Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

Many boards use CONFIG_LMB=y but not all, e.g.
amd_versal2_mini_defconfig. Building this board with CONFIG_UNIT_TEST=y
fails:

    aarch64-linux-gnu-ld:
    test/lib/lmb.c:411:(.text.test_noreserved+0x428):
    undefined reference to `lmb_free'

We should be able to enable CONFIG_UNIT_TEST on any board.

With this patch the LMB test is only built if LMB is enabled which
overcomes the build issue.

When I modified this code I meant to accept the LGPL offer to convert the
license to GPL. However, while there is an LGPL 2.1, the next version of
the GPL after 2.0 is 3.0. Fix the license version

When abuf was introduced some test code was prevented from running using
a 'return 0' early in the functions. A comment said it crashed on
sandbox due to a 'bug' in realloc. Some time later a bug in abuf_realloc
was fixed but this test code was never enabled.

Remove the early 'return 0' instances so that the test code can run.
Also remove some checks that relied on the implementation details of the
U-Boot memory code as these can fail on sandbox which uses system memory
code. Besides that this code should be testing abuf implementation not
the underlying memory code which has its own tests.
Finally use a new #define for the allocs that are meant to fail to
ensure they do fail on all CI platforms.

This issue found by Smatch.

Heinrich Schuchardt <heinrich.schuchardt@canonical.com> says:

To implement the EFI_SYSTEM_TABLE_POINTER we need 4 MiB aligned
memory.

On the sandbox LMB uses addresses relative to the start of a page aligned
RAM buffer allocated with mmap(). This leads to a mismatch of alignment
between EFI which uses pointers and LMB which uses phys_addr_t.

Ensure that the RAM buffer used for LMB is 4 MiB aligned.

Provide a unit test for efi_alloc_aligned_pages() verifying this alignment.

Do not overwrite RAM size in dram_init().

Link: https://lore.kernel.org/r/20250608075428.32631-1-heinrich.schuchardt@canonical.com

Provide unit tests for efi_alloc_aligned_pages() and
efi_allocate_pages().

There is no need to have two separate API's for freeing up memory. Use
a single API lmb_free() to achieve this.

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.
