There currently are two API's for requesting memory from the LMB
module, lmb_alloc() and lmb_alloc_base(). The function which does the
actual allocation is the same. Use the earlier introduced API
lmb_alloc_mem() for both types of allocation requests.

There currently are multiple allocation API's in the LMB module. There
are a couple of API's for allocating memory(lmb_alloc() and
lmb_alloc_base()), and then there are two for requesting a reservation
for a particular memory region (lmb_reserve() and
lmb_alloc_addr()). Introduce a single API lmb_alloc_mem() which will
cater to all types of allocation requests and replace lmb_reserve()
and lmb_alloc_addr() with the new API.
Moreover, the lmb_reserve() API is pretty similar to the
lmb_alloc_addr() API, with the one difference being that the
lmb_reserve() API allows for reserving any address passed to it --
the address need not be part of the LMB memory map. The
lmb_alloc_addr() does check that the address being requested is
actually part of the LMB memory map.
There is no need to support reserving memory regions which are outside
the LMB memory map. Remove the lmb_reserve() API functionality and use
the functionality provided by lmb_alloc_addr() instead. The
lmb_alloc_addr() will check if the requested address is part of the
LMB memory map and return an error if not.

This function is really just getting the data. The size comes along for
the ride. In fact this function is only reliable way to obtain the data
for an image in a FIT, since the FIT may use external data.
Rename it to fit_image_get_data()

lmb_alloc_base() is just calling lmb_alloc_base_flags() with LMB_NONE.
There's not much we gain from this abstraction, so let's remove the
former add the flags argument to lmb_alloc_base() and make the code
a bit easier to follow.

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.
[1] - https://lore.kernel.org/u-boot/20240704073544.670249-1-sughosh.ganu@linaro.org/T/#t
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).

With the introduction of separate config symbols for the SPL phase of
U-Boot, the condition checks need to be tweaked so that platforms that
enable the LMB module in SPL are also able to call the LMB API's. Use
the appropriate condition checks to achieve this.

The current LMB API's for allocating and reserving memory use a
per-caller based memory view. Memory allocated by a caller can then be
overwritten by another caller. Make these allocations and reservations
persistent using the alloced list data structure.
Two alloced lists are declared -- one for the available(free) memory,
and one for the used memory. Once full, the list can then be extended
at runtime.

android_image_get_ramdisk() will return an error if there is no ramdisk.
Using the android image without a ramdisk worked until commit
1ce8e10f3b4b ("image: Fix up ANDROID_BOOT_IMAGE ramdisk code") because
the return code wasn't checked until then. Return -ENOENT in case
there is no ramdisk and translate that into -ENOPKG in the calling
code, which will then indicate "no ramdisk" to its caller
(boot_get_ramdisk()).
This way, we can get rid of the "*rd_data = *rd_len = 0;" in the error
path, too.
With this, I'm able to boot a linux kernel using fastboot again:
fastboot --base 0x41000000 --header-version 2 --dtb /path/to/dtb \
--cmdline "root=/dev/mmcblk0p1 rootwait" boot path/to/Image

Change type of ulong env_get_bootm_low() to phys_addr_t env_get_bootm_low().
The PPC/LS systems already treat env_get_bootm_low() result as phys_addr_t,
while the function itself still returns ulong. This is potentially dangerous
on 64bit systems, where ulong might not be large enough to hold the content
of "bootm_low" environment variable. Fix it by using phys_addr_t, similar to
what env_get_bootm_size() does, which returns phys_size_t .
