Changes implementation when using TEE dynamically allocated shared
memory to synchronize with the Linux implementation where the legacy
SMT protocol cannot be used with such memory since it is expected from
device mapped memory whereas OP-TEE shared memory is cached and
hence should not be accessed using memcpy_toio()/memcpy_fromio().
This change implements the MSG shared memory protocol introduced
in Linux [1]. The protocol uses a simplified SMT header of 32bit
named MSG_SMT to carry SCMI protocol information and uses side channel
means to carry exchanged buffer size information, as TEE invocation API
parameters when used in the SCMI OP-TEE transport.

AST2600 supports boot from SPI(mmap), eMMC, and UART.
This patch adds the boot mode detection and return the
corresponding boot device type.

The commit b583348ca8 ("image: fit: Align hash output buffers") places
the hash output buffer at the .bss section. However, AST2600 by default
executes SPL in the NOR flash XIP way. This results in the hash output
cannot be written to the buffer as it is located at the R/X only region.
We need to move the .bss section out of the SPL body to the DRAM space,
where hash output can be written to. This patch includes:
- Define the .bss section base and size
- A new SPL linker script is added with a separate .bss region specified
- Enable CONFIG_SPL_SEPARATE_BSS kconfig option

The HPE SoC is new to linux. A basic device tree layout with minimum

been created.
The dts file is empty at this point but will be updated in subsequent

The GXP supports 3 separate SPI interfaces to accommodate the system
flash, core flash, and other functions. The SPI engine supports variable
clock frequency, selectable 3-byte or 4-byte addressing and a
configurable x1, x2, and x4 command/address/data modes. The memory
buffer for reading and writing ranges between 256 bytes and 8KB. This
driver supports access to the core flash.

The GXP is the HPE BMC SoC that is used in the majority
of current generation HPE servers. Traditionally the asic will
last multiple generations of server before being replaced.
Info about SoC:
HPE GXP is the name of the HPE Soc. This SoC is used to implement many BMC
features at HPE. It supports ARMv7 architecture based on the Cortex A9
core. It is capable of using an AXI bus to whicha memory controller is
attached. It has multiple SPI interfaces to connect boot flash and BIOS
flash. It uses a 10/100/1000 MAC for network connectivity. It has multiple
i2c engines to drive connectivity with a host infrastructure. There
currently are no public specifications but this process is being worked.

Currently, enabling CMD_MISC gives:
cmd/misc.c:67:25: warning: assignment to 'int (*)(struct udevice *, int, void *, int)' from incompatible pointer type 'int (*)(struct udevice *, int, const void *, int)' [-Wincompatible-pointer-types]
Because 'misc_read' takes a void * and 'misc_write' takes a const void
*, both of which make sense for their operation. Given there's one
place we make use of the function pointer, just call read or write
directly for the operation we're called with.

cp.b is used a lot as a way to load binaries to memory and execute
them, however we may need to integrate this with the efi subsystem to
set it up as a bootdev.
So, introduce a loadm command that will be consistent with the other
loadX commands and will call the efi API's.
ex: loadm $kernel_addr $kernel_addr_r $kernel_size
with this a kernel with CONFIG_EFI_STUB enabled will be loaded and
then subsequently booted with bootefi command.

With a 8GiB memory board, it seems that the "very unlikely event" of a
DDR initialization with non-optimal values are not really that unlikely.
It happens in about every other reboot. As described in erratum
A-009942, preset the DEBUG_28 register with an optimal value. The value
iself depends on the memory configuration of the board, but the used
value seems to work well for all variants.

A board might need to get the source of the RCW word, which is also the
boot source in most cases.
These defines are taken from the LS1028A and I expect they are the same
across the SoCs with the same chassis, after all, there was already a
reset source for NOR flash.

Code for changing boot source is platform generic and can be used by any
P1* and P2* compatible RDB board. Not only by boards which use config
header file p1_p2_rdb_pc.h.
So move this code from p1_p2_rdb_pc.h to p1_p2_bootsrc.h and cleanup macros
for generating boot source env variables in CONFIG_EXTRA_ENV_SETTINGS.
This allows to use code for resetting board and rebooting to other boot
source also by other boards in future.

Currently default fallback SDHC mode is 1-bit. Add new config option
CONFIG_SYS_FSL_ESDHC_DEFAULT_BUS_WIDTH to allow specifying default fallback

card during boot process.

8-bit mode is not supported by SD cards and on P2020 are four SDHC pins
shared with SPI (so if P2020 board have also SPI then only 4-bit SDHC mode
is provided). So 8-bit SDHC mode is really bad default.
When max bus width is not provided then set mode to 1-bit. This mode is
supported by all cards, so it is the best option for fallback mode.
Also P2020 bootrom sets mode to 1-bit when booting from SD/MMC card.
