Hi Simon,
At present we have no standard way of passing information from SPL to U-Boot. Such information may be the size of DRAM banks or some information about the reset state of the machine,for example.
This series first adds a bloblist, which allows a list of 'blobs' to be created, each with a tag so that subsystems can store data and retrieve it later. Then it adds the SPL 'handoff' information, which uses bloblist.
I'm wondering if we could use blobs to provide information from SPL/TPL regarding "bootcount".
It seems like a better approach than the one which we do use now (as a set of magic include functions for u-boot proper and SPL/TPL).
Yes, actually I added a 'handoff' struct for general stuff like that, so it could be added there. If you like, you could try it (u-boot-dm/spl-working).
I'm going to update this series and send a new version in a few days.
