Due to different signature keys, the PG1 and the PG2 boards can no
longer use the same FSBL (tiboot3). This makes it impossible anyway to
maintaine a single flash.bin for both variants, so we can also split the
build.


Having two defconfigs just to make the small changes needed will be
more burden than it saves. Keeping them in sync and having your integration
layer do two different builds just adds more work than it is worth IMHO.

We (TI) are going in that direction for our HS boards and combining the
defconfigs back together now. The solution is to have the one defconfig
build both images, one for HS and one for non-HS. For you looks like you
are already calling the two PG boot images differently so this should work
(seboot_pg1.bin and seboot_pg2.bin). Just add a new full entry in
boot-image.dtsi for each (vs that #ifdef check changing the output name).

Andrew

A new target is added to indicates the build is for PG1 vs. PG2 boards.
Hence now the variants have separated defconfig files.

The runtime board_is_sr1() check does make no sense anymore, so remove
it and replace with build time check.

Documentation is updated accordingly. New binary artifacts are already
available via meta-iot2050.
