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).
The sandbox iommu driver uses the LMB module to allocate a particular
range of memory for the device virtual address(DVA). This used to work
earlier since the LMB memory map was caller specific and not
global. But with the change to make the LMB allocations global and
persistent, adding this memory range has other side effects. On the
other hand, the sandbox iommu test expects to see this particular
value of the DVA. Use the DVA address directly, instead of mapping it
in the LMB memory map, and then have it allocated.

Initialise the ram bank information for sandbox in SPL. The ram bank

The TCG event log buffer is being set at the end of ram memory. This
region of memory is to be reserved as LMB_NOMAP memory in the LMB
memory map. The current location of this buffer overlaps with the
memory region reserved for the U-Boot image, which is at the top of
the usable memory. This worked earlier as the LMB memory map was not
global but caller specific, but fails now because of the overlap.
Move the TCG event log buffer to the start of the ram memory region
instead. Move the location of the early trace buffer and the load
buffer for U-Boot(spl boot) accordingly.

The existing API for these functions is different from the rest of
U-Boot, in that any error code must be obtained from the errno variable
on failure. This variable is part of the C library, so accessing it
outside of the special 'sandbox' shim-functions is not ideal.
Adjust the API to return an error code, to avoid this. Update existing
uses to check for any negative value, rather than just -1.

Since the removal of OF_HOSTFILE logic in board_fdt_blob_setup(), the
logic for obtaining the DT is handled in the OF_BOARD option. If a
devicetree comes from a bloblist it is immediately overwritten by this
function.
Fix this by skipping the function if a devicetree is already present.
This is sort-of a fix for e7fb7896 ("sandbox: Remove OF_HOSTFILE") but
it has only come to light since bloblist was added, so I have not added
a Fixes tag.
Unfortunately it is not possible to report the correct FDT source with
the current code. It might be best to use an error-return code for
board_fdt_blob_setup() so that an error can be reported if the board
does not provide the DT.

was cleaning up linker scripts for armv7 and v8 in a similar fashion.
Several commits in the past -- e.g
commit d0b5d9da5de2 ("arm: make _end compiler-generated")
was moving symbols to be compiler generated. They were defined as c
variables in its own section to force the compiler emit relative a

same thing since [0].
So let's remove the special sections from the linker scripts, the
variable definitions from sections.c, and define them as a symbols.
It's worth noting that the linker was discarding the symbols in the
older binary completely since the symbol definition had an extra _.

Sandbox uses an API to map between addresses and pointers. This allows
it to have (emulated) memory at zero and avoid arch-specific addressing
details. It also allows memory-mapped peripherals to work.
As an example, on many machines sandbox maps address 100 to pointer
value 10000000.
However this is not correct for ACPI, if sandbox starts another program
(e.g EFI app) and passes it the tables. That app has no knowledge of
sandbox's address mapping. So to make this work we want to store
10000000 as the value in the table.
Add two new 'nomap' functions which clearly make this exeption to how
sandbox works.
This should allow EFI apps to access ACPI tables with sandbox, e.g. for
testing purposes.
