[coreboot] What does *intelblocks* mean?

[Paul Menzel]

Dear coreboot folks,

In commit a554b0c5b7 (soc/intel/common/block: Add Intel XHCI driver
support) [1] the directory
`src/soc/intel/common/block/include/intelblocks` is created.

Could somebody please help me, what *intelblocks* means here, and why
*intel* is twice in the path?

Thanks,

Paul
