Signed-off-by: York Sun york.sun@nxp.com CC: Simon Glass sjg@chromium.org --- This is not perfect and may need some improvement. Something I didn't figure out is how to drop the name under [toolchain-wrapper]. I intended to have this format but bsettings.GetItems doesn't like it.
[toolchain-wrapper] ccache
It doesn't deal with more than one line for this setting. For now, the last setting is taken.
