \ + -bios u-boot.bin -serial stdio + +Please note that QEMU will default to emulating the I6400 CPU which implements +the MIPS64r6 ISA, and at the time of writing doesn't implement any earlier CPUs +with support for the CPS features the Boston board relies upon. You will +therefore need to configure U-Boot to build for MIPSr6 in order to obtain a +binary that will work in QEMU. + +------------- + Toolchain +------------- + +If building for MIPSr6 then you will need a toolchain including GCC 5.x or +newer, or the Codescape toolchain available for download from Imagination +Technologies: + + http://codescape-mips-sdk.imgtec.com/components/toolchain/2015.06-05/ + +The "IMG GNU Linux Toolchain" is capable of building for all current MIPS ISAs, +architecture revisions & both endiannesses. + +-------- + TODO +-------- + + - AHCI support + - CPU driver + - Exception handling (+UHI?) + - Flash support + - IOCU support + - L2 cache support + - More general LCD display driver + - Multi-arch-variant multi-endian fat binary |
