Subject: sandbox: spi: Drop command-line SPI option
X-Git-Tag: v2018.11-rc2~7^2~53
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1289e96797bfd6311f3dc656fc515a882b82701b;p=platform%2Fkernel%2Fu-boot.git

sandbox: spi: Drop command-line SPI option

At present we support specifying SPI flash devices to use in the device
tree and on the command line. Drop the second option, since it is a pain
to support nicely with driver model, and unnecessary.
