[OE-core] [PATCH] linux-firmware: resolve linux-firmware and microcode-ctl file conflicts

[jackie.huang at windriver.com]

From: Yue Tao <yue.tao at windriver.com>

Use alternatives mechanism to prevent linux-firmware and microcode-ctl bin
files from causing conflicts.

The error is :

error: file /lib/firmware/amd-ucode/microcode_amd.bin from install of
linux-firmware conflicts with file from package microcode-ctl-firmware

error: file /lib/firmware/amd-ucode/microcode_amd_fam15h.bin from
install of linux-firmware conflicts with file from package microcode-ctl-firmware
