[U-Boot] [PATCH v2 34/37] binman: Add support for CBFS entries
Simon Glass
sjg at chromium.org
Mon Jul 8 19:18:53 UTC 2019
Add support for putting CBFSs (Coreboot Filesystems) in an image. This
allows binman to produce firmware images used by coreboot to boot.
Signed-off-by: Simon Glass <sjg at chromium.org>

Changes in v2:
- Deal with travis's old lz4 version by skipping tests as necessary
- Skip use of cbfstool in tests if it is not available

+Entry: cbfs: Entry containing a Coreboot Filesystem (CBFS)
+----------------------------------------------------------
+
+A CBFS provides a way to group files into a group. It has a simple directory
+structure and allows the position of individual files to be set, since it is
+designed to support execute-in-place in an x86 SPI-flash device. Where XIP
+is not used, it supports compression and storing ELF files.
+
+CBFS is used by coreboot as its way of orgnanising SPI-flash contents.
+
+The contents of the CBFS are defined by subnodes of the cbfs entry, e.g.:
+
+ cbfs {
+ size = <0x100000>;
+ u-boot {
+ cbfs-type = "raw";
+ };
+ u-boot-dtb {
+ cbfs-type = "raw";
+ };
+ };
+
+This creates a CBFS 1MB in size two files in it: u-boot.bin and u-boot.dtb.
+Note that the size is required since binman does not support calculating it.
+The contents of each entry is just what binman would normally provide if it
+were not a CBFS node. A blob type can be used to import arbitrary files as
+with the second subnode below:
+
+ cbfs {
+ size = <0x100000>;
+ u-boot {
+ cbfs-name = "BOOT";
+ cbfs-type = "raw";
+ };
+
+ dtb {
+ type = "blob";
+ filename = "u-boot.dtb";
+ cbfs-type = "raw";
+ cbfs-compress = "lz4";
+ };
+ };
+
+This creates a CBFS 1MB in size with u-boot.bin (named "BOOT") and
+u-boot.dtb (named "dtb") and compressed with the lz4 algorithm.
+
+
+Properties supported in the top-level CBFS node:
+
+cbfs-arch:
+ Defaults to "x86", but you can specify the architecture if needed.
+
+
+Properties supported in the CBFS entry subnodes:
+
+cbfs-name:
+ This is the name of the file created in CBFS. It defaults to the entry
+ name (which is the node name), but you can override it with this
+ property.
+
+cbfs-type:
+ This is the CBFS file type. The following are supported:
+
+ raw:
+ This is a 'raw' file, although compression is supported. It can be
+ used to store any file in CBFS.
+
+ stage:
+ This is an ELF file that has been loaded (i.e. mapped to memory), so
+ appears in the CBFS as a flat binary. The input file must be an ELF
+ image, for example this puts "u-boot" (the ELF image) into a 'stage'
+ entry:
+
+ cbfs {
+ size = <0x100000>;
+ u-boot-elf {
+ cbfs-name = "BOOT";
+ cbfs-type = "stage";
+ };
+ };
+
+ You can use your own ELF file with something like:
+
+ cbfs {
+ size = <0x100000>;
+ something {
+ type = "blob";
+ filename = "cbfs-stage.elf";
+ cbfs-type = "stage";
+ };
+ };
+
+ As mentioned, the file is converted to a flat binary, so it is
+ equivalent to adding "u-boot.bin", for example, but with the load and
+ start addresses specified by the ELF. At present there is no option
+ to add a flat binary with a load/start address, similar to the
+ 'add-flat-binary' option in cbfstool.
+
+
+The current implementation supports only a subset of CBFS features. It does
+not support other file types (e.g. payload), adding multiple files (like the
+'files' entry with a pattern supported by binman), putting files at a
+particular offset in the CBFS and a few other things.
+
+Of course binman can create images containing multiple CBFSs, simply by
+defining these in the binman config:
+
+
+ binman {
+ size = <0x800000>;
+ cbfs {
+ offset = <0x100000>;
+ size = <0x100000>;
+ u-boot {
+ cbfs-type = "raw";
+ };
+ u-boot-dtb {
+ cbfs-type = "raw";
+ };
+ };
+
+ cbfs2 {
+ offset = <0x700000>;
+ size = <0x100000>;
+ u-boot {
+ cbfs-type = "raw";
+ };
+ u-boot-dtb {
+ cbfs-type = "raw";
+ };
+ image {
+ type = "blob";
+ filename = "image.jpg";
+ };
+ };
+ };
+
+This creates an 8MB image with two CBFSs, one at offset 1MB, one at 7MB,
+both of size 1MB.
+
+
+
