Re: [PATCH v8 0/4] riscv: Add support for Zicbo[m,z,p] instructions

[Daniel Henrique Barboza]

Hi,

Thanks everyone for the reviews. Palmer, patch 1 just landed upstream (commit
1770b2f2d3d6). You can pick patches 2-4 cleanly now.

There is another patch in the ML:

[PATCH v2 0/1] hw/riscv/virt.c: add cbo[mz]-block-size fdt properties​3 messages

that can be picked together as well.


Thanks,


Daniel
