Since we have this problem on many i.MX boards I prefer fixing this for
all affected boards, see below.

This should solve the problem for the next few years, but next time we
must find a more clever solution.

Subject: [PATCH] ARM: i.MX: increase barebox partition sizes

After doing a 'saveenv' command, it is no longer possible to boot.

The reason for this behaviour is that the 'barebox' partition has
currently
a size of 0x80000 (512 kB), which is not sufficient to store the barebox
binary. This causes the 'barebox' and 'barebox-environment' partitions
to overlap.

Fix this problem by increasing the size of the 'barebox' partition and
by placing the 'barebox-environment' right after it.

This patch increases the barebox partition for all i.MX boards to
0xe0000
