[U-Boot] [PATCH 00/17]: ARM: SPL: Make more generic, merge DaVinci and OMAP

[Tom Rini]

Hey all,

The following patch series merges the davinci and omap-common SPL
frameworks into a single framework, CONFIG_SPL_FRAMEWORK along with a
few small cleanups to the code to make it a little smaller and more
flexible.  The end result is that davinci can now opt in on
SPL-boots-Linux by just setting the right defines and other platforms
would just need to adapt to this framework.  In my testing, davinci
gains between 300 and 700 bytes for this (not enabling the SPL OS
feature) and omap4/5/etc lose just a little bit (from the printf->puts
changes).  I've tested this on omap3_beagle (xM and classic) and
omap4_panda.  I don't have any davinci platforms that were previously
using SPL so I can't boot-test those changes but since everyone sets
CONFIG_SPL_MAX_SIZE, we're OK in that department.

To make this series easier to test I've placed it on
http://github.com/trini/u-boot WIP/spl-improvements

I've looked a little into re-reducing the size and the biggest problem I
see is that SPI a lot of informational prints that we don't need,
strictly speaking, but are nice in a normal U-Boot context.  I'm unsure
of the best way to quiet these as I don't like the idea of sprinkling
#ifndef CONFIG_SPL_BUILD in random places.
