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.

dm: spl: Support device tree when BSS is in a different section

2015-11-04T13:49:52+00:00

At present in SPL we place the device tree immediately after BSS. This
avoids needing to copy it out of the way before BSS can be used. However on
some boards BSS is not placed with the image - e.g. it can be in RAM if
available.

Add an option to tell U-Boot that the device tree should be placed at the
end of the image binary (_image_binary_end) instead of at the end of BSS.

Note: A common reason to place BSS in RAM is to support the FAT filesystem.
We should update the code so that it does not use so much BSS.

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.

common: Display >=4GiB memory bank size

2015-08-14T09:24:20+00:00

bd->bi_dram[] has both start address and size defined as 32-bit,
which is not the case on some platforms where >=4GiB memory bank
is used. Change them to support such memory banks.

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.
