In newer 1.2 PinePhone board revisions LIS3MDL magnetometer was replaced by
AF8133J. They use the same PB1 pin in different modes.
LIS3MDL uses it as an gpio input to handle interrupt.
AF8133J uses it as an gpio output as a reset signal.
It wasn't possible at runtime to enable both device tree
nodes and detect supported sensor at probe time.
AF8133J has reset pin (PB1) connected to the SoC. By default AF8133J
is in a reset state and don't respond to probe request on I2C
bus. Extra code would be needed to handle reset signal. Therefore this
code uses LIS3MDL magnetometer instead of AF8133J.
Introducing new dts 1.2b with AF8133J sensor would require probing in
SPL. That would lead to pulling in into SPL I2C controller driver,
RSB controller driver, introducing new AXP803 driver to power-up
sensors for probe. It's working, but SPL is pretty size-constrained on
A64 and doesn't have much space. Therefore fdt fixup is done in U-Boot
proper without introducing new board revision and new dts.

pstore will allow users to catch kernel crashes and report them to
developers. Modern (Android) phones have pstore usually enabled to get
information about kernel crash, since it's the simplest way to get
kernel backtrace on mobile device without serial console. Usually it's
enabled by default in distribution kernels like Debian.
CONFIG_PSTORE=y
CONFIG_PSTORE_RAM=m
systemd has service that automatically handles pstore and saves them
in /var/lib/pstore for later usage.
In general any DRAM address, that isn't overwritten during a boot is
suitable for pstore.
Range from 0x40000000 - 0x50000000 is heavily used by u-boot for
internal use and to load kernel, fdt, fdto, scripts, pxefile and ramdisk
later in the boot process. Ramdisk start address is 0x4FF00000,
initramfs for kernel with some hacking features and debug info enabled
can take more than 100Mb and final address will be around 0x58000000.
Address 0x61000000 will most likely not overlap with that.

Commit 08574ed339fb ("Convert CONFIG_SYS_MONITOR_LEN to Kconfig") moved
the definition of said config variable from the common sunxi header to
*every board's* defconfig.
This is a platform choice, not board specific, so remove the variable
from there, instead set the one value for all Allwinner boards in
Kconfig.

This converts the following to Kconfig:
CONFIG_SYS_MONITOR_LEN
To do this, we set a default of 0 for everyone because there are a
number of cases where we define CONFIG_SYS_MONITOR_LEN but the only
impact is that we set TOTAL_MALLOC_LEN to be CONFIG_SYS_MALLOC_LEN +
CONFIG_ENV_SIZE, so we must continue to allow all boards to set this
value. Update the SPL code to use 200 KB as the default raw U-Boot size
directly, if we don't have a real CONFIG_SYS_MONITOR_LEN value.

When some configuration symbols were converted from header files to
Kconfig, their values were placed into *every* defconfig file.
Since we now have sensible per-SoC defaults defined in Kconfig, those
values are now redundant, and can just be removed.
This affects CONFIG_SPL_STACK, CONFIG_SYS_PBSIZE, CONFIG_SPL_MAX_SIZE,
and CONFIG_SYS_BOOTM_LEN.

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().

The PinePhone is a smartphone produced by Pine64, with an A64 SoC,
2 or 3 GiB LPDDR3 RAM, 16 or 32 GiB eMMC, 720x1440 MIPI-DSI panel,
and Quectel EG25-G modem.
There are two main board revisions: 1.1 for early adopters, and 1.2
for mass production. Since there is code to detect the board revision
at boot, one config/image can support both boards.
