When dealing with filesystems that come from block devices we can get a noticeable performance gain in some use cases from having the block cache enabled. Do so by default for btrfs/ext4/FAT.

Signed-off-by: Tom Rini trini@konsulko.com --- In general this grows U-Boot itself by ~2KiB and does grow SPL by ~540 bytes when we have it present. This is only seemingly true when we have CONFIG_SPL_BLK and in turn block devices and filesystems. I'm not opposed to introducing CONFIG_SPL_BLOCK_CACHE down the line if needed, but I don't think we need it to start with. --- drivers/block/Kconfig | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)

config BLOCK_CACHE bool "Use block device cache" - default n + depends on BLK + default y if FS_BTRFS || FS_EXT4 || FS_FAT help This option enables a disk-block cache for all block devices. This is most useful when accessing filesystems under U-Boot since
