The HPE SoC is new to linux. A basic device tree layout with minimum
required for linux to boot including a timer and watchdog support has
been created.
The dts file is empty at this point but will be updated in subsequent
updates as board specific features are enabled.

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.

Add support for the HPE GXP SOC timer. The GXP supports several different
kinds of timers but for the purpose of this driver there is only support
for the General Timer. The timer has a 1us resolution and is 56 bits.

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.

The board supports up to 8 GiB memory. The memory is soldered on the
board but the configuration is equivalent to a dual chip select, dual
rank DIMM module.

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.

These frequency calculations depend on the RCW format, which is not
dependent on any particular board. Switch to using ARCH symbols instead
of TARGET.
This whole function could probably use less ifdefs, but for now just do

Signed-off-by: Sean Anderson <sean.anderson@seco.com>
QorIQ platforms now use different clock bindings. Although we don't use
the device tree for clocks on this platform, it is helpful to sync it
because then the bindings will more closely match Linux. Additionally,
it allows for using more clock fractions (such as platform/4).
This corresponds to Linux commit b6f5e7019391 ("ARM: dts: ls1021a:
update the clockgen node").

This adds a driver for the Security Fuse Processor (SFP) present on
LS1012A, LS1021A, LS1043A, and LS1046A processors. It holds the
Super-Root Key (SRK), One-Time-Programmable Master Key (OTPMK), and
other "security" related fuses. Similar devices (sharing the same name)
are present on other processors, but for the moment this just supports
the LS2 variants.
The mirror registers are loaded during power-on reset. All mirror
registers must be programmed or read at once. Because of this, `fuse
prog` will program all fuses, even though only one might be specified.
To prevent accidentally burning through all your fuse programming cycles
with something like `fuse prog 0 0 A B C D`, we limit ourselves to one
programming cycle per reset. Fuses are numbered based on their address.
The fuse at 0x1e80200 is 0, the fuse at 0x1e80204 is 1, etc.
The TA_PROG_SFP supply must be enabled when programming fuses, but must
be disabled when reading them. Typically this supply is enabled by
inserting a jumper or by setting a register in the board's FPGA. I've
also added support for using a regulator. This could be helpful for
automatically issuing the FPGA write, or for toggling a GPIO controlling
the supply.
I suggest using the following procedure for programming:
1. Override the fuses you wish to program
=> fuse override 0 2 A B C D
2. Inspect the values and ensure that they are what you expect
=> fuse sense 0 2 4
3. Enable TA_PROG_SFP
4. Issue a program command using OSPR0 as a dummy. Since it contains the
write-protect bit you will usually want to write it last anyway.
=> fuse prog 0 0 0
5. Disable TA_PROG_SFP
6. Read back the fuses and ensure they are correct
=> fuse read 0 2 4

Especially when using a remote console the response can be so late that
