spl: Drop announce_boot_device()

2016-12-09T13:40:15+00:00

This task can be handled by inline code now. Drop this function.

spl: Pass the loader into spl_load_image()

2016-12-09T13:40:15+00:00

Rather than have this function figure out the correct loader again, pass
it in as a parameter.

spl: Move the loading code into its own function

2016-12-09T13:40:14+00:00

Create a boot_from_devices() function to handle trying each device. This
helps to reduce the size of the already-large board_init_r() function.

spl: Add a name to the SPL load-image methods

2016-12-09T13:40:13+00:00

It is useful to name each method so that we can print out this name when
using the method. Currently this happens using a separate function. In
preparation for unifying this, add a name to each method.

The name is only available if we have libcommon support (i.e can use
printf()).

dm: core: Handle global_data moving in SPL

2016-12-03T03:53:19+00:00

When CONFIG_SPL_STACK_R is enabled, and spl_init() is called before
board_init_r(), spl_relocate_stack_gd() will move global_data to a new
place in memory. This affects driver model since it uses a list for the
uclasses. Unless this is updated the list will become invalid. When
looking for a non-existent uclass, such as when adding a new one, the loop
in uclass_find() may continue forever, thus causing a hang.

Add a function to correct this rather obscure bug.

spl: add RAM boot device only if it is actually defined

2016-11-29T00:49:49+00:00

Some devices (e.g. dra7xx) support loading to RAM using DFU without
having direct boot from RAM support. Make sure the linker list
does not contain BOOT_DEVICE_RAM if CONFIG_SPL_RAM_DEVICE is not
enabled.

spl: Make spl_boot_list a local variable

2016-10-06T19:08:55+00:00

There is no need for this to be in the BSS region. By moving it we can delay
use of BSS in SPL. This is useful for machines where the BSS region is not
in writeable space. On 64-bit x86, SPL runs from SPI flash and it is easier
to eliminate BSS use than link SPL to run with BSS at a particular
cache-as-RAM (CAR) address.

spl: Update spl_load_simple_fit() to take an spl_image param

2016-10-06T19:08:54+00:00

Upda the SPL FIT code to use the spl_image parameter.

spl: Pass spl_image as a parameter to load_image() methods

2016-10-06T19:08:52+00:00

Rather than having a global variable, pass the spl_image as a parameter.
This avoids BSS use, and makes it clearer what the function is actually
doing.

spl: Convert spl_board_load_image() to use linker list

2016-10-06T19:08:50+00:00

Add a linker list declaration for this method and remove the explicit
switch() code. Update existing users.
