Currently, the bi_dram[] information is stored in the board info
structure (bd). Because bd is only valid after reserve_board(),
dram_init_banksize() must be called late in the initialization process.
This limitation is problematic, as it forces us to rely on a variety of
bespoke functions to determine board RAM, bank memory sizes, and other
early setup requirements.
By moving bi_dram[] into the global data (gd), we can run it earlier.
This is particularly convenient since boards define their own
dram_init_banksize() routines, which do not always rely on parsing
Device Tree (DT) memory nodes.
Additionally, U-Boot defaults to relocating to the top of the first memory
bank. While boards currently use custom functions to override this
behavior, having the DRAM bank information available earlier in gd makes
relocating to a different bank trivial and standardizes the process.

Introduce mach-axiado to support Axiado SoC-based boards. This adds
the platform Kconfig and build infrastructure, along with initial
SCM3005 board support using the AX3005 SoC.
Introduces AXIADO_AX3005, which selects ARM64, driver
model, GIC-v3, and Zynq UART. TARGET_SCM3005 selects ARCH_AXIADO,
allowing future SoC variants to share the platform configuration.
Secondary cores use spin-table boot. ft_board_setup() corrects
the cpu-release-addr in the FDT, which arch_fixup_fdt() overwrites
with the post-relocation address.
Add U-Boot board support for the Axiado AX3005 based targets, a quad-core
ARM Cortex-A53 (ARMv8) platform.
