We currently provide default board names for each board in their
respective evm.c file. However for custom boards, this behaviour
overwrites the default DT as set in the defconfig
(CONFIG_DEFAULT_FDT_FILE or CONFIG_DEFAULT_DEVICE_TREE).

This patch changes the default name to be NULL which prevents this
overwrite and allows ti_set_fdt_env to instead fallback to the correct
DT as set in Kconfig.

Since commit 27cc5951c862 ("include: env: ti: add default for
do_main_cpsw0_qsgmii_phyinit"), the value of the environment variable
do_main_cpsw0_qsgmii_phyinit happened to remain '0' and couldn't be
changed without user intervention. This behavior is due to the following
cyclic dependency:
A) ti_common.env sets do_main_cpsw0_qsgmii_phyinit to '0' and its value
   can only be updated automatically by main_cpsw0_qsgmii_phyinit.
B) main_cpsw0_qsgmii_phyinit is defined in j721e.env and it can run only
   if 'do_main_cpsw0_qsgmii_phyinit' is already '1' which isn't possible
   unless the user manually assigns the value.

Fix the aforementioned cyclic dependency by using board_late_init() to
detect the QSGMII Daughtercard and set do_main_cpsw0_qsgmii_phyinit.

Additionally, to address the issue of do_main_cpsw0_qsgmii_phyinit being
'undefined' for other platforms, replace:
	if test ${do_main_cpsw0_qsgmii_phyinit} -eq 1;
with:
	if env exists do_main_cpsw0_qsgmii_phyinit;
in ti_common.env.

`dram_init()` is called by R5 SPL and U-Boot, both. It starts by
computing the size of the RAM. In verdin-am62(p), it does so by calling
`get_ram_size()`. This function computes the size of the RAM by writing
over the RAM.

When R5 computes the size of the RAM, it does not update the DT with
this size. As a result, when A53 invokes `dram_init()` again, it has to
compute the size through `get_ram_size()` again.

Commit 13c54cf588d82 and 0c3a6f748c9 add firewall over ATF's and OPTEE's
regions. This firewall is added during the R5 SPL stage of boot. So when
A53 attempts to write over RAM in `get_ram_size()`, it writes over the
protected region. Since A53 is a non-secure core, this is blocked by the
firewall.

To fix this, do the following:
    * Implement `spl_perform_board_fixups()` function for verdin-am62
      and verdin-am62p. Make this function call `fixup_memory_node()`,
      which updates the DT.
    * Add an if-block in `dram_init()`, to ensure that only R5 is able
      to call `get_ram_size()`, and that A53 reads this size from the
      DT.

First set of u-boot-at91 features for the 2026.04 cycle:

This small fixes set includes fixing 64 bit builds and some warnings for
the at91 serial driver, and some cleanup on the nand driver.

SPL-specific stuff is already in spl.c, so avoid compiling other source
files in SPL build.
