H A Dcpu.cde752c5e73d8fa02a3cc585ca346dae0be86c14d Thu Jan 07 09:32:04 UTC 2016 Miao Yan <yanmiaobest@gmail.com> x86: qemu: fix cpu device in smp boot

Currently, when booting with more that one CPU enabled, U-Boot scans
'cpu' node in device tree and calculates CPU number. This does not scale
well as changing CPU number also requires modifying .dts and re-compiling
U-Boot.

This patch uses fw_cfg interface provided by QEMU to detect online CPU
number at runtime, and dynamically adds 'cpu' device to U-Boot's driver
model.
