Subject: [PATCH] Update Yosemite (440EP) to display board rev and PCI bus speed
X-Git-Tag: v1.3.0-rc1~194^2~3
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=36adff362c2c0141ff8a810d42a7e478f779130f;p=u-boot

[PATCH] Update Yosemite (440EP) to display board rev and PCI bus speed

Now the board revision and the current PCI bus speed are printed after
the board message.

Also the EBC initialising is now done via defines in the board config
file.
