In certain circumstances it comes in handy to be able to boot into a second
U-Boot. But as of now it is not possible to boot a U-Boot binary that is inside
a FIT image, which is problematic for projects that e.g. need to guarantee a
unbroken chain of trust from SOC all the way into the OS, since the FIT signing
mechanism cannot be used.
This patch adds the capability to load such FIT images.
An example .its snippet (utilizing signature verification) might look
like the following:
images {
firmware@1 {
description = "2nd stage U-Boot image";
data = /incbin/("u-boot-dtb.img.gz");
type = "firmware";
arch = "arm";
os = "u-boot";
compression = "gzip";
load = <0x8FFFC0>;
entry = <0x900000>;
signature@1 {
algo = "sha256,rsa4096";
key-name-hint = "key";
};
};
};

This function returns an error code and its caller may be able to fix the
error. For example fit_handle_file() expands the device tree to fit if there
is a lack of space.
In this case the caller does not want an error displayed. It is confusing,
since it suggests that something is wrong, when it fact everything is fine.
Drop the error.

There are already two FIT options in Kconfig but the CONFIG options are
still in the header files. We need to do a proper move to fix this.
Move these options to Kconfig and tidy up board configuration:
CONFIG_FIT
CONFIG_OF_BOARD_SETUP
CONFIG_OF_SYSTEM_SETUP
CONFIG_FIT_SIGNATURE
CONFIG_FIT_BEST_MATCH
CONFIG_FIT_VERBOSE
CONFIG_OF_STDOUT_VIA_ALIAS
CONFIG_RSA
Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
be used in files that are built on the host but must also build for U-Boot
and SPL.
Note: Masahiro's moveconfig.py script is amazing.

A recent change broke the 'bootm' command on sandbox. The root cause is
using a pointer as an address. Conversion from pointer to address needs to
use map_to_sysmem() so that sandbox can do the right thing. The problem was
pre-existing but uncovered by a recent commit.
Fix this. Also move fit_get_end() to the C file to avoid needing to include
mapmem.h (and thus asm/io.h) everywhere.

The dumpimage is able to extract components contained in a FIT image:
$ ./dumpimage -T flat_dt -i CONTAINER.ITB -p INDEX FILE
The CONTAINER.ITB is a regular FIT container file. The INDEX is the poisition
of the sub-image to be retrieved, and FILE is the file (path+name) to save the
extracted sub-image.
For example, given the following kernel.its to build a kernel.itb:
/dts-v1/;
/ {
...
images {
kernel@1 {
description = "Kernel 2.6.32-34";
data = /incbin/("/boot/vmlinuz-2.6.32-34-generic");
type = "kernel";
arch = "ppc";
os = "linux";
compression = "gzip";
load = <00000000>;
entry = <00000000>;
hash@1 {
algo = "md5";
};
};
...
};
...
};
The dumpimage can extract the 'kernel@1' node through the following command:
$ ./dumpimage -T flat_dt -i kernel.itb -p 0 kernel
Extracted:
Image 0 (kernel@1)
Description: Kernel 2.6.32-34
Created: Wed Oct 22 15:50:26 2014
Type: Kernel Image
Compression: gzip compressed
Data Size: 4040128 Bytes = 3945.44 kB = 3.85 MB
Architecture: PowerPC
OS: Linux
Load Address: 0x00000000
Entry Point: 0x00000000
Hash algo: md5
Hash value: 22352ad39bdc03e2e50f9cc28c1c3652
Which results in the file 'kernel' being exactly the same as '/boot/vmlinuz-2.6.32-34-generic'.

If a specific configuraion is selected by the bootm command, e.g. with
'bootm 84000000#recoveryconf' we must honour this for not just the kernel,
but also the ramdisk and FDT.
In the conversion to using a common fit_image_load() function for loading
images from FITs (commits a51ec63 and 53f375f) this feature was lost.
Reinstate it by passing the selected configuration back from
fit_image_load() to boot_get_kernel(), then use this configuration
(which is stored in images->fit_uname_cfg) in both boot_get_ramdisk()
and boot_get_fdt().
