Subject: [PATCH] tricorder: update flash partitioning
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The new flash layout respects posible bad blocks in sectors reserved for e.g.
SPL, u-boot, kernel, env a.s.o.

Additionally this patch prepares for U-Boot Falcon mode for boot time saving.
