dm: common: Add memory reservation for the video uclass

2016-01-21T02:10:15+00:00

Before relocation we need to reserve memory for the video driver frame
buffers so that they can use this memory when they start up (after
relocation). Add a call to the uclass to permit this.

The current top and bottom of the region is stored in global_data so that
it can be checked post-relocation to ensure enough memory is available. No
video device should be probed before relocation.

Reserve secure memory

2015-12-15T00:57:32+00:00

Secure memory is at the end of memory, separated and reserved
from OS, tracked by gd->secure_ram. Secure memory can host
MMU tables, security monitor, etc. This is different from PRAM
used to reserve private memory. PRAM offers memory at the top
of u-boot memory, not necessarily the real end of memory for
systems with very large DDR. Using the end of memory simplifies
MMU setup and avoid memory fragmentation.

"bdinfo" command shows gd->secure_ram value if this memory is
marked as secured.

console: Add a console buffer

2015-11-20T03:27:50+00:00

It is useful to be able to record console output and provide console input
via a buffer. This provides sandbox with the ability to run a command and
check its output. If the console is set to silent then no visible output
is generated.

This also provides a means to fix the problem where tests produce unwanted
output, such as errors or warnings. This can be confusing. We can instead
set the console to silent and record this output. It can be checked later
in the test if required.

It is possible that this may prove useful for non-test situations. For
example the console output may be suppressed for normal operations, but
recorded and stored for access by the OS. That feature is not implemented
at present.

Revert "Align global_data to a 16-byte boundary"

2015-08-17T21:19:18+00:00

This causes widespread breakage due to the operation of the low-level code
in crt0.S and cro0_64.S for ARM at least.

The fix is not complicated but it seems safer to revert this for now.

This reverts commit 2afddae07523f23f77acd066ad1719f53d289f98.

Align global_data to a 16-byte boundary

2015-08-14T15:50:07+00:00

Some archs like to have larger alignment for their global data. Use 16 bytes
which suits all current archs.

Add a way to skip relocation

2015-08-05T14:43:46+00:00

When running U-Boot as an EFI application we cannot relocate since we do not
have relocation information. U-Boot has already been relocated to a suitable
address.

Add a global_data flag to control skipping relocation.

Reserve the top 16 flag bits for architecture-specific use

2015-08-05T14:42:40+00:00

Add a convention that the generic global_data only occupy the bottom 16 bits
of the flags word, so that there is less chance of a conflict. At present the
x86 flags conflict.

dm: spl: Allow device tree/driver model in board_init_f()

2015-07-21T23:39:28+00:00

Add an spl_init() function that does basic init such that board_init_f() can
use simple malloc(), device tree and driver model. Each one is set up only
if enabled for SPL.

Note: We really should refactor SPL such that there is a single
board_init_f() and rename the existing weak board_init_f() functions
provided by boards, calling them from the single board_init_f().
