Subject: fs: Kconfig: Add a separate config for FS_CBFS
X-Git-Tag: v2025.01-rc5-pxa1908~7106
X-Git-Url: http://git.dujemihanovic.xyz/%22mailto:Murray.Jensen%40csiro.au/static/%7B%7B?a=commitdiff_plain;h=deb959991528bee05079426c189f538ad3850337;p=u-boot.git

fs: Kconfig: Add a separate config for FS_CBFS

Rather than using CMD_CBFS for both the filesystem and its command, we
should have a separate option for each. This allows us to enable CBFS
support without the command, if desired, which reduces U-Boot's size
slightly.
