[OE-core] Howto pin u-boot to a version supplied by oe-core

[Andreas Mueller]

Hi,

for gumstix overo I am in the lucky situation that vanilla u-boot v2011.03 ( and 
maybe later version too ) meets my needs.

My current approach (in angstrom environment) was quick but poor: I simply 
copied here and there without reusing anything [1].

To improve I checked u-boot_2011.03 shipped by oe-core and think that one 
exactly builds what I need - without bbappend.

So I tried in overo.conf to pin by "PREFERRED_VERSION_u-boot=":

1. "2011.03"
2. "v2011.03"
3. "v2011.03+git19b54a701811220221fc4d5089a2bb18892018ca"
4. "v2011.03+git7+19b54a701811220221fc4d5089a2bb18892018ca"

got messages like

and builds of
meta-texasinstruments/recipes-bsp/u-boot/u-boot_git.bb


How can I get the desired oe-core u-boot recipe pinned to reduce code 
redundancies?

Cheers
