Just want you to know that I and Troy are working on the following tasks for AST2700. 1. Support boot from bootmcu(riscv32) instead of u-boot(Cortex-A35) 2. Support GPIO. After we finish above tasks, we will upstream QEMU and send our patches. Thanks-Jamin > C. >

There is also this issue we discussed privately on SPI write transactions failing on the AST27000. It looked related to aspeed_smc_do_snoop() but we don't have a good fix yet. When time permits, could you please open a gitlab issue with your findings and logs, so that we don't forget. Thanks, C.

The basic model for bootmcu(risc-v) is working now, but we're looking for a way to integrate sram/mmio/dram together. The ivshmem requires PCI, it might be too complicate for our use case. There is an ivshmem-flat probably more sutiable for us. [PATCH 0/4] Add ivshmem-flat device - Gustavo Romero (kernel.org) https://lore.kernel.org/qemu-devel/20231127052024.435743-1-gustavo.romero@linaro.org/ > > > 2.
