hw/mips: Deprecate the r4k machine
The r4k machine was introduced in 2005 (6af0bf9c7
) and its last logical change was in 2005 (9542611a6
). After that, one can count 164 maintenance commits (QEMU API changes) with the exception of 1 fix in 2015 (memory leak, commit3ad9fd5a
). This machine was introduced as a proof of concept to run a MIPS CPU. Two years later, the Malta machine was added (commit5856de80
), modeling a real platform. Note also this machine has no specification except 5 lines in the header of this file: * emulates a simple machine with ISA-like bus. * ISA IO space mapped to the 0x14000000 (PHYS) and * ISA memory at the 0x10000000 (PHYS, 16Mb in size). * All peripherial devices are attached to this "bus" with * the standard PC ISA addresses. The Linux kernel support for this machine has been dropped more than 10 years ago in commit 302922e5. It is time to deprecate this obsolete machine. Users are recommended to use the Malta board, and its hardware is well documented.
