In order to use the grub arm-uboot support something needs to arrange for the grub kernel to be loaded from u-boot on the various platforms, which in turn requires some platform specific knowledge (load addresses, partitions and the like). Since flash-kernel already has a bunch of infrastructure for this I thought it might be good to reuse it rather than reinventing that wheel in grub-installer (or upstream grub).
I changed grub-installer's XB-Installer-Menu-Item to 7200 (from 7400) so
it would come before flash-kernel-installer (also 7400) and added to the
grub-installer postinst (bit WIP, especially the error handling):

(full WIP patches to grub-installer and flash-kernel, which are working
on Calxeda Midway, are appended)
Just doing anna-install was not sufficient, I think because once
grub-installer's postinst finishes the top-level bootable-system
dependency is satisfied so main-menu sees no reason to configure
flash-kernel too.
Is this call to udpkg allowable? codesearch seems to suggest that the
idiom is not very widespread, only kickseed and cdrom-checker use it.
Another approach might be to split bootable-system into two parts
(perhaps only on armhf) e.g. stage1 (==flash-kernel) and stage2
(==grub).
It's worth mentioning that unless the grub-kernel can be made
relocatable it may turn out that grub-installer needs some platform
specific knowledge (the grub load address, see [0]) anyway. Leif was
going to investigate -fpie but if that doesn't pan out then I wonder if
grub-installer can/should share the flash-kernel db or if it should go
its own way? Ideally only one place would need updating for each
platform.
