This patch updates U-Boot and the boot script to the latest production
version as described in this post:
http://boundarydevices.com/u-boot-2013-07-release/
For Yocto users, it also adds support for processor and memory
configutations other than the standard Quad-core/1GB option.

To build U-Boot for other CPU or memory combinations, you can set
the UBOOT_MACHINE variable in your local.conf according to the
following table:
Processor Memory Configuration
-------------- ------ --------------------
i.MX6Quad/Dual 1GB nitrogen6q_config
i.MX6Quad/Dual 2GB nitrogen6q2g_config
i.MX6Dual-Lite 1GB nitrogen6dl_config
i.MX6Dual-Lite 2GB nitrogen6dl2g_config
i.MX6Solo 512MB nitrogen6s_config
i.MX6Solo 1GB nitrogen6s1g_config
This patch also updates the boot script to allow support
for device-tree-enabled kernels in preparation for a 3.5.7
alpha release.
OK, Do you mean today it does not have support for device-tree?
The boot script didn't/doesn't. U-Boot itself did/does.
If a device-tree binary (imx6q_sabrelite.dtb or imx6q_nitrogen6x.dtb)
is found in the root directory of the boot (p1) partition, it
will be passed to the kernel.

Great, I like it.
Thanks. We still need to do an update to support our
Nitrogen6_Lite board (solo only, Broadcom WiFi).
That one needs a separate machine though because the
feature-set is different.
