Plugin image is a firmware which can be executed by boot ROM to do
device initialization, custom settings, delay assertion, etc.
The boot ROM detects the image type using the plugin flag of the boot
data structure. If the plugin flag is 1, then the ROM uses the image
as a plugin function. The function must initialize the boot device and
copy the program image to the final location. At the end the plugin
function must return with the program image parameters.
This patch supports generating plugin images and implement a framework
for plugin code entry and exit. For any board to generate the plugin
image, the macros below must be implemented:
imx6_ddr_setting
imx6_clock_gating
imx6_qos_setting

From: Ye.Li @ 2014-11-04 8:27 UTC (permalink / raw)
To: u-boot
Update "cfg" script to build for plugin image. This default plugin
image supports the boot devices as DCD image.
To enable the plugin, must define the CONFIG_USE_PLUGIN in "mx6qarm2.h"

Update "cfg" script to build for plugin image. This default plugin
image supports the boot devices as DCD image.
To enable the plugin, must define the CONFIG_USE_PLUGIN in "mx6slevk.h"

I'd prefer:
CONFIG_IMX_BOOTROM_PLUGIN
This makes it easier to spot when looking at the config option.

Could you please elaborate a bit mode about the usage of the 'plugin image'?
When does it become useful? When should we make use of it instead of
the current DCD table?
Thanks,
