AMD/Xilinx changes for v2025.01-rc5 - second
- Fix find_ram_top() return to support configs > 4GB
(cherry picked from commit 5c8ef70f08)
[Fixup: Merge commit already present in branch]
One can use ccache by keeping ccache in PATH or by providing the full
path to ccache as well. Providing the full path to ccache fails as the
current regex tries to look for ccache being the initial token during
filtering.
Do a greedy search to remove anything before ccache for regex matching.

[Fixup: Commit already present in branch]
commit e27bddff4b ("imx8m: Restrict usable memory to space below 4G boundary")
tried to adjust the usable memory limits on a 4GB boundary.
ram_top is described as 'top address of RAM used by U-Boot' and we want
to preserve that. This is defined as a phys_addr_t and unfortunately
its size differs across architectures. This has lead us to a weird
state where 32bit boards define it 'SZ_4GB - 1' and 64bit boards as
'SZ_4GB' unless it was otherwise defined.
With some recent LMB changes and specifically
commit 1a48b0be93 ("lmb: prohibit allocations above ram_top even from same bank")
the board fails to boot properly although the commit above is correct
since it's making sure that no memory above ram_top is usable -- but
added to our memory map so EFI can hand it over to the booted OS.
The reason for that is that during the LMB init we add all usable memory
in lmb_add_memory(). In that function any memory above ram_top gets added
as 'reserved' for LMB. With the current values tha's set to 0xFFFF_FFFF
for this board. Later LMB is trying to protect the memory area U-Boot lives
in with lmb_reserve_common(). The latter fails though since it tries to
add U-Boot top (which is 0xFFFF_FFFF as well) to U-Boot 'bottom'. This call
will fail since 1 byte of that memory range is already marked as 'reserved'.
Since we are close to the release, LMB seems to assume that the address
is rounded up and is the 'next address' and so does parsing and adding
memory ranges from DT files, bump the ram_top of the board by 1byte.
In the long run we should change all of the above and have 32b and 64b
platforms define ram_top identically.
Add a Fixes tag although the commit is correct, so people can figure out
the broken scenarios in the future.

eth_get_dev() returns NULL if no network device is available.
Not checking the return value leads to a crash when the device
