[U-Boot-Users] [new uImage] Code available on new-image branch of u-boot-testing repo

[Bartlomiej Sieka]

Hello,

The ongoing new uImage format work that has been posted to the list in
the form of patches, is now also available from the new-image branch of
the u-boot-testing repository at Denx (thanks Wolfgang!).

You can browse the code by going to:
http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot/u-boot-testing.git;a=shortlog;h=new-image

Or you can pull it locally to take a closer look, test, etc, by using:
git pull \
git://www.denx.de/git/u-boot-testing.git/ new-image:u-boot-testing/new-image

To recap the current state of development: the above branch contains
clean-up and reorganization of the old format code, done in preparation
for adding new format handling. As the reorganization touches a lot of
common and critical code, people are encouraged to review, test and
provide feedback

Current work on new format handling will be posted to the list and made
available on the new-image branch as well.

Looking forward to the comments.

Regards,
Bartlomiej

Here is a rough patch to common/cmd_bootm.c that passed load_end down to
the do_bootm_* commands.  I haven't updated the lib_*/bootm.c at this
point.

I think this is useful to help the bootm commands know exactly what memory
is used and what is freed.  There are situations that I'd like to get
working with the new code like being able to boot a kernel at 256M and
have the ramdisk and device tree exist about this 256M base.

Hi Kumar,

In our development code for the new format we need even more data to be
passed down to do_bootm_* flavors. We are doing this by passing a
pointer to a structure:

-           do_bootm_linux (cmdtp, flag, argc, argv, hdr, verify);
+           do_bootm_linux (cmdtp, flag, argc, argv, &images, verify);


Where images is of type bootm_headers_t, defined like this:

/*
  * Legacy and FIT format headers used by do_bootm() and do_bootm_<os>()
  * routines.
  */
typedef struct bootm_headers {
        /*
         * Legacy os image header, if it is a multi component image
         * then get_ramdisk() and get_fdt() will attempt to get
         * data from second and third component accordingly.
         */
        image_header_t  *legacy_hdr_os;
        ulong           legacy_hdr_valid;

#if defined(CONFIG_FIT)
        void            *fit_hdr_os;    /* os FIT image header */
        char            *fit_uname_os;  /* os subimage node unit name */

        void            *fit_hdr_rd;    /* init ramdisk FIT img header */
        char            *fit_uname_rd;  /* init ramdisk node unit name */

#if defined(CONFIG_PPC)
        void            *fit_hdr_fdt;   /* FDT blob FIT image header */
        char            *fit_uname_fdt; /* FDT blob node unit name */
#endif
#endif
} bootm_headers_t;


Perhaps it would be a good idea to add your load_end to bootm_headers?
In any case, let's get back to this once the above mentioned code is 
posted to the ML.

Bartlomiej

Any update on the patch?

One of the ideas I have is I'd like to see if we can make it possible  
to do the equiv of bootm via a series of commands from the u-boot  
command line.

For example, I don't believe we have a way today to just decompress a  
uImage file.

Hi Kumar,

Sorry for a delayed reply, I've been quite busy recently.

As to the patch adding passing more information to do_bootm_* -- it's a
logical part of a bigger patchset that is not yet ready for posting.
Please give me a few more days to get it in shape.

Apart for using bootm machinery and the autostart env. variable (as
pointed to by Wolfgang), there isn't a direct way to do this (like a
U-Boot command for example).

What exactly would imload do?
