This small series addresses current problem with late loading of Intel microcode in OpenWrt. Following the commit messages [1] and later discussion, late loading off the microcode can be ineffective for some processors [2] and for others disabled [3]. Also it is discouraged for any processor starting from Haswell and Silvermont. Therefore this series converts the Intel microcode bundle to an initial ram disk which is loaded with grub, so kernel has access to it as early as possible.
