| Series | bootstage: TPL and SPL improvements | expand |
At present there is a single shared address for bootstage data in both
TPL and SPL. If SPL unstashs TPL bootstage info and then stashes it again
to pass it to U-Boot, the new stash overwrites the strings of the old
stash.
Fix this by duplicating the strings into the malloc() region. This should
be a small code. Fix the header-file order at the same time.
This problem doesn't happen at the next stage (SPL->U-Boot) since U-Boot
relocates the boostage data.

Applied to u-boot-dm, thanks!
