[PATCH 19/49] hash: Use Kconfig to enable hashing in host tools
Simon Glass

Tue May 4 01:11:06 CEST 2021
At present when building host tools, we force CONFIG_SHA1 to be enabled
regardless of the board Kconfig setting. This is done in the image.h
header file.
Clean this up by adding new Kconfig options to enable hashing on the host,
relying on CONFIG_IS_ENABLED() to deal with the different builds.
