c45568cc4e Convert CONFIG_SYS_BOOTM_LEN to Kconfig
This converts the following to Kconfig:
   CONFIG_SYS_BOOTM_LEN

As part of this, rework error handling in boot/bootm.c so that we pass
the buffer size to handle_decomp_error as CONFIG_SYS_BOOTM_LEN will not
be available to host tools but we do know the size that we passed to
malloc().

4a8d07114e arm: apple: Don't clear framebuffer
Enable CONFIG_NO_FB_CLEAR to preserve the Asahi logo. Since that
logo is drawn on a black background also enable
CONFIG_SYS_WHITE_ON_BLACK such that text printed by U-Boot is still
visible.

6fb4f7387e arm: apple: Switch to fully dynamic mem layout
Support for Apple M1 Pro and Max will allow using a single binary for
all M1 SoCs. The M1 Pro/Max have a different memory layout. The RAM
start address is 0x100_0000_0000 instead of 0x8_0000_0000.
Replace the hardcoded memory layout with dynamic initialized
environment variables in board_late_init().

Tested on Mac Mini (2020) and Macbook Pro 14-inch (2021).

5a0973f013 arm: apple: Disable debug UART
The address of the debug UART varies differs between the M1 and
the M1 Pro/Max SoCs.  So we have to disable it to make a single
U-Boot binary that works on all SoC generations.  Leave the
settings for the base address and clock rate of the M1 in place
to make it easier to re-enable the debug UART when needed.

d42f107425 input: apple: Add support for Apple SPI keyboard
This driver adds support for the keyboard on Apple Silicon laptops.
The controller for this keyboard sits on an SPI bus and uses an
Apple-specific HID over SPI protocol. The packets sent by this
controller for key presses and key releases are fairly simple and
are decoded directly by the code in this driver and converted into
standard Linux keycodes. The same controller handles the touchpad
found on these laptops.  Packets for touchpad events are simply
ignored.

50333c94f2 nvme: apple: Add driver for Apple NVMe storage controller
Add a driver for the NVMe storage controller integrated on
Apple SoCs.  This NVMe controller isn't PCI based and deviates
from the NVMe standard in its implementation of the command
submission queue and the integration of an NVMMU that needs
to be managed.  This commit tweaks the core NVMe code to
support the linear command submission queue implemented by
this controller.  But setting up the submission queue and
managing the NVMMU controller is handled by implementing
the driver ops that were added in an earlier commit.

3dfef53610 arm: dts: apple: Add preliminary device trees
Add preliminary device trees for the Apple M1 mini (2020) and
Apple M1 Macbook Pro 13" (2020).  Device tree bindings for
the Apple M1 SoC are still being formalized and these device
trees will be synchronized with the Linux kernel as needed.

The device trees in this commit are based on the initial Apple
M1 device trees from Linux 5.13, nodes for dart, pcie, pinctrl,
pmgr, usb based on bindings on track for inclusion in Linux
5.15 and 5.16 and nodes for i2c, mailbox, nvme, pmu, spmi and
watchdog that don't have a proposed binding yet.

These device trees are provided as a reference only as U-Boot
uses the device tree passed by the m1n1 bootloader.
