common/image.c: Fix regression with ramdisk load/entry points in FIT

2013-07-12T19:04:43+00:00

A FIT image with a ramdisk that sets the entry or load points to 0x0
must be treated as meaning "leave in place" and NOT "relocate to 0x0".
This regression was introduced in a51ec63.

bootm: Use selected configuration for ramdisk and fdt

2013-07-12T14:32:39+00:00

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().

Clarify bootm OS arguments

2013-06-26T14:16:41+00:00

At present the arguments to bootm are processed in a somewhat confusing
way. Sub-functions must know how many arguments their calling functions
have processed, and the OS boot function must also have this information.
Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in
the same way.

Adjust the code so that arguments are removed from the list before calling
a sub-function. This means that all functions can know that argv[0] is the
first argument of which they need to take notice.

image: Use fit_image_load() to load ramdisk

2013-06-04T20:06:31+00:00

Use the new common code to load a ramdisk. The functionality should not
change.

image: Add device tree setup to image library

2013-05-14T19:37:25+00:00

This seems to be a common function for several architectures, so create
a common function rather than duplicating the code in each arch.

Also make an attempt to avoid introducing #ifdefs in the new code, partly
by removing useless #ifdefs around function declarations in the image.h
header.

image: Split libfdt code into image-fdt.c

2013-05-14T19:37:25+00:00

The image file is still very large, and some of the code is only used when
libfdt is in use. Move this code into a new file.

image: Remove remaining #ifdefs in image-fit.c

2013-05-14T19:37:25+00:00

There are only two left. One is unnecessary and the other can be moved
to the header file.

sandbox: image: Add support for booting images in sandbox

2013-05-14T19:37:25+00:00

Much of the image code uses addresses as ulongs and pointers interchangeably,
casting between the two forms as needed.

This doesn't work with sandbox, which has a U-Boot RAM buffer which is
separate from the host machine's memory.

Adjust the cost so that translating from a U-Boot address to a pointer uses
map_sysmem(). This allows bootm to work correctly on sandbox.

Note that there are no exhaustive tests for this code on sandbox, so it is
possible that some dark corners remain.

image: Rename fit_image_check_hashes() to fit_image_verify()

2013-05-14T19:37:25+00:00

This is the main entry point to the FIT image verification code. We will
be using it to handle image verification with signatures, so rename the
function.

The FIT code is about half the size of the >3000-line image.c. Split this
code into its own file.
