Don't worry. These terms are not clearly defined at all.

No. Both BSP and LSP are terms used by peple who try to turn software
into products that can be sold. They have vendor specific meanings.
Some vendors may bundle boot loader code with thei BSP, others don't.
Only if you buy the BSP from a hardware manufacturer there is a
chance that you will receive board schematics with it; etc. etc. And
LSP is just another marketing term to hide that somebody tries to
sell free software the same way other RTOS vendors sell BSP's. If it
includes tools or not depends again on the vendor.
My recommendation: don't care about these terms.
Best regards,

The management question ... is not _whether_ to build a pilot system
and throw it away. You _will_ do that. The only question is whether
to plan in advance to build a throwaway, or to promise to deliver the
throwaway to customers. - Fred Brooks, "The Mythical Man Month"
