sunxi: remove usage of legacy LED API
We are trying to get rid of the legacy LED API and PinePhone is one of
the last ones requiring it.
Unlike all other users of the legacy LED API, PinePhone is controlling
the GPIO LED in SPL. Unfortunately, Sunxi doesn't enable DM support in
SPL because of tight space constraints, so we cannot make use of the
modern LED framework as that is based on DM_GPIO.
Since PinePhone is the last user of this API, I'm moving the logic to
Sunxi SPL code and will let this community decide how to handle this hot
potato.
The logic is extremely simplified as only one GPIO LED is currently
controlled in SPL by PinePhone. No need for handling multiple LEDs or
inverted polarity, let's keep it simple.
This however allows us to use the modern LED framework once in U-Boot
proper since this logic won't collide with the new framework.
Since the only misc drivers that were compiled in SPL were guarded by
CONFIG_LED_STATUS and CONFIG_LED_STATUS_GPIO, we can also disable
CONFIG_SPL_DRIVERS_MISC (which does nothing anymore).
This also saves some space for PinePhone in SPL and proper.

kbuild: strip sub_make_done from test-script environment
The exported sub_make_done variable leaks into the environment of all
child processes. When make targets like tcheck spawn independent
make-invocations with O=, those child-makes inherit sub_make_done=1,
skip the KBUILD_OUTPUT setup and try to build in the source tree.
A global 'unexport sub_make_done' cannot be used because the build
system itself re-invokes the top-level Makefile for syncconfig (via
'$(MAKE) -f $(srctree)/Makefile syncconfig'). Without sub_make_done,
that child make re-enters the KBUILD_OUTPUT block and recomputes
abs_objtree. With a relative O= path this resolves to a nested
directory (e.g. build/build/) where .config does not exist.
Instead, use 'env -u sub_make_done' in the test-target recipes so only
the test scripts see a clean environment. This allows their child make
invocations to process O= correctly without affecting internal kbuild
recursion.
This is not strictly a bugfix, but compare with:

There is already generic and simple linker script (arch/u-boot-elf.lds)
which can be also used without any modification.

spl: spi: fix loss of spl_load() error on soft reset
When CONFIG_SPI_FLASH_SOFT_RESET is enabled, spi_nor_remove() is called
after spl_load() to switch the flash back to legacy SPI mode. However,
the return value of spi_nor_remove() unconditionally overwrites the
return value of spl_load(), discarding any load error.
Fix this by preserving the spl_load() error and only propagating the
spi_nor_remove() error as a fallback. Also log a message when
spi_nor_remove() fails, since in the case where spl_load() already
failed its error would otherwise be silently discarded.

lmb: Reinstate access to memory above ram_top
Revert commit eb052cbb896f ("lmb: add and reserve memory above ram_top")
and commit 1a48b0be93d4 ("lmb: prohibit allocations above ram_top even from
same bank"). These are based on incorrect premise of the first commit, that
"U-Boot does not use memory above ram_top". While U-Boot itself indeed does
not and should not use memory above ram_top, user can perfectly well use
that memory from the U-Boot shell, for example to load content in there.
Currently, attempt to use that memory to load large image using TFTP ends
with "TFTP error: trying to overwrite reserved memory...". With this change
in place, the memory can be used again.

net: Move network PHY under NETDEVICES
A number of network PHY drivers have Kconfig dependencies on various
network drivers under NETDEVICES. This is in addition to logical
dependencies of network PHYs needing network drivers. Resolve the
Kconfig problems by moving the network PHY lines to be after the network
devices, within the overall NETDEVICES guard.

net: lwip: scale buffer pool size with TFTP block size
TFTP transfers fail when tftpblocksize is set to 8192 or larger due to
insufficient buffer resources for IP fragment reassembly.
Calculate PBUF_POOL_SIZE and IP_REASS_MAX_PBUFS dynamically based on
CONFIG_TFTP_BLOCKSIZE using IP fragmentation boundaries (1480 usable
bytes per fragment at 1500 MTU). The pool size includes headroom for
TX, ARP, and protocol overhead, while ensuring PBUF_POOL_SIZE remains
greater than IP_REASS_MAX_PBUFS as required by lwIP.

net: lwip: Fix PBUF_POOL_BUFSIZE when PROT_TCP_LWIP is disabled
The PBUF_POOL_BUFSIZE ends up being only 592 bytes, instead of 1514,
when PROT_TCP_LWIP Kconfig option is disabled. This results in a full
Ethernet frame requiring three PBUFs instead of just one.
This happens because the PBUF_POOL_BUFSIZE constant depends on the value
of a TCP_MSS constant, something that defaults to 536 when PROT_TCP_LWIP
is disabled.
