config FS_EROFS
bool "Enable EROFS filesystem support"
help
This provides support for reading images from EROFS filesystem.
EROFS (Enhanced Read-Only File System) is a lightweight read-only
file system for scenarios which need high-performance read-only
requirements.
It also provides fixed-sized output compression support, which
improves storage density, keeps relatively higher compression
ratios, which is more useful to achieve high performance for
embedded devices with limited memory.
config FS_EROFS_ZIP
bool "EROFS Data Compression Support"
depends on FS_EROFS
select LZ4
default y
help
Enable fixed-sized output compression for EROFS.
If you don't want to enable compression feature, say N.
config FS_EROFS_ZIP_DEFLATE
bool "EROFS DEFLATE compressed data support"
depends on FS_EROFS_ZIP
select ZLIB
help
Saying Y here includes support for reading EROFS file systems
containing DEFLATE compressed data. It gives better compression
ratios than the default LZ4 format, while it costs more CPU
overhead.
DEFLATE support is an experimental feature for now and so most
file systems will be readable without selecting this option.
If unsure, say N.
