Re: [PATCH qemu] aspeed add montblanc bmc reference from fuji

[Sittisak Sinprem]

Hi Cédric,

I had fixed the function name to support in current branch,
but facing about below error while starting

./build/qemu-system-arm -machine montblanc-bmc  -drive file=~/flash-montblanc,format=raw,if=mtd -nographic -netdev tap,id=netdev0,script=no,downscript=no,ifname=tap0 -net nic,netdev=netdev0,model=ftgmac100

 

qemu-system-arm: device requires 134217728 bytes, block backend provides 27726336 bytes

Could you please use the patch below and send in your series ?

Thanks,

Subject: [PATCH] aspeed: Introduce ASPEED_RAM_SIZE helper for 32-bit hosts
  limitation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On 32-bit hosts, RAM has a 2047 MB limit. Use a macro to define the
default ram size of machines (AST2600 SoC) that can have 2 GB.
