[RFC PATCH 0/2] Add a linker-list consistency checker

[Simon Glass]

Linker lists rely on contiguous symbols laid out at consistent
alignment. When the linker inserts padding the start/end pointer
arithmetic silently produces garbage, leading to baffling runtime
failures such as wildly negative test counts.

Add a small Python script that walks the linked u-boot image with
nm -S, flags gaps that look like padding, and verifies that each
list span is a whole multiple of its element size. Wire it into
the Makefile so it runs after the final link.
