Subject: target/mips: Add support of two XBurst CPUs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1980fa0a58ec8deada197e399a1c3c3b78c39e09;p=qemu.git

target/mips: Add support of two XBurst CPUs

XBurstR1 - is the MIPS32R1 CPU which aims to cover all Ingenic SoCs
older than JZ4770 and some newer.
XBurstR2 - is the MIPS32R2 CPU which aims to cover all Ingenic SoCs
starting from to JZ4770.
