Extend Linux compat by adding kstrdup_const(), backed by lib/string.c.
This leverages U-Boots .rodata section on ARM64 to avoid pointlessly
duplicating const strings.
This is used by the Linux CCF_FULL port and may be useful elsewhere
in U-Boot.

For some platforms like Qualcomm, it isn't necessary to perform a full
DM init and scan prior to relocation, it's also particularly slow since
it runs with dcache disabled and prior to building the livetree.
The only device which needs to be probed pre-reloc is the serial
port (otherwise U-Boot will panic), however this can be found through
/chosen/stdout-path.
Therefore we can avoid scanning the entire FDT and binding devices,
instead just binding the serial port and clock driver on-demand.
This decreases the total time from power on to reaching the interactive
U-Boot shell be about 50% (from ~2.8s to 1.8s).

The downstream Raspberry Pi uses two namings for the revD
SoC device trees, both bcm2712d0-rpi-5-b and bcm2712-d-rpi-5-b

use that as it's the name that maps both upstream and downstream.

With the migration to DM_SERIAL in commit 191b10ac70 ("PowerPC /

Commit bb6f3c0f76 ("armv7: ls102xa: Update SCFG_QSPI_CLKSEL value")
broke the SPI boot on the LS1021ATSN board (ls1021atsn_qspi_defconfig)
at least.
The commit message reads
Update SCFG_QSPI_CLKSEL value : 0xC -> 0x5
which means ClusterPLL/16
The original submitted patch had the following description:
Value 0xC is reserved. Replace it with correct value 0x5 which
is ClusterPLL/16
Unfortunatly, the little information which was there, was stripped even
further. Why is 0x5 the "correct" value? In fact, it seems that the
upper bit is just ignored and thus the value 0xC translates to 0x4 which
is ClusterPLL/20. This, will result in a SPI clock of 60MHz (if the PLL
is clocked at 1.2GHz). But even that is too much for the (default) 03h
read opcode (max 50MHz). Set the value to ClusterPLL/24 which is 50MHz.

The MT7622 infracfg and pericfg drivers both use
mtk_common_clk_infrasys_init() for probe, which populates struct
mtk_clk_priv and stores gate definitions in the clk_tree. However,
both drivers were incorrectly wired to mtk_clk_gate_ops which expects
struct mtk_cg_priv with separately populated gates/num_gates/gates_offs
fields from mtk_common_clk_gate_init().
Since those fields were never set, any attempt to enable an infracfg or
pericfg gate clock (e.g. CLK_INFRA_TRNG) would fail with -EINVAL.
Switch both to mtk_clk_infrasys_ops and struct mtk_clk_priv to match
the init function.

done by adding the FDTFILES macro, which initializes two rpi_model

value is used to choose between provided FDTs. The first element of the
