The API is not very useful these days, since it doesn't support driver
model. It is laborious to add new functions to the API as there are so
many needed.
A better approach would be to create a library containing all of U-Boot,
then have the API be generated by a script containing a list of
functions, perhaps with wildcards. Then a stub could be created, with
a list of entry points, which links with and calls through into the
library.
In preparation for heading in this direction, rename some of the
existing files and directories:
- examples/api -> examples/legacy_api
- include/api*.h -> include/legacy_api*.h
- API_BUILD to LEGACY_API_BUILD

At present the membuf implementation wastes a slot in the fifo so it can
detect the difference between a full and an empty buffer.
Add the option of supporting a boolean flag, if desired. For now it is
off.
The code-size penalty is non-zero, but the space penalty is small and
could be reduced on 64-bit machines by using a u32 offset for head and

Sughosh Ganu <sughosh.ganu@linaro.org> says:
This is a follow-up from an earlier RFC series [1] for making the LMB
and EFI memory allocations work together. This is a non-rfc version
with only the LMB part of the patches, for making the LMB memory map
global and persistent.
This is part one of a set of patches which aim to have the LMB and EFI
memory allocations work together. This requires making the LMB memory
map global and persistent, instead of having local, caller specific
maps. This is being done keeping in mind the usage of LMB memory by
platforms where the same memory region can be used to load multiple
different images. What is not allowed is to overwrite memory that has
been allocated by the other module, currently the EFI memory
module. This is being achieved by introducing a new flag,
LMB_NOOVERWRITE, which represents memory which cannot be re-requested
once allocated.
The data structures (alloced lists) required for maintaining the LMB
map are initialised during board init. The LMB module is enabled by
default for the main U-Boot image, while it needs to be enabled for
SPL. This version also uses a stack implementation, as suggested by
Simon Glass to temporarily store the lmb structure instance which is
used during normal operation when running lmb tests. This does away
with the need to run the lmb tests separately.
The tests have been tweaked where needed because of these changes.
The second part of the patches, to be sent subsequently, would work on
having the EFI allocations work with the LMB API's.

Notes:
1) These patches are on next, as the alist patches have been
applied to that branch.
2) I have tested the boot on the ST DK2 board, but it would be good to
get a T-b/R-b from the ST maintainers.
3) It will be good to test these changes on a PowerPC platform
(ideally an 85xx, as I do not have one).
