So that day the meaning of BSP was clear enough.

I also got the term "LSP" from MV.

See what's EP view on "BSP".

It seems that BSP > = LSP.

Just as Wolfgang said, the meaning  varys in different
vendors. But at least "LSP" by MV doesn't include
hardware scheme and boot loader code, I think.

"LSP" is a special term defined by MV. So just to
follow the meaning as MV does.
